Summary Introduction

To explain:

The difference between inhibitory postsynaptic potentials and excitatory postsynaptic potentials.

Introduction:

Post synaptic potentials are the changes in “membrane potential” of the postsynaptic terminal of the chemical synapses. It provides temporary change in the electric polarization of the membrane of nerve cell. Postsynaptic potentials are graded potential and should not be compared with action potential. Two types of postsynaptic potentials are present: inhibitory postsynaptic potentials and excitatory postsynaptic potentials.
