Neurotransmission is signal transmission which involve neurotransmitters which are released by neuron, such as aspartate, nitric oxide, glutamate, and dopamine which then bind to a target receptor present on another neuron. Neuron helps 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.
