| Outline of Final Research Achievements |
We aimed to clarify the neural mechanisms of fatigue sensation by assessing functional relationships, using magnetoencephalography with high temporal and spatial resolutions, among brain regions related to multiple aspects of fatigue sensation. We focused on the neural mechanisms related to the re-experience of mental and physical fatigue sensation, the making decision to rest in the presence of fatigue, and the prediction of the level of fatigue sensation in the future. Our results showed that the neural mechanisms of the decision to rest in the presence of fatigue and those of the prediction of the future level of fatigue were related to those of the re-experience of fatigue sensation and those of the self-evaluation of the level of fatigue sensation. These findings may help in the understanding of the pathophysiology of fatigue and fatigue-related conditions and/or diseases.
