Fig. 1From: Design-development of an at-home modular brain–computer interface (BCI) platform in a case study of cervical spinal cord injurySystem overview. Electrocotricography (ECoG) signals are recorded using two four-contact subdural strips placed on the surface of the sensorimotor cortex. ECoG signals were transmitted by a subcutaneous implant to an external receiver which delivers it to the minicomputer for processing. The decoder classified the signal as a motor imagery command that is then sent over Bluetooth to actuate the mechanical gloveBack to article page
