Hyperpolarization in the postsynaptic cell is caused by A)excitatory postsynaptic potentials. B)inhibitory postsynaptic potentials. C)movement of K⁺ out of the cell. D)Inhibitory postsynaptic potentials and movement of K⁺ out of the cell are correct.

Question

Quizplus · Accepted Answer

Hyperpolarization in the postsynaptic cell is caused by inhibitory postsynaptic potentials (IPSPs) and the movement of potassium ions (K+) out of the cell. Both processes make the inside of the cell more negative compared to the outside, moving the membrane potential further from the action potential threshold.
