New research suggests that patients whose mobility has been limited by stroke may one day use their imagination and a computer link to move their hands. In patients, scientists at Washington University School of Medicine in St. Louis have shown they can detect the brain simply thinking about moving a partially or completely paralyzed hand. The half of the brain that normally thinks such thoughts and moves the hand can no longer do so because of stroke damage. Instead, the signal comes from the undamaged half of the brain.

Researchers have long been interested in discovering the ways that human brains represent thoughts through a complex interplay of electrical signals.  Recent improvements in brain recording and statistical methods have given researchers unprecedented insight into the physical processes underlying thoughts.  For example, researchers have begun to show that it is possible to use brain recordings to reconstruct aspects of an image or movie clip someone is viewing, a sound someone is hearing or even the text someone is reading.
