A subject undergoing epilepsy surgery evaluation uses invasive electrocorticogram (ECoG)-based brain-computer interface (BCI) to operate a robot arm in real time. This BCI works as a state machine, detecting periods of idling and movement (wrist flexion/extension). Upon detecting movement, the “wrist” of the robot arm undergoes flexion/extension cycles at a constant frequency.
The study was performed at the UC Irvine Medical Center.
