Scientists find two "brains"

In the activity of life, the role of spinal cord is extremely important in addition to the brain. If the brain is likely to become a life command center, then the spinal cord is the unique information exchange channel of the brain and the limbs. However, it is usually not a second large brain called the spinal cord. So, is there a second brain in the human body? It seems that the conclusions of scientists have been unexpected, but the answer is certain.

Professor Mike Gorsund, University of Columbia, was determined by research, and there was a "organizational institution" in the pleats of human gastrointestinal tissue, namely neural cell complex. With the help of a special substance-neurotactor, the integrated body can be independent of the brain work and signal exchange, which can even participate in learning such as learning as the brain. Professor Mike Gorsund has found the Department of Neurotropathology.

Like the brain, providing nutrients for the second brain is a nerve glial cell. The second brain also has its own cell that is responsible for immunization, defending. In addition, the presence of nerve sensors such as blood amazines, glutamate, neuropeptide proteins is also increased to this similarity between the brain.

This so-called second big brain in the human body has its own interesting origin. The ancient cavity organism has an early nervous system, which makes the organism into functionally complicated brains during evolutionary evolution, and the residual part of the early nervous system turns into control of internal organs such as digestive organs, this transformation It can be observed during embryonic development. In the first phase of the embryonic nervous system, the cellular agglomerates first split, and a partially formed a central nervous system, and the other is swim in the embryonic body until it turns into an independent nervous system in the gastrointestinal system, and later with embryonic Development, under special nerve fibers - the system under the role of vagus nerve is established with the central nervous system.

Not long ago, people thought that the intestines were only a muscle tubular body with basic conditions, anyone did not pay attention to its cell structure, quantity and its activities. However, in recent years, scientists have surprisingly found that the number of gastrointestinal cell cells has about 100 million, and the vagulent nerves cannot guarantee the close relationship between the complex system. So how is the gastrointestinal system work? Through the study found that the reason why the gastrointestinal system can work independently, it is that it has its own command - the human body's second brain. The main function of the second brain is to monitor the stomach activity and digestion process, observe food characteristics, regulate digestive speed, speed or slow digestion. It is very interesting that like the brain, the second brain of the human body needs to rest, immersed in the dream. The second brain will have some fluctuations in the intestine when dreaming, such as muscle contraction. In the case of mental stress, the second brain will secrete a special hormone like the brain, which has excessive serotonin. People can experience the state, that is, there is a "cat grasp" feeling, in particular serious cases, such as frightening, the stomach will appear diarrhea. The so-called "frightening butt rising urine" refers to this situation, Russians are called "bears".

The medical community has such a term, namely the nerve stomach, mainly refers to the reaction of the stomach to gastric burning and tracheal spasm. If there is a further poor stimulus factor, the stomach will cause gastritis and gastric ulcer. On the contrary, the activities of the second brain will also affect the activities of the brain. For example, send the dyspepsatic signal to the brain, causing nausea, headache or other uncomfortable feelings. The human body sometimes allergies some substances is the result of the second brain acting on the brain.

Although scientists have discovered the role of the second brain in life activities, there are still many phenomena waiting for further study. Scientists have not figured out what role in the second brain in the process of human thinking, and whether there should be a second brain in the low-grade animal. People believe that one day, the science will make everyone truly cognizes their lives.

To this end, scientists made a call: "Love the stomach! Love your second big brain!"
