An inhibitory postsynaptic potential (IPSP) is associated with_________ .
A) opening of voltage-regulated channels
B) lowering the threshold for an action potential to occur
C) hyperpolarization
D) a change in sodium ion permeability

Question

Quizplus · Accepted Answer

An IPSP is associated with hyperpolarization, which means the membrane potential becomes more negative, making it harder for an action potential to occur. This is usually caused by the opening of chloride channels or the closing of potassium channels. The other choices are associated with excitatory postsynaptic potentials (EPSPs).
