During an inhibitory postsynaptic potential
WebAn inhibitory postsynaptic potentials (IPSP) is a temporary hyperpolarization of postsynaptic membrane caused by the flow of negatively charged ions into the postsynaptic cell. An IPSP is received when an inhibitory presynaptic cell, connected to the dendrite, fires an action potential. WebFeb 14, 2024 · Exciting the postsynaptic neuron leads to a firing of action potential (electrical impulses), whereas inhibiting the postsynaptic neuron prevents the …
