By stimulating part of the thalamus (shown here in turquoise), researchers were able to help patients with traumatic brain injuries regain some lost mental function.


For people with traumatic brain injuries, cognitive functions like memory, attention and mood regulation can become exceedingly difficult. But “there is no therapy for this kind of problem, even though it’s so prevalent,” says Nicholas Schiff, a neurologist at Weill Cornell Medical College in New York City.
