He had volunteered to be half of an experimental trial of a mind-computer interface (BCI), which connects human neural process to skills.

The instant rising arena, which accommodates main BCI corporations Synchron and Elon Musk’s Neuralink, targets to make exhaust of implants and algorithms to revive lost circulation or dialog and treat neurological problems reminiscent of epilepsy.
