Outline of Final Research Achievements

Resting and task-related magnetic cortical fields were measured by a magnetoencephalographic system (MEG), and inter-cortical connectivity was analyzed in physiological and pathological conditions. Change in neural connectivity during somatosensory, auditory, and motor tasks were calculated using latest methods, dipole distribution and coherence/correlation analyses, in healthy subjects. Pathological neural connectivity was investigated in patients with peripheral neuropathy, such as median nerve neuropathy at the wrist, and in patients with central nervous system. Parkinson’s disease. Present series of study resulted in 11 papers published in international journals. We believe that methods for analyzing inter-cortical connectivity during tasks and at rest have been established during our studies. Our methods could be applied to analysis using clinical electroencephalography recording. Application to clinical examination might be possible.
