| Research Abstract |
Fatigue sensation was attenuated by an intrinsic reward (IR) during a fatigue-inducing tasks. Functional magnetic resonance imaging revealed that the brain regions involved in the IR were ventral striatum (VS) and anterior cingulate cortex (ACC) during the fatigue-inducing tasks. In addition, the activations of the VS and ACC were correlated with motivation score and score for the alleviation of fatigue sensation as derived from a questionnaire, respectively. These results suggest that anti-fatigue effects of intrinsic motivation are associated with the responsiveness of the ACC.
