Whether the action potential will be generated or not, if one EPSP depolarizes the initial segment from a resting membrane potential of -70 mV to -65 mV, considering threshold to be -60 mV. Introduction: Postsynaptic potential refers to graded potential that develops in the membrane of a postsynaptic cell. This can be of two types, excitatory postsynaptic potential (EPSP) and inhibitory postsynaptic potential (IPSP).
