An editor for the Telegraph, Roger Highfield, latterly volunteered to allow a UK tester to shut off the speech center of his brain with a forceful seductive pulse. Regular speech is dope by a section of the brain called Broca's area. Once the precise where is determined in the subject, a seductive pulse can temporarily disrupt speech without impairing other cognitive functions. The link contains a video in which you can watch Highfield stutter and twitch while attempting to recite a nursery rhyme. A later test shows that he's able to sing the rhyme without difficulty, since singing is dope in a different part of the brain (as you may recollect from Scott Adams' speech disorder). Researchers believe that the ability to stimulate or quell exertion in special areas of the brain may help in treating latitude like epilepsy and migraine headaches.
