Brain implants help paralysed man to walk again




The operation to restore Gert-Jan’s movement was carried out in July 2021. Prof Bloch cut two circular holes on each side of his skull, 5cm in diameter, above the regions of the brain involved in controlling movement. She then inserted two disc-shaped implants which wirelessly transmit brain signals – Gert-Jan’s intentions – to two sensors attached to a helmet on his head.
