Abstract :
The precision of current source estimation of electroencephalography by referring the shape of the brain acquired as MRI was considered. The location of the candidate current dipoles was limited to on the surface of the cortex, and the orientation was constrained to the vertical to the surface. Electric stimulation of median nerve was executed to confirm whether it works appropriately by checking the estimated active area on the cortex
