A change in the resting potential of a dendrite from -70 mV to -72 mV is called
A) an IPSP.
B) an EPSP.
C) a depolarization.
D) both A and C
E) both B and C

Question

Quizplus · Accepted Answer

A change in the resting potential from -70 mV to -72 mV is a hyperpolarization, which makes it an inhibitory postsynaptic potential (IPSP). Choice B is incorrect because an EPSP would be a depolarization, which is opposite to what is happening. Choice C is incorrect because a depolarization would mean a change in the resting potential in the positive direction, not negative as in the scenario described. Choice D and E are also incorrect because they combine correct and incorrect statements.
