Summary Introduction
Introduction:
Neurons are the fundamental units of both the brain and the nervous system. They play an important role in the peripheral nervous system and the central nervous system for cellular communication. Neurons or nerve cells communicate with other body cells through synapses. These neurons’ work is unidirectional because they receive and transfer information in one direction only.
