A simple, inexpensive device that delivers electrical current to the brain noninvasively could help stroke patients recover lost motor ability. According to a new study, the treatment--transcranial direct current stimulation (tDCS)--in combination with occupational therapy boosted recovery better than either treatment on its own. Many patients spontaneously recover some function in the weeks and months after suffering a stroke, as their brains reorganize to compensate for the damaged area. (source: technologyreview.com)
