Question

Quizplus · Accepted Answer

Depolarization of a neuron membrane involves a shift towards a less negative (more positive) membrane potential. Starting from a resting potential of -66 mV, moving to +45 mV represents a significant depolarization, typically seen during the action potential peak.
