Neurotransmitters are chemicals that transmit signals from the neurons to target cells across a synapse. Packaged into synaptic vesicles that are clustered under the membrane on presynaptic side of the synapse, these are released into synaptic cleft. They bind to receptors located inside the membrane on postsynaptic side of the synapse. There are also some common neurotransmitters that are widely used by medical scientists for regulation of brain and muscles. Examples of Common Neurotrans......
