A graph of an EPSP would plot time against a voltage trace that would resemble
A) a hill where the high point approaches the threshold value.
B) a hill where the high point is the farthest away from the threshold value.
C) a valley where the low point approaches the threshold value.
D) a valley where the low point is the farthest away from the threshold value.

Quizplus · Accepted Answer

An EPSP (excitatory postsynaptic potential) is a temporary increase in postsynaptic membrane potential, making it more likely to reach the threshold for an action potential. This would resemble a hill where the high point approaches the threshold value.
