Which neurotransmitters produce only inhibitory postsynaptic potentials

Question

Quizplus · Accepted Answer

GABA (gamma-aminobutyric acid) is the neurotransmitter that produces only inhibitory postsynaptic potentials. It functions by binding to GABA receptors in the post-synaptic membranes and allows negative chloride ions to flow into the cell, causing it to become hyperpolarized and less likely to generate an action potential. Serotonin, endorphins, and glycine can produce both inhibitory and excitatory postsynaptic potentials depending on the type of receptors that they bind to.
