Restored motion
Partial lesion prevents brain signals reaching the right leg
4
Brain is now connected to working nerves that control the right leg, allowing the monkey to walk

Computer decodes motor intention and sends instructions to a pulse generator implanted beyond
the lesion

Implant in the motor cortex, the brain's movement centre, records activity and sends the signals wirelessly to computer
