Increased permeability of the postsynaptic cell to Cl^- lessens the likelihood that the postsynaptic cell will undergo an action potential because the membrane potential is moved farther away from threshold.

Question

Quizplus · Accepted Answer

When the postsynaptic cell becomes more permeable to Cl-, this ion enters the cell and makes the interior more negative (hyperpolarization), moving the membrane potential farther away from threshold and making it less likely to reach the threshold for an action potential.
