inhibitory postsynaptic potential

in·hib·i·tor·y post·syn·ap·tic po·ten·tial (IPSP),

the change in potential produced in the membrane of the next neuron when an impulse that has an inhibitory influence arrives at the synapse; it is a local change in the direction of hyperpolarization; the frequency of discharge of a given neuron is determined by the extent to which impulses that lead to excitatory postsynaptic potentials predominate over those that cause inhibitory postsynaptic potentials.
