Neurotransmission is kind of signal transmission that involves neurotransmitters that are released by neuron, such as glutamate, aspartate, nitric oxide and dopamine which, further bind to a target receptor present on another neuron. The neuron is involved in the transmission of information. Neurotransmitters can either lead to excitation or inhibition of neurons. Some of the excitatory neurotransmitters are norepinephrine and acetylcholine. Whereas inhibitory neurotransmitters include gamma aminobutyric acid, dopamine and serotonin.
