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 Cl^- enters the postsynaptic cell and increases its permeability to Cl-, the membrane potential becomes more negative. This inhibitory effect moves the membrane potential away from the threshold for an action potential, making it less likely for the neuron to fire.
