In the intestine is a system, which consists of millions of neurons and autonomic control of the gastrointestinal tract.
In the human body is the “second brain” that resides in the intestines, and Australian scientists were able to understand the principle of its work, writes the online edition of the Chronicle.info with reference to the Correspondent.
Enteric (intestinal − ed.), nervous system (ENS) consists of millions of neurons that govern the gastrointestinal tract. The system and peripheral operates independently from the Central (CNS) consisting of brain and spinal cord.
“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.
According to scientists, a unique feature of the gastrointestinal tract lies in the fact that he is the only internal organ with its own nervous system which can fully function independently of the brain and spinal cord.
Experts analyzed the electrical impulses in the neurons of the colon of mice and found that Enns synchronously activates excitatory and inhibitory neurons, which trigger muscle contraction in the intestines.
According to the study authors, earlier science was not known that millions of cells Enns simultaneously generate electrical impulses.
