Australian Scientist have found an autonomic control system similar to brain in gastrointestinal tract.
According to scientists, a unique feature of the gastrointestinal tract lies in the fact. The only internal organ with its own nervous system which can fully function independently of the brain and spinal cord.
Enteric nervous system
Enteric nervous system (ENS) consists of millions of neurons that govern the gastrointestinal tract. However, the system and peripheral operates independently from the Central (CNS) consisting of brain and spinal cord.
Moreover, experts analyzed the electrical impulses in the neurons of the colon of mice. They found that Enns synchronously activates excitatory and inhibitory neurons. As it trigger muscle contraction in the intestines.
Meanwhile, In the human body is the “second brain” that resides in the intestines, and known how it works.
“It’s actually himself the brain,” said Professor Flinders University Nick Spencer, adding that the ENS can be called the “first brain”, since it appeared before the Central nervous system in the course of evolution.
