Question

Quizplus · Accepted Answer

An IPSP (Inhibitory Postsynaptic Potential) occurs when the postsynaptic membrane becomes more negative, moving the membrane potential further from the action potential threshold. This can happen when potassium channels open, allowing potassium to leave the cell, or when chloride channels open, allowing chloride to enter the cell, both of which make the inside of the cell more negative.
