Question

What difference between frist brain and second brain ??

Answer 1

Enteric Nervous System. The enteric nervous system is the portion of our nervous system that stretches across our digestive system (as opposed to your central nervous system or autonomic nervous system). It's known as a “second brain” because has its own reflexes, independent of the brain or spinal cord.

Answer 2

The enteric nervous system (ENS) is known as the "second brain" or the brain in the gut because it can operate independently of the brain and spinal cord, the central nervous system (CNS). It has also been called the "first brain" based on evidence suggesting that the ENS evolved before the CNS.
