Watch Paralyzed Primates Walk Again Using a Brain-Spine Interface
From: ECN Magazine - 11/12/2016

Using a wireless brain-spinal interface, a team of dedicated neuroengineers
was able to bypass spinal cord injuries in two paralyzed rhesus macaques.

The entire system starts with an implanted chip located in the motor cortex,
the region of the brain where the electrical signals responsible for
coordinating movement originate. A neurosensor records the brain signals and
wirelessly sends the data to a computer. After the computer decodes the
gathered information, it transmits the results to an electrical spinal
stimulator located right above the injured area in both primates. This
stimulation communicates to the nerves in the spine in charge of physical
movement.
