Brain chip enables injured rats to control movements

With a futuristic brain patch, brain-injured rats regained the ability to reach out and grab a bit of food. The results, in which a newly created electrical device bypasses a damaged brain area, may ultimately lead to ways to repair damage from stroke, blast injuries and diseases such as Parkinson’s.

The findings, published December 9 in the Proceedings of the National Academy of Sciences, “open the door for new experiments and new ways of approaching brain repair after injury,” says S. Thomas Carmichael of UCLA.
