Perennial class change ability balerin



Ballet dancers - not just gifted people: study found significant differences in the structure of their brain that prevent feeling dizzy during these endless pirouettes. This means that years of training have developed a ballerina "superpowers": blocking signals from the balance organs in the inner ear, because they might fall.

The findings, published in the journal "Brain» («Cerebral Cortex»), can help in the treatment of patients with chronic dizziness, occurring in one out of four Britons at some point in their lives.

As a rule, the sense of vertigo associated with vestibular organs in the inner ear - the fluid-filled chamber feel the rotation of the head through the tiny hairs, sensing the movement of fluids. If you turn your head too fast, fluid continues to move for some time, that makes you feel as if you are still turn around.

Dancers can also perform several sharp turns without feeling dizzy. The survey results show that they are in the process of training learn to fix his eyes on the same point as long as possible.

Brain scans reveal differences between dancers and ordinary people in the two parts of the brain: the cerebellum, where it is processed sensory information from the bodies of balance, and the cerebral cortex responsible for the perception of dizziness. This area in the cerebellum of the dancers was much smaller.



Dr. Barry Simungal from the Medical Department considers that ballerinas do not listen to the signals your vestibular system, relying instead on a coordinated waste movement. Their brain has adapted over the years of training, therefore, the signal coming from the area of ​​the cerebral cortex responsible for the perception of dizziness, less intense.
