Medical Term:

inhibitory postsynaptic potential

 

Definition: 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.
