Meditation slows down the operation of the neural network of the brain responsible for self-awareness and self-examination, and it will protect the mind from dangerous dive into the maze of his own "I", which is typical for a variety of mental disorders from autism to schizophrenia.
Meditation helps a person to relax mentally and feel one with the world. At the same time, according to researchers at Yale (U.S.), it can serve as prevention of a number of neuropsychiatric disorders. Using fMRI, scientists monitored the brain activity of several volunteers, as long practice of meditation, and beginners.
It turned out that meditating for a long time in the brain suppresses the activity of the so-called default. Previously believed that this neural network is just noise resting, inactive brain, but later it was shown that it is responsible for introspection. "Who am I", "Why did I do that?", "What would you do if? .." — About such matters are the responsibility "of default" neural network. She harbors dreams and dreams, but it is rooted in it, anxiety, distraction of attention, irritability and nervousness behavior. Moreover, the neurons of the network more than others susceptible to the formation of amyloid plaques in Alzheimer's disease.
In meditating activity of this neural system weakens. The researchers were able to identify on work of the middle zone of the prefrontal cortex and the posterior cingulate cortex. The experiment was attended by people who have three different methods of meditation, but the suppression of "samoanaliziruyuschey" neural activity manifested irrespective of the method of meditation. In addition, meditators simultaneously with this work activity areas of the brain, asking cognitive control — as if consciousness, do not expose itself to dive too deeply into his own "I". There is no need to remind you that it is a dive loop on itself is the basis of autism and schizophrenia.
Results of experiments, scientists are going to publish in the journal PNAS.
Incidentally, the test subject with a lot of experience of meditation does not have to specifically dive into this state, even if they did not do anything mentioned neural activity would not appear in full force. The researchers believe that the practice of meditation successful way balanced by samoanaliticheskoy activity of our consciousness, making it all the time aware of the current situation, connecting it with the outside world.
