The musicians displayed a 5 percent increase in the volume of their cerebellum. Musicians are not just born with these differences. Some doctors already use a technique called melodic intonation therapy to encourage singing in stroke patients who are unable to speak, which has sometimes led to recovery of their speech, said University of Texas researcher Lawrence Parsons. He and his colleagues, and an independent research team at McGill University, have discovered that music activates specific cognitive and emotional areas of the brain. They believe music may be used to retrain or activate areas deficient or lost due to neurological disease.
Music is biologically part of human life, just as music is artistically a part of human life.
Thought into Action Telekinesis, on the other hand, is not a routine part of life, but researchers at the California Institute of Technology hope someday to give near telekinetic powers to paralysis patients. They have found that a well-known region in the brain, the posterior parietal cortex, located between the visual and motor areas, appears to act as a kind of middleman, turning mental or visual plans into actions. They have mapped areas relating to movements of the arm and the eye and have worked out their neural codes. He and his colleagues are planning to design prosthetic limbs that respond to these codes. As a first step, they are currently implanting electrodes in the posterior parietal lobes of healthy monkeys and will soon be training them to move an object on a computer screen.
