| Outline of Final Research Achievements |
I studied the cognitive information processes corresponding to the somatosensory imagery, which is the imagination of sense without real stimulation. I recorded the human brain activity using the magnetoencephalography (MEG), and evaluated the functional connectivity among somatosensory related areas, not the local brain activity itself. From the first result, I identified the region of interests (ROIs) corresponding to somatosensory information processes and found the analysis method to evaluate the functional connectivity, i.e. the Phase-locking value (PLV). The second result revealed that there was a difference in the functional connectivity during somatosensory imagery between right and left hemispheres. To execute the somatosensory imagery needed the functional connectivity between spatially separated brain regions. I considered this results showed that some kind of cognitive processes worked to execute the somatosensory imagery. This result was reported at domestic meeting.
