Blind people are often more acute hearing. U.S. researchers found that patients who had lost his sight in childhood, responsible for the use of the area of the brain to hear better, according to the Journal of Neuroscience. In healthy people, the visual cortex and visual function over time - is responsible for the hearing. In case of loss of the occipital region acquires new functions, carried out a study from researchers at the University of Oregon Medical Sciences (Oregon Health & Science University). Study leader Alexander Stephens (Alexander Stevens) blind patients different melodies, each lost by a short beep ahead. At the same time, the brain scans of the participants. It was found that each activity was accompanied by a warning signal in the visual cortex, increased susceptibility to subsequent sounds. Thus blind people summarized the area that is used for the perception of images, in preparation for the perception of sound, the researchers said.

Revealed the secret of optimism
Scientists have found the brain region that is the optimistic view of reality. Opening managed to do it with the functional magnetic resonance imaging. It turned out to be that for the positive thoughts and dreams meet the anterior part of the midbrain. The area is located deep behind the eyes, and activated when people begin to think of a nice future. In the optimistic people activating its clearest expression. The same part of the brain seem to work for those who suffer from depression. A functional magnetic resonance imaging showed that when the thoughts of the future were pleasantly given area of the brain and the amygdala, responsible for emotional responses, including increased anxiety and fear.
