Firing beams of light at the part of the brain that controls movement may improve recovery after a stroke according to researchers from Stanford University. Doctors say their research could help explain how the brain recovers and lead to new treatments. The research team investigated whether brain stimulation aided recovery in animal experiments and used a technique called optogenetics to stimulate just the neurons in the motor cortex. After seven days of stimulation the researchers said the mice were able to walk further down a rotating rod than mice which had not had brain stimulation. After 10 days they were also moving faster.
