Summary Introduction
Introduction:
Neurons are the primary functional units of the nervous system. There are a billion of neurons in the body, which are connected with each other in small groups and are known as neuronal pools. A neural circuit is described as the connection patterns formed by a neuronal pool. The neural circuit works in five different ways: divergence, convergence, reverberation, serial processing, and parallel processing.
