Question

Quizplus · Accepted Answer

Inhibitory postsynaptic potentials (IPSPs) are characterized by hyperpolarization of the postsynaptic membrane, making it more negative than its resting potential. This makes it less likely for the neuron to fire an action potential, as the threshold for depolarization is increased.
