Direct brain interface enables paralysed man to walk in exoskeleton


Thibault, 30, fell 15m in an accident four years ago injuring his spinal cord.
He was paralysed and spent the next two years in hospital.
Took part in the exoskeleton trial with Clinatec and the University of Grenoble.
He had surgery to place two implants on the surface of the brain.
Implants each have 64 electrodes that cover the parts of the brain that control movement.
Software reads his brainwaves and turns them into instructions for controlling the exoskeleton.
Initially he practised using the brain implants to control a virtual character, or avatar.
Prof Alim-Louis Benabid explains it is not autonomous walking.
He does not have the quick and precise movements not to fall.
System needs to go from thought to movement in under 350 milliseconds otherwise it's difficult to control.

Obviously this is early steps, but with more research and computing power the results could be astounding
