Question

Quizplus · Accepted Answer

Neurons fire in an all-or-none fashion, meaning that they either reach the threshold for firing and generate an action potential or do not reach the threshold and do not fire. This is true for individual neurons, but not necessarily for groups of neurons working together in more complex processes. Choices A, C, and D are all false statements.
