Glossary Term

Refractory Period

Refractory period refers to the time immediately following an action potential when the neuron is unable to generate another action potential. This is a critical process that ensures the proper functioning of the nervous system.

Refractory period: cell membrane recovery time immediately following an action potential, during which another action potential is not possible.
