Scientists Connect Human Brain To Computer Wirelessly For First Time Ever
While traditional BCIs are tethered to users via cables, the new system — called BrainGate — replaces the cords with a small transmitter affixed atop a users' head. The unit then connects to an electrode array implanted in the brain's motor cortex. In a clinical trial, two participants with paralysis used the system to point, click, and type on a standard tablet computer. They both achieved similar typing speeds and point-and-click accuracy as those attained with wired systems.
The researchers say it's the first time a device has transmitted the full spectrum of signals recorded by a sensor in the brain's motor cortex.
