Introduction

Neurons or nerve cells are the basic functional units of the nervous system. Their main function is to transmit information from the body parts to the brain and vice versa. The transmission of the signal takes place by generating an action potential. The action potential is the term given to the electrical signaling that occurs due to the change in electrical potential when an impulse passes through a neuron. It is different from the membrane potential, which is the difference in the charge created after the unequal distribution of ions on the inside and outside of a cell membrane.
