E) increased permeability of the membrane to calcium ions.

Question

Quizplus · Accepted Answer

The binding of an inhibitory neurotransmitter to the postsynaptic receptors results in hyperpolarization of the membrane. This occurs because the ion channels for chloride or potassium open, allowing more of these ions to flow into or out of the cell, respectively. This makes it more difficult for the neuron to reach the threshold for generating an action potential.
