How the Neurobridge works
Researchers at Battelle, a large nonprofit research and development organization, have invented a multi-step process meant to help paralyzed people move their hands again with their own thoughts. Read related article.
Surgeons embed a chip with 96 electrodes in the patient’s brain. The electrodes "read" the commands from the part of the brain that controls hand movement.
A wire connects the chip to a port, screwed into the skull. The port connects to a cable that carries the information from the brain chip.
The cable (not shown) links to a computer, where an algorithm "decodes" the brain commands and adds additional commands, which normally would come from the spinal cord.
The computer connects to a "sleeve" of electrodes wrapped around the arm, which fire in a sequence to stimulate muscle fibers, which trigger the movements the patient is thinking of. The whole process lasts less than a tenth of a second.
