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.

Scientists have made strides in brain-machine interface technology (SN: 11/16/13, p. 22), which routes brain signals to external machines
