Research Abstract

Sympathetic hyperactivity during rest is induced by fatigue. However, the molecular and neural mechanisms of the relationship between fatigue and change in autonomic function are unclear. The aim of the present study was to clarify the molecular and neural substrates associated with fatigue and autonomic activity in healthy volunteers using functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). We found that decreases in neural activation and serotonergic function of the cingulate gyrus may be associated with the sympathetic hyperactivity in fatigue condition.
