WebbExcitatory PSP-) ou inhibiteur (IPSP -Inhibitory PSP-). Chaque spike pré-synaptique engendre un EPSP; ceux-ci s’ajoutent, quand son potentiel atteint le seuil, le WebbConversely, the binding of a neurotransmitter to an inhibitory receptor site results in an inhibitory PSP, or a negative change in voltage. In this case, it’s less likely that an action potential will be generated in the postsynaptic cell. Unlike an action potential, a PSP doesn’t conform to the all-or-none law.

WebbInhibitory postsynaptic potentials counteract the depolarization of excitatory postsynaptic potentials via membrane hyperpolarization. This mechanism that involves chloride and / or potassium ions will be iscussed in more detail in Tutorial 12. The calcium ion plays other very important roles in neurophysiology.
