One possible treatment for people with neurological problems ranging from brain trauma to multiple sclerosis may lie on the tip of the tongue.
In experiments at the University of Wisconsin-Madison, neuroscientist Yuri Danilov and his colleagues have been studying for the past several years how electrical stimulation of the tongue can bring about dramatic improvements in people whose ability to balance, walk and stand has been damaged in ways that leave them virtually helpless without a walker or crutches.
Two major nerves - trigeminal nerve and cranial nerve - lie in the tip of the tongue. They wend their way to the back of the skull into the brain stem, which essentially performs a lot of unglamorous but essential housekeeping work, such as keeping us breathing, conscious, and our digestive system operating.
