An Implanted Array Gives a Paralysed Person Continuous Cursor Control
BrainGate showed that movement intentions could be decoded from motor-cortex neurons years after paralysis and converted into real-time computer control.
A 100-electrode sensor recorded neural spikes from the motor cortex and translated them into cursor and device commands. The result demonstrated high-bandwidth intracortical control in a human, but the experimental system required surgery, cables, calibration and technical support.
