Abstract
Purpose: To evaluate the effect of low-intensity photo-stimulation with complex-structured optical signals on visual functions in patients with glaucoma.
Methods: For the stimulation, LED emitters embedded in virtual reality glasses were used, which forms light signals of complex structure with a given fractal dimension. In groups with suspected glaucoma (4 eyes), early primary open-angle glaucoma (POAG Ia, n=5), POAG IIa (n=13), and POAG IIIa (n=17), light stimulation was applied daily: course included 10 séances of 10min. Before and after the course of fractal stimulation, visual fields and colour recognition were examined with standard automatic perimetry (SAP) and the Farnsworth Munsell 100 Hue Colour Vision Test (FM).
Results: In the SAP, mean deviation (MD), which in norm should not exceed −2 dB, before / and after the treatment in averaging for groups of suspected glaucoma, POAG Ia, IIa and IIIa were, respectively, -0.48/-0.43dB, -1.68/-1.38dB, -3.42/-1.75dB, and -14.37/-9.98dB. The pattern standard deviation (PSD) before / and after the treatment for groups with suspected glaucoma, POAG Ia, IIa, and IIIa were, respectively, -1.87/-1,76dB, -1.84/-1.77dB, -1.99/-1.89dB and -6.58/-6.28dB. The FM test was applied to estimate the errors in recognition of green, blue, yellow colours (TES). Before / and after the treatment, the TES data for four mentioned groups consisted, respectively, -12.00/-7,50, -13.60/-11,40, -20.62/-18,62, and -36.53/-32,35.
Conclusion: Low-intensive fractal photo-stimulation significantly improves the SAP indices and colour recognition in eyes with different stages of glaucoma. The pronounced effect of fractal stimulation for the advanced POAG can indicate that at any stage of glaucoma, in the general population of ganglion cells there is a significant percentage of cells that are yet at the plastic phase of reversible functional changes and capable of responding positively to medical or physical neuroprotective therapy. Further confirmation of the stability of effects is required in studies on a more massive cohort.

Title: Neurorehabilitation Algorithms In Patients With Post-Stroke Hemiparesis And Hemiparetic Shoulder (a comparative study of eight neurorehabilitation complexes)
11:50-12:10
Biography
Abstract
Aim: Our goal was to evaluate the efficacy of application of different physical modalities and neurorehabilitation methods on independence in activities of daily living (ADL) in patients with post-stroke hemiparesis and hemiparetic shoulder.
Material & Methods: We observed a total of 216 post-stroke patients with hemiparetic shoulder. We effectuate clinical approbation of different neurorehabilitation (NR) algorithms. Patients were randomized into eight therapeutic groups (27 per group). In all patients, the NR course (20 days) includes a basic physiotherapy complex. In group (gr 1) we applied only cryokinesitherapy; in gr 2 - physiotherapy and ergotherapy (occupational therapy). In the next groups we added some pre-formed modality: low frequency low intensity Magnetic Field (gr 3), Interferential Currents (gr 4), Ultrasound (gr 5), Deep Oscillation (gr 6), low-intensity Lasertherapy (gr 7), Functional electrostimulations of the deltoid muscle (gr 8). Patients were controlled before, during and at the end of the NR course (of 20 treatment days) and one month after its end using a battery of clinical methods and functional scales.
Results & Discussion: The comparative analysis of results shows a significant reduction of pain, improvement of functional capacity and autonomy (Brunnstrom, Barthel); increase of the range of motion of the humero-scapular joint (goniometry). Cryokinesitherapy is effective on the orthopedic dysfunction of the humeral joint, ergotherapy is on the range of motion and the functional recovery of the upper extremity. In cases with intensive pain, the magnetic field and deep oscillation are most efficient; in humero-scapular periarthritis, ultrasound and laser therapy are used; in throphic alterations (osteoporosis of the humeral head) – interferential currents and laser therapy are efficient. Goniometrical indices (range of motion of the joint) are significantly increased by electrostimulations and ergotherapy.
Conclusion: We must underline that the structured neurorehabilitation algorithms must be individualized in every case.

Title: Understanding brain dysfunctioning in Trisomy 21 through alterations of monamine pathways in transgenic mice for chromosome 21 genes
12:10-12:30
Biography
J London (Emeritus Professor at University Paris-Diderot) has completed her PhD in the Pasteur Institute under the direction of Professor Jacques Monod (Nobel Prize winner) and Professor Michel Goldberg in the field of Protein Folding and Bacteriology (3 papers). She moved to immunology in Necker’s hospital under the direction of Professor Jean François Bach and then was a visiting scientist at NIH (9 papers). After coming back to Paris she settled a laboratory in Molecular Biology at the Blood Centre and cloned glycophorins A and B (13 papers). She then moved again to Necker’s Hospital where she joined the group working on Trisomy 21 and settled a laboratory to obtain transgenic mice for the SOD1 gene and cloned the murine CBS. She published some 35 papers on different aspects of Trisomy 21 using transgenic mice for some chromosome 21 genes: APP CBS, DYRK1A and SOD1.
Abstract
Trisomy 21 (T21/ Down syndrome: DS) is characterized by reduced cognitive capacities, behavioural alterations and early ageing with a high risk to develop dementia earlier than in the general population. In order to understand neurobiological mechanisms which contribute to this large pathophysiology, murine models have been raised overexpressing one, two or several chromosome 21 genes. Some of these models have already provided a lot of information leading even to some therapeutic approaches. Although alterations in some monoamines neurotransmitters have been shown in various brain areas or in serum/plasma from individuals with trisomy 21, very few information have been obtained in the animal models. We will present recent data obtained by HPLC-EC, showing how overexpression of APP, CBS, Dyrk1A genes induce different modifications in the serotoninergic, dopaminergic and adrenergic pathways in the four brain areas studied (hypothalamus, thalamus, hippocampus and striatum). Indeed DYRK1A or/and APP overexpression induce mainly alterations in the serotoninergic and the noradrenergic pathways while CBS overexpression induces mainly modifications in the dopaminergic pathway. Moreover we will show that there is not only a genotype effect depending on the brain areas studied but also a dramatic gender effect. As these genes are involved in neurogenesis, early neurodegeneration and some physiological aspects present in persons with T21, the clear evidence of alterations in monoamines neurotransmitters related to overexpression of one of these genes might facilitate the development of novel disease-modifying strategies.

Abstract
The role of movement in the development of cognitive, emotional and social development was relatively neglected until recently. Only recently have psychologists come to appreciate that acting and knowing are inseparable. The young child’s motivation to reach is at the foundation of a perception action cycle, which creates new skills and hence new opportunities for cognitive development. Failure to move in a typical manner in early childhood is a predictor of difficulties later in life. Infants who were more motorically mature and who explored more actively at 5 months of age achieved higher academic levels as 14-year-olds. The developmental cascade arising from the child’s movements, leads to perceptual, cognitive and social development. A research topic Autism: The Movement Perspective opened up in Frontiers in Integrative Science (2013) and was followed by over 30 scientific research articles on the topic from research institutions around the world. An editorial for the research topic: ‘Autism: The Movement Perspective’ wrote that movement could be our best ally in autism, at all fronts. Studies of human movement demonstrate the intentionality of movement even as early as the second trimester in utero. Autism spectrum disorders (ASD) has its origin in early prenatal failure of movement, timing and coordination. Foetuses that move in an atypical manner may, post-partum, display a problem in qualitative and temporal-dynamic control, i.e. flexibility in affective response and precision in motor timing. This is associated with delay in cognitive development and language, which in turn is associated with a diagnosis of ASD.

Abstract
Objectives: Since the central-nervous-system (CNS) is the second most frequently affected organ in mitochondrial disorders (MIDs) and since pediatric MIDs are increasingly recognized, it is important to know about the morphological CNS abnormalities on imaging in these patients. The review aims at summarizing and discussing current knowledge and recent advances concerning CNS imaging abnormalities in pediatric MIDs.
Methods: Systematic literature review.
Results: The most relevant CNS abnormalities in pediatric MIDs on imaging include white and grey matter lesions, stroke-like lesions as the morphological equivalent of stroke-like episodes, cerebral atrophy, calcifications, optic atrophy and lactacidosis. Since these CNS lesions may go along with or without clinical manifestations, it is important to screen all MID patients for cerebral involvement. Some of these lesions may remain unchanged for years whereas others may be dynamic, either in the sense of progression or regress. Typical dynamic lesions are stroke-like lesions and grey matter lesions. Clinically relevant imaging techniques for visualization of CNS abnormalities in pediatric MIDs are the computed tomography, magnetic-resonance-imaging, MR-spectroscopy, SPECT, PET, and angiography.
Conclusions: CNS imaging in pediatric MIDs is important for diagnosing and monitoring CNS involvement. It also contributes to the understanding of the underlying pathomechanisms that lead to CNS involvement in MIDs.

Title: Neurophysiological correlates of hypnosis and its clinical application in the management of chronic pain
14:20-14:40
Biography
Abstract
Since 1992, hypnosis has become routine practice in our surgery services. Revivication of pleasant life experiences has served as the hypnotic substratum in a series of over 9,000 patients. In retrospective studies followed by randomised prospective studies, we have confirmed the usefulness of hypnosedation (hypnosis in combination with conscious IV sedation) and local anaesthesia as a valuable alternative to traditional anaesthetic techniques. Medical hypnosis is also a safe and effective complementary technique in the treatment of chronic pain syndromes. Learning selfhypnosis/selfcare improves not only pain but also psychological factors such as depression, anxiety, pain disability and improves patient’s global impression of treatment effectiveness. The relevance of mind-body interventions to reduce emotional distress in breast cancer patients was also studied. Selfhypnosis/selfcare learning decreases distress and fatigue, insomnia and increases quality of life, as well as emotional functioning in these cancer patients. In a context of a socio-economic crisis, it is essential to develop health intervention treatments with a significant effectiveness combined with a low cost for the patient. Futures studies should consider comparing selfcare learning and selfhypnosis interventions separately to disentangle the effect of hypnosis from the effect of selfcare learning in the management of chronic pain.

Title: Tinnitus, a Neurological Disorder Underlined by an Alteration of Synaptic Plasticity in the Auditory Brainstem
14:40-15:00
Biography
Abstract
Tinnitus, the phantom perception of sound, affects 10 to 15% of the adult population worldwide. Despite its prevalence, there are still no U S Food and Drug Administration (FDA)- or European Medicines Agency (EMA)-approved drugs on the market that target tinnitus. Over the past decade, numerous studies suggest that tinnitus results from an increased central gain in response to cochlear damage and hearing loss. Our previous studies shed light on dysfunctional excitability in the central auditory system during hearing loss. Here, we show that exposure to loud sound leading to hearing loss and tinnitus triggering a deficit in synaptic plasticity due to an increased release probability of glutamate in the central auditory brainstem. More importantly, we show that in vivo administration of magnesium threonate promotes recovery from these deficits, and allows recovery using an experimental model of tinnitus. The significance and novelty or our study is linked to the physiological relevance behind the modulation of long-term potentiation (LTP), the neural basis for learning and memory. We showed that LTP alterations form a memory trace in the dorsal cochlear nucleus that is related to the phantom perception of auditory objects. Decreasing release probability could potentially lead to the development of novel treatments for tinnitus and open new avenues for understanding cellular and network mechanisms linked to aberrant auditory perceptions. Although tinnitus is caused by cochlear dysfunction, it is actually a neurological disorder for which underlying cellular mechanisms remain poorly understood. Our study highlights a novel role for synaptic plasticity in an auditory brainstem nucleus and describes cellular mechanisms behind a therapeutic intervention against tinnitus.

Title: Application of Artificial Intelligence Machine Learning to Diagnose and treat Neurobehavioral Disorders, specifically Autism
15:20-15:40
Biography
Abstract
Current tools utilized to diagnose neurobehavioral disorders such as autism are time consuming and require specialized training. The length of the current standard exam as well as the need for administration in a clinical facility contributes to delay in diagnosis and an imbalance in coverage of the population needing attention. Families typically wait months between initial screening and diagnosis and even longer if part of a minority population or lower socioeconomic group. These delays directly translate into postponements to the delivery of early intervention services, which if started before 36 months have the potential for significant and positive impacts on a child’s development. Based on the initial work of Dennis Wall, PhD at Harvard and Stanford Universities, Cognoa, Inc has developed a proprietary machine learning algorithm to detect autism spectrum disorder with high accuracy in children ages 18-72 months utilizing a questionnaire and analysis of short videos of the children provided by the parent. Clinical validation of the algorithm was done in a multi-center clinical trial at three tertiary care centers specializing in autism diagnosis (The Thompson Center at the University of Missouri, Vanderbilt University, and the University of South Carolina). Receiver operating characteristic (ROC) curves for current screening tools versus Cognoa’s algorithm demonstrate superiority. Furthermore, the average age of children identified by Cognoa as high-risk for autism was 3.08 years old, which is 13 months sooner than the US national average for autism diagnosis of 4.17 years. This earlier identification affords parents the ability to seek help for their children during the critical treatment window for which the software provides home based developmental activities based on the features identified during the assessment.

Abstract
Introduction: Awake craniotomy with intraoperative brain mapping allows for maximum tumor resection while monitoring neurological function and is used for lesions involving the eloquent areas of the brain, such as Broca's, Wernicke’s, or the primary motor area. Commonly used techniques are monitored anesthesia care (MAC) with an unprotected airway, or the AAA technique, with a partially or totally protected airway.
Method: A prospective data collection and retrospective data analysis was conducted on 81 patients who underwent an awake craniotomy for an eloquent brain lesion over a 9 year period. 50 patients underwent anesthesia with the MAC technique and 31 patients underwent the AAA technique by a single surgeon and a team of anesthesiologist. MAC technique: no set protocol for sedation. Different medications for MAC based on the comfort level of anesthesiologist, requirements of the patient and whether the scalp block is working well. AAA technique: Propofol was used for induction followed by laryngeal mask airway placement. Anesthesia was maintained with sevoflurane until the patient was spontaneously ventilating and asleep. Scalp Block: a complete scalp block was performed in all patients. Infiltrative block is performed at the pinning site, incision site and after craniotomy around the nerves supplying the duramater. Bupivacaine or Ropivacaine of 0.5% with 1:200,000 epinephrines is usually used.
Results & Conclusion: Operative time is shorter in the MAC group versus the AAA by about 30 minutes. Hypertension is the most common intraoperative complication. Intraoperative seizures incidence is 4% in the MAC group and 3.2% in the AAA group.

Title: Study of the Vascular and Neuronal network in the spinal cord for preclinical application
16:20-16:40
Biography
Abstract
Anomalous developments or damages to the vascular network (VN) of the CNS, as well as an impaired partnership with neurons and glia are related to pathology. Several studies have found that the early detection of vascular diseases in the brain may lead to an increased ability to perform premorbid diagnosis of the Alzheimer Disease. On the other hand, traumatic spinal cord injuries induce microvascular changes that may contribute to secondary injuries and deficits observed in patients. In particular, the ischemia and the extravasation of the blood components resulting from such injuries contribute to a series of effects such as edema formation, neuronal cell death, and damage to white matter tracts. Studying the complexity of the VN and neuronal network in a large volume of tissue, with a resolution sufficient to access the smallest capillaries and the neuronal ultra-structure, appears then as a key point for a better understanding of the neuro-vascular coupling. Nevertheless, conventional 2D imaging yields incomplete spatial coverage, whereas conventional 3D imaging does not achieve sufficient resolution and contrast. X-ray phase-contrast μTomography (XrPCμT) has great potential for the investigation of the structures that generate poor contrast by absorption, since the XrPCμT sensitivity to light elements is about 1000 times higher than by X-ray absorption contrast methods. By X-ray high-resolution phase-contrast tomography, we performed a simultaneous 3D imaging of the VN and of the neurons of the mouse spinal cord. The cellular images show the 3D distribution of axons bundles, the neuronal soma and the synaptic junction. The study of CNS diseases and of traumatic spinal cord injuries are two of the most significant examples of applications that could take advantage of our approach, which is a crucial complementary tool for pre-clinical investigation and would allow for solving the entangled relationship between the VN and for the neuronal system.

Title: ErbB2 regulates autophagic flux to modulate the proteostasis of APP-CTFs in Alzheimer's disease
17:00-17:20
Biography
Abstract
Proteolytic processing of amyloid precursor protein (APP) C-terminal fragments (CTFs) by γ-secretase underlies the pathogenesis of Alzheimer’s disease (AD). An RNA interference screen using APP-CTF [99-residue CTF (C99)] and Notch-specific γ-secretase interaction assays identified a unique ErbB2-centered signaling network that was predicted to preferentially govern the proteostasis of APP-C99. We then found that ErbB2 effectively suppressed autophagic flux by physically dissociating Beclin-1 from the Vps34–Vps15 complex independent of its kinase activity. Down-regulation of ErbB2 by CL-387,785 decreased the levels of C99 and secreted amyloid-β in cellular, zebra fish and mouse models of AD, through the activation of autophagy. Oral administration of an ErbB2-targeted CL-387,785 for 3 weeks significantly improves the cognitive functions of APP/PS1 transgenic mice. This work unveils a non-canonical function of ErbB2 in modulating autophagy and establishes ErbB2 as a novel therapeutic target for AD.

Abstract
Background: Multiple sclerosis (MS) is an inflammatory demyelinating disease affecting more than 2 million people worldwide and considered a leading cause of non-traumatic disability in young adults in many countries.
Objective: To evaluate the mitochondrial dysfunction in patients with multiple sclerosis (MS) by investigating serum levels of lactate and uric acid (UA) in MS patients and to explore their potential role in pathogenesis of MS as biological markers for monitoring disease activity and progression.
Methods: This case-control study was conducted on 52 Egyptian subjects (32 multiple sclerosis patients and 20 normal healthy individuals as control. Patients were subjected to thorough history taking, detailed neurological examination and clinical assessment of the severity of the disease using Expanded Disability Status Scale (EDSS) and fatigue using Fatigue severity scale (FSS). Serum level of lactate and uric acid were measured in both groups.
Results: In comparison to the control group, subjects with multiple sclerosis had statistically significant higher serum level of lactate (p= 0.001), with no statistically significant difference in serum levels of UA (p= 0.337). There was statically significant negative correlation between serum lactate levels and EDSS-FSS, but no statistically significant correlation between serum UA levels and EDSS or FSS.
Conclusion: MS patients have significantly higher serum lactate level. This can support the hypothesis that mitochondrial dysfunction has an important role in the underlying pathogenic mechanism of the disease. However, the potential value of serum lactate as a marker for monitoring disease activity and progression is questionable.

Abstract
Introduction: Over a 14 days course we studied the effects of high frequency repetitive Transcranial Magnetic Stimulation that was applied over the primary motor cortex (M1) bilaterally to patients with Multiple Sclerosis (MS) with EDSS ranging from 2,5-6,5. All procedures were done in a clinical setting. In addition to that, we have applied Cu So4 electrophoresis over the Spinal cord region. We studied a heterogeneous group of 65 patients with MS - 51 of them with muscle spasticity; 30 with decreased muscle strength; 25 with bladder control impairment and 50 with mood changes and fatigue.
Methods: We used Timed 25 foot walk test; Modified Ashworth Spasticity scale; The five point scale for muscle strength; Bowel and Bladder control scales from the Multiple Sclerosis Quality of life inventory and Fatigue Severity scale; and Depression inventoty scale. The patients were tested on the first and 14th day of the treatment.
Results: Most of the symptoms (excluding fatigue) were significantly improved. 67% of the patients showed decreased muscle spasticity and thus, less weakness and improved gait. 68% showed improved mood.
18% reported positive outcome in Bladder control impairment. Faster ( in 5-7 procedures ) improvement was recorded in patients with EDSS from 2,5 to 4. None of the patients had any serious adverse side effects.
Conclusion: High frequency repetitive Transcranial Magnetic Stimulation is beneficial in the management of motor and affective symptoms in patients with Multiple Sclerosis . The procedure is well tolerated and has an excellent safety profile.

Abstract
Parkinson’s Disease (PD) is the second most common neurodegenerative disorder worldwide effecting 1% of the population over 60 years of age. In addition to its restrictive effects in motor function, autonomus nervous system and cognitive functions are also effected. When levodopa is combined with peripheral decarboxylase inhibitors, symptom relief has been observed for a couple of years, however, many adverse effects including dyskinesias occur. Amantadine, anticholinergics, entecapone/talcapone, selegiline, dopaminergic receptor agonists all work for a limited period of time. Gene therapy, fetal substantia nigra tissue implantation have all been tried, however, the results have been inconclusive. Antiapoptotic drugs, glutamate antagonists and antiinflammatory drugs were used for their antioxidant effects and deep brain stimulation has also been applied as functional neurosurgery. Some vaccines have also been tried after the significant role of neuroinflammation has become evident. In the studies conducted in our laboratory, the anticonvulsant drug valproic acid has been found to be effective by producing antioxidant and antiapoptotic effects. Epigenetic modulation was also effective. In an animal model of Parkinson’s disease developed in rats stereotaxic injection of 6-OHDA (8μg/2μL) or saline (2μL) to the right substantia nigra pars compacta was done. The following coordinates of substantia nigra pars compacta was used: (AP) = –4.8 mm, (ML) = –1.8 mm and (DV) = –8.2 mm. Only the rats showing pronounced rotational behaviour (more than 5 contralateral turns) were included in the study after apomorphine (0.5 mg/kg sc) test. The effects of valproic acid were compared with levodopa. The studies are underway to study the molecular mechanisms behind Parkinson’s disease.

Abstract
The objective of current work is to emphasize on the impact of neurorehabilitation as a contemporaneous approach to Brain Activation. The goal was to prove and evaluate the efficacy of application of different modalities and methods of the physical and rehabilitation medicine (PRM) on independence and quality of life of neurological and neurosurgical patients. We effectuated a composition, clinical application and approbation of complex neurorehabilitation algorithms in patients with neurological and with neurosurgical conditions. Patients were divided into a lot of groups and subgroups, in each one we applied a different neurorehabilitation complex, composed by a synergic combination of natural and pre-formed physical modalities (electrical currents, laser, cryo/thermo-agents, hydro-/balneo-/ peloido-therapy; physiotherapy and occupational therapy). Patients were controlled before, during and at the end of the neurorehabilitation course and one month after its end - using a battery of traditional and contemporaneous objective methods: tests and scales for motor deficiency, balance and coordination; functional grip of the upper limb; gait and independent motion; independence in activities in daily living (ADL: self-service, family, professional and social life); depression and anxiety; visual analogue scale of pain; vibroesthesiometry; thermosensibility; laser Doppler flowmetry; ICF assessment. Based on detailed qualitative and quantitative evaluation, we proved the efficacy of application of different neurorehabilitation programmes – on different types and levels of sensory, motor and functional deficiency. In conclusion, we emphasize on the capacity of physical modalities for functional recovery and amelioration of independence in everyday life of patients with diseases and conditions of the nervous systems. Our opinion (based on 30 years clinical practice) is that neurorehabilitation must be considered as an important approach to brain activation and must be involved in the everyday clinical practice of neurological and neurosurgical wards.

Abstract
After focal ischemic injury of brain such as stroke, activity of remaining neural network is changed to optimize neural resources for recovery of function. Neuroplasticity plays an important role in coordinating neural interactions on different levels from cellular changes to wide-range cortical remapping for recovery from ischemic brain injury such as stroke. An experience-dependent synaptic and circuit plasticity remodels synaptic buttons and connections by repeated sensory experience. Modulation of neuroplasticity may enhance the rehabilitative outcome and functional restoration after stroke; therefore, it is a crucial topic of neurorehabilitation. Noninvasive brain stimulation (NBS) has recently been adopted for modulating neural excitability in a noninvasive manner and consequently enhancing neural recovery after stroke. The most popular noninvasive methods of neuromodulation include transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), and transcranial alternating current stimulation (tACS). After a stroke, interhemispheric imbalance of cerebral cortical excitability occurs and cortical activity in the contralesional hemisphere is abnormally increased. On the other hand, brain activity in the ipsilesional hemisphere is decreased by interhemispheric inhibition of the contralesional hemisphere. NBS has been used to recover disrupted interhemispheric balance caused by stroke onset by modulating cortical excitability over specific brain regions. Cortical excitability can be modulated depending on the frequency of rTMS and the tDCS direction of current. This intervention can lead to the improvement of residual motor function by inducing neural plasticity. NBS has been mainly performed to restore abnormal interhemispheric balance by facilitating ipsilesional primary motor cortex (M1) excitability or by inhibiting contralesional M1 excitability. Recently, more challenging approaches, such as stimulation of two or more sites or use of dual modalities have been studied in stroke patients. One of the considerations on the effect of NBS is individual variation of its responsiveness. Diverse factors such as individual skull and cortical morphology, lesion location and severity, genetic polymorphism, etc. are considered as the intrinsic factors affecting individual response variability. The individually-tailored neural network modulation by customized NBS technique considering multiple influencing factors may enhance functional recovery and provide successful neurorehabilitation outcome after stroke. The modulating effect of NBS can expand to the interconnected subcortical network areas beyond the site of cortical stimulation. Use of multimodal functional neuroimaging methods such as functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI), electroencephalography (EEG), functional near infrared spectroscopy (fNIRS) can demonstrate the network effect of NBS. Neural plasticity after stroke can be seen from microscopic to macroscopic levels. This process may be spontaneous or induced by training, although the former occurs only within a critical period after injury. A novel neurorehabilitation strategy of using personalized NBS methods in combination with various rehabilitation techniques can further maximize functional recovery after stroke.

Abstract
Techniques previously used to investigate damage to vascular and neuronal networks in neurological disorders suffer from several limitations. In particular, 2D imaging restricts spatial coverage, entails destructive sample preparation, and may lead to data misinterpretation due to lack of information on the third dimension. In contrast, recent ex-vivo study in mice demonstrated that imaging by X-ray phase-contrast tomography (XPCT) enables the study of the 3D distribution of both vasculature and neuronal networks, without sample sectioning or specific preparation. We have generated and quantified multiscale XPCT to evaluate alterations in vascular and neuronal networks at relevant disease phases of the animal model for multiple sclerosis, experimental autoimmune encephalomyelitis (EAE), in affected mice and to understand how treatment with mesenchymal stem cells (MSC) modifies them. A direct 3D morphological description of EAE lesions is provided at both vascular and neuronal levels at two different length scales, from the whole spinal cord up to capillaries and single cell. Such a multi-scale direct analysis has never been performed to understand EAE pathology and address the effect of an innovative therapeutic strategy. The results strongly indicate i) a trend in alteration of the micron vessels and occlusions in the capillaries, an observation never obtained in tissue without the use of a contrast agent; ii) neuronal alterations with massive loss of lower motor neurons. Such vascular and neuronal alterations were considerably reduced in MSC-treated mice. We have also applied XPCT to the investigation of other neurodegenerative disorders, i.e. Alzheimer and amyotrophic lateral sclerosis (ALS) and the results will be presented.

Abstract
The use of behavioural tests has been extensively used to evaluate animal recovery during potential treatment evaluation in neurological diseases, as well as the progression of certain degenerative conditions (e.i stroke multiple sclerosis, degenerative cervical myelopathy). Nevertheless, despite the remarkable number of researchers and the large number of papers published every year, we are failing in translate these results from animal models into humans. Regardless of the differences between humans and rodents and the complexity working in neurological diseases, one more level can be reached to overcoming this obstruction by promoting the standardization of behavioural test among different laboratories. This strategy will allow a direct comparison between the results generated by different laboratories working on the same animal model. One of the more challenging tasks in experimental stroke research is measuring long-term functional outcome in mice. It is, however, becoming more important, since transgenic mice are increasingly used for modelling human neurological disorders. Using Cat Walk, we characterized long-lasting gait/locomotion deficits following mouse distal middle cerebral artery occlusion (dMCAO). The post-dMCAO assessment was performed at 7, 14, 21, and 28 days after experimental ischemia. All parameters measured in dMCAO and Sham-operated groups reached similar levels at four weeks after the experimental insult, which reflects a spontaneous post-ischemic recovery. Based on our investigation, we conclude that CatWalk represents a relevant and sensitive analysis, which allows long-term characterization of animal functional recovery in the dMCAO model of experimental ischemia.

Abstract
With the increasing attention given to concussions in the media, referrals for management and treatment of concussions have increased. Understanding how to actively manage concussions and post-concussive syndrome including return to cognitive activity, rehabilitation and return to physical activity, addressing the mental health aspects of concussion, and how to answer difficult questions such as what is my risk for chronic traumatic encephalopathy? are essential for proper management of concussion. Clinicians should be familiar with the pathophysiology of concussions and the key elements of an initial concussion evaluation. The role of computerized neuropsychological testing along with its utility and limitations are reviewed. A review of the current literature as well as research in the field of concussion is presented.

Title: Ketamine: new perspective to an old drug
12:00-12:20
Biography
Abstract
Ketamine is a versatile drug used mainly as analgesic and general anaesthetic, but lately has enjoyed a recent renaissance as a potential treatment for a range of neurological and psychiatric disorders. Ketamine has shown promise as an antidepressant that acts within minutes to hours, rather than weeks or months. Other studies have shown that ketamine might help in other psychiatric diseases, such as bipolar disorder, obsessive-compulsive disorder, and post-traumatic stress disorders. On the other side, the potential for misuse, including addiction, make ketamine a very controversial drug. Through this session we will look at the evidence of ketamine in the treatment of depression disorders and the potential role as a modulator in impulsive disorders.

Abstract
Although circular RNAs (circRNAs) are a subtype of non-coding RNAs enriched in the mammalian brain, nothing is known about their potential involvement in psychiatric and neurodevelopmental disorders. Here, we first show that circHomer1, a circRNA derived from Homer protein homolog 1 (HOMER1), is reduced in the orbitofrontal cortex (OFC) and in stem cell-derived neuronal cultures from patients with schizophrenia (SCZ) and bipolar disorder and is inversely correlated to the relative abundance of HOMER1B mRNA isoform. Using in vivo knockdown of circHomer1 in mouse OFC, we show that it modulates the synaptic localization of Homer1b and is necessary for OFC-mediated reversal learning. Moreover, we demonstrate that circHomer1 inhibits synaptic transmission and binds to an RNA-binding protein that can increase its synaptic localization. Lastly, a SCZ-linked single nucleotide polymorphism is associated with reduced OFC circHomer1 expression and altered local functional connectivity. Collectively, these data introduce a novel psychiatric disease-associated circRNA that regulates synaptic gene expression, neuronal function, and cognitive flexibility. In parallel, we show data of altered circRNA expression in fetal brains of an animal model of Fetal Alcohol Syndrome Spectrum Disorders. Ongoing experiments are aiming at examining the effects of ethanol-induced circRNAs on neuronal development and synaptic plasticity in mouse brain and human pluripotent stem cell-derived neuronal cultures.

Abstract
Diabetes and other vascular injuries are known to cause the neurodegeneration in peripheral as well as central nervous system. The phenomenon of neurodegeneration is also known to cause the neuropathic pain and cognitive dysfunction. Sciatic nerve injury (SNI) has documented to produce the neuropathic pain and cognitive dysfunction. Folic acid is one of the micronutrients for the development and protection of neurodegenerative disorders. The objective of the present study is to investigate the role of folic acid in SNI induced cognitive dysfunction in rat model. SNI clinically mimics the diabetic neuropathy and neurotrauma associated cognitive dysfunction. The cognitive function was assessed by using Morris water maze (MWM) test in terms of escape latency time (ELT) which helped in accessing acquisition (learning) trail and time spent target quadrant (TSTQ) and retrieval (memory) trail. In addition, the biochemical tests such as thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH), acetyl cholinesterase (AChE) activity and total protein were also estimated in brain tissue sample. The administration of folic acid (10 and 20 mg/kg, p.o.) for 10 consecutive days significantly (P < 0.05) attenuated SNI induced by increase ELT and decrease TSTQ levels. Further, it also produces the ameliorative effect on SNI induced raise in TBARS, AChE activity and decrease in GSH levels when compared to sham control group. The study was compared with the treatment of donepezil (standard drug, 1 mg/Kg, p. o.) for 10 consecutive days which has also shown similar effects. Hence, it may be concluded that, folic acid may be a newer candidate for the management of cognitive dysfunction with peripheral nerve injury condition.

Title: Investigating visual strategies during the recognition of static and dynamic facial affect in TBI and control cohorts
14:50-15:10
Biography
Leanne has completed a BSc in Psychology and an MSc in Applied Cognitive Neuroscience. She is near the completion of her PhD, supported by Sheffield Hallam University, which has investigated social cognition and saccadic eye scan patterns in TBI and control groups. She currently works as an Assistant Psychologist for Rotherham Doncaster and South Humber NHS Trust in the Neuro Rehabilitation Outreach and Stroke team. Socioemotional problems post-TBI are often not assessed or rehabilitated (Kelly, McDonald & Frith, 2016) and Leanne is passionate about raising awareness of social cognition after TBI and in the future developing contemporary and ecologically valid clinical assessments and rehabilitation programmes.
Abstract
Objectives: Traumatic brain injury (TBI) often precipitates socio-emotional problems which impinge on social relationships. Although socio-emotional impairments are debilitating the mechanisms underpinning these are poorly understood. Social interactions are dynamic yet research frequently employs static assessments. We investigated eye scan patterns of TBI and controls viewing static/dynamic facial expressions.
Design: Factorial analysis investigated correct response, reaction time, fixation duration/count to areas of interest (eyes, nose and mouth) across six emotions (anger, disgust, fear, happy, sadness and surprise).
Methods: 17 TBI participants were recruited from the NHS and age/gender matched controls were recruited using stratified opportunity sampling. Images from the Amsterdam Dynamic Facial Expression Set (ADFES) were presented on a Tobii T120 Eye Tracker screen. Multivariate and correlational methods were used to analyse data.
Static Results: Controls displayed greater fixation durations; counts to eyes were more accurate and quicker identifying emotions than TBI participants. The TBI group focused more on the nose compared to controls. Higher scores on the ADFES correlated with quicker responses across all emotions for all participants and positive relationships between empathy, emotion recognition and fixation patterns were revealed. Gaze-patterns for the six emotions differed slightly between the groups although fearful faces induced more/longer fixations and happy faces the least/shortest fixations.
Dynamic Results: Controls were more accurate at identifying emotions than the TBI group but no group differences were found for gaze-patterns. Happy faces induced more/longer fixations and sad faces the least/shortest fixations. A positive correlation between correct scores on the ADFES and empathy scores across all emotions for all participants was established.
Conclusions: Irregular gaze-patterns could underpin some socio-emotional problems after TBI, highlighting the potential for innovative rehabilitation approaches. Visual strategies underlying the recognition of static/dynamic emotions may differ. The key limitation was the small sample size which will hopefully be rectified in future work.

Biography
Hamada I Zehry is a consultant neurologist and have special interest in child neurology and abnormal movement. He had accepted poster presentation in child neurology section in last world congress of neurology Kyoto. Japan. He is PhD degree candidate since 2012 (in last part of PhD). He is working on the thesis entitled as, Basal Ganglionic Lesions In Egyptian Children: Radiological Findings In Correlation With Etiology And Clinical Manifestations.
Abstract
Background: In childhood, the metabolic activity of the basal ganglia is greater and they are particularly prone to injury. Damage to the basal ganglia cells may cause problems controlling speech, movement, consciousness, muscle tone, posture and cognition.
Aim of the study: To determine the etiology of basal ganglionic disorders in a sample of Egyptian children.
Methods: A cross sectional observational study was utilized on 34 patients attended at the Pediatric Neuro Outpatient Unit of Neurology department at Al-Azhar University Hospitals during a period of one year from the beginning of November 2014 to the end of November 2015. A specialized pediatric neurological sheet, cognitive assessment in children using Stanford-Binet Intelligence Scale and Laboratory investigations were performed. The included patients were classified according to MRI into two groups; ganglionic group that included patients with isolated basal ganglionic lesions (n=23) and para-ganglionic group that included patients with combined ganglionic as well as para-ganglionic lesions (n=11).
Results: The frequency of male patients was slightly higher than the female patients in both groups without significant difference (13(56.5%) versus 6(43.5%) and 10(54.5%) versus 5 (45.5%), in ganglionic and para-ganglionic groups, respectively). Acute ischemic stroke was the most frequent cause, which was found in 12(35.3%) cases, followed by 10(29.4%) had metabolic and infectious causes, and lastly 2(5.9%) had toxic causes. The incidence of toxic causes (CO poisoning) was significantly higher among ganglionic group compared to para-ganglionic group (2(8.7%) versus 0(0.0%), respectively). According to brain MRI imaging, bilateral basal ganglion affection was the most frequent lesions among ganglionic group 16 (69.7%) while temporal affection (temporal were 2(18.2%), tempro-parietal were 2(18.2%) and tempro-occipital was 1(9.1%) ) was the most frequent lesions among para-ganglionic group5(45.5%).
Conclusion: Acute ischemic stroke was the most frequent cause of basal ganglionic lesion in a sample of Egyptian children.
