Question

Quizplus · Accepted Answer

The brief reversal of the electric gradient across a neuron's plasma membrane is called an action potential. This occurs when the membrane potential reaches a certain threshold, causing the opening of voltage-gated ion channels and a rapid depolarization followed by repolarization. The resting potential is the electric gradient when the neuron is not firing. Kinetic potential and energy potential are not terms used in neuroscience. The threshold potential is the specific membrane potential at which action potential fires, implying that it is part of the action potential process.
