There are more than 50 chemical substances have been proved or postulated to function as synaptic transmitters. Many of them are listed in below, which give two groups of synaptic transmitters. One group comprises small-molecule, rapidly acting transmitters. The other is made up of a large number of neuropeptides of ... Read More

Synaptic transmission is a key process whereby presynaptic neurotransmitter release drives electrical and biochemical signals via opening of postsynaptic channels. 7 Steps of Synaptic Transmission Step 1: An action potential arrives at the axon terminal Step 2: Membrane depolarization from action potential causes influx of calcium ions Step 3: Docking ...
