When patients had both hands transplanted, their brains reestablished connections much more quickly with the left hand than the right, a team of researchers in France reports.
The sample was small, just two patients, but both had been right-handed before losing their hands, and both followed a pattern of reconnection with their brain that was quicker for the left hand.
The study was reported in Tuesday’s edition of Proceedings of the National Academy of Science.
