Abstract (in Japanese) (See Japanese page) 
(in English) We investigated whether it is possible to detect the intention to move body parts such as fingers by focusing on the high gamma(HG) band SMR（sensory-motor rhythm). Brain activity of subjects were measured by fMRI and EEG during thumb, index and little fingers. We evaluated the differences in fMRI activity by tapping of three fingers, and estimated cortical currents using fMRI, MRI and EEG data, and evaluated the current density distribution in detail. We detected differences in the spatial distribution of HG band SMR produced by different finger tapping, which may facilitate the estimation of body regions.
