Inhibitory postsynaptic potential (IPSP) is the presence of an ionic current flow that hyperpolarizes the postsynaptic neuron. As a result, a greater depolarization than normal is required for excitation and there is only a small probability that there will be an action potential; temporary hyperpolarization of a membrane
