Which of these statements regarding neuronal integration is NOT correct?
A)Inhibitory synapses cause postsynaptic hyperpolarization.
B)An inhibitory synapse may result in a postsynaptic sodium channel opening.
C) Inhibitory synapse may result in increased postsynaptic potassium efflux.
D) An excitatory synapse causes depolarization of postsynaptic membranes.

Question

Quizplus · Accepted Answer

Inhibitory synapses cause postsynaptic hyperpolarization through the opening of chloride ion channels or the closing of sodium ion channels. They do not result in the opening of postsynaptic sodium channels, which would cause depolarization.
