German physicists and neuroscientists have come to grips with the study of the human mind, writes information portal rosregistr.ru. To do this, they created a mathematical model that would better know this uncharted area to learn how to behave brain during wakefulness and sleep.
Researchers at the German Institute of Medical Psychology at the University of Kiel conducted a study , participants were twelve. To begin to track brain activity during sleep, they were put sleeping pills. Then, using magnetic resonance imaging scientists monitored brain. similar studies were conducted, and while awake people.
Scientists have found out that the conscious brain uses all the zones and structure – at the time they are combined into a whole system. In the unconscious or dream state, some areas of the brain turns off, and the rest are working in isolation.
Consciousness as established researchers, there is a critical point, when the brain is in a “balanced chaos.” Then the brain actively uses all the structure of the nervous system and coordinates their interaction.
A mathematical analysis has shown that consciousness is a product of “balanced chaos.” During the waking brain behaves actively. He makes the most of all their zones and structure, combining them into a single system. And during anesthesia-induced sleep immersed in “low status” and not everyone uses the structure.
The scientists said the existence of a range of activities. In their view, consciousness arises and there is a critical point – the moment “balanced chaos” when the brain uses all the resources of the nervous system and successfully coordinate their interaction.
The excess of this threshold leads to mental disorders, and on lowering a person faints. The data obtained will be used to develop a new method of therapy for the withdrawal of patients from the state of coma.
The researchers noted that, having reached a “critical point”, one senses the resulting analyzes information, using all parts of the brain. The unconscious man is also able to accept incoming information, but can not analyze it at the same level.
Thus, consciousness involves an “optimal” activity of the nervous system in which the processes in the brain occur as quickly as possible, but remains “under control”. In this respect, it can be called “controlled chaos”, say experts.
The researchers hope their work, published in the edition of The Journal of the Royal Society Interface, to better understand the nature of consciousness that in the future, to example, can help lift people out of the coma.
