| Research Abstract |
Higher brain function of human has been thought summation of regional cortical functions in a wide range of the brain. Therefore, decoding of human intention from electrocorticogram (ECoG) would require sampling of the electrical signals over wide range of the brain using grid electrodes. To investigate this hypothesis we conducted studies on brain areas associated with sentence processing using functional MRI and on the neural decoding of single vowels during covert articulation using ECoG. Our study, however, indicated that the discriminative information of ECoG, from which his intention of choice could be extrapolate, would be obtained from very limited number of electrodes on the specific cortical areas.
