Novel method of generating sensation using a brain computer interface

Restoring loss of limb function, including sensation, is an important challenge for patients after spinal cord injury, stroke, or limb amputation. In this study, patients already scheduled for surgical implantation for another clinical application had a mini-electrocorticography grid with mECoG bipolar electrodes implanted over the hand area of the primary somatosensory cortex. Then, the area of the brain corresponding to sensations in the hand was systematically stimulated, and the location and description of each sensation were provided by the patient, successfully demonstrating the utility of this novel sensory brain-computer interface (BCI).
