How does the human brain work when it turns from consciousness to unconsciousness?

Psychologists at UCLA used techniques of brain imaging to analyze what happens to the human brain when it turns to unconsciousness. This study is published in the journal PLOS Computational Biology. The lead author of the study is Martin Monti, an assistant professor psychology and neurosurgery at UCLA. There were various participants involved in the research, both men and women, aged between 18 and 31 years who became unconscious after receiving anesthesia. Their brain was imaged by particular techniques that were released by the psychologists. Monti explains that communications becomes totally inefficient in areas of the brain, when people lose consciousness. Monti also states that brain function might be affected by brain injury and it`s difficult to find the exact explanation of this phenomenon. “As profoundly defining of our mind as consciousness is, without having a scientific definition of this phenomenon, it is extremely difficult to study”, Monti noted.
