Question

Quizplus · Accepted Answer

Gamma-aminobutyric acid (GABA) is a neurotransmitter that usually has an inhibitory effect on the post-synaptic cell. It is the primary inhibitory neurotransmitter in the brain and helps to reduce neuronal excitability. Acetylcholine, glutamate, and dopamine are all excitatory neurotransmitters that usually have a stimulatory effect on the post-synaptic cell.
