Outline of Final Research Achievements

The purpose of this study was to elucidate a physical regulation system in the central nervous system under the condition of fatigue using functional brain imaging techniques from the viewpoint of fatigue, inhibition system, facilitation system, and fatigue sensation. By using magnetoencephalography, neural substrates of inhibition system (dorsolateral prefrontal cortex), facilitation system (dorsolateral prefrontal cortex), and fatigue sensation (posterior cingulate cortex). On the other hand, I proved that the classical conditioning of physical fatigue could take place (posterior cingulate cortex) and identified the neural mechanisms to cause chronic fatigue using the magnetoencephalography.
