Fractures affect the brain

Swiss scientists have shown that the fracture of his right hand in right-handers concentration of white and gray matter in the brain centers is shifted to the right hemisphere (to the centers, managing healthy, the left hand). The same scientists assume, occurs in fractures of the lower limbs (relevant research they have not carried out).

Specialists of the University of Zurich with MRI scanned the brains of 10 people injured. The first survey was made on the second day after broken limbs , The second - on the sixteenth day of wearing plaster. Trying to adapt to the new realities of the victims had as soon as possible to carry the main burden on the healthy left arm, with which now comes to wash, comb, brush your teeth and so on. Through these actions the concentration of brain substances assigned to musculoskeletal finite center shifted to 10 % to the right side.

Scientists explain this phenomenon of "brain plasticity." Since the motor cortex of the brain controls the left side of his right hand and, respectively, on the contrary, the system of neural structures responsible for his plot, eventually thins. That is, if you carry most of the load on the "auxiliary" of course, but an injured right arm or leg, however, remains constrained in movement, the motor cortex on the right side is sealed.
