Development of cortical-based neuroprosthetics relies on the ability to decode the direction of an intended motor-movement. The use of a standard ElectroCortical Grid (ECoG) has shown limited success in decoding human reach tasks. The quality of the decode may have sufferd due to amount of cortical area covered by the size of a standard ECOG electrode. A relatively new device called the Utah micro ElectroCortical Grid (UmECoG) has been developed to deal with the spatial issue by using a smaller recording area and a larger number of contacts per square milimeter. Two UmECoGs were implanted in a patient’s motor cortex, above arm and hand areas, while the patient was undergoing epileptic foci locilization. The patient performed reach tasks, and the neural data was correlated to arm and hand movements.
