Background: Mental fatigue is prevalent in modern society. Since mental fatigue causes cognitive impairment and this has been one of the most significant causes of accidents, it is important to understand the neural mechanisms of mental fatigue related to cognitive performance and to develop appropriate methods for evaluating and overcoming mental fatigue. In this study, we quantified the effect of mental fatigue on neural activity and cognitive performance and evaluated the relationship between the change of brain activity and cognitive impairment induced by mental fatigue using magnetoencephalography.
Methods: Thirteen healthy male volunteers participated in this study. They performed mental fatigue-inducing task trials for 30 min. resting state magnetoencephalography measurements and cognitive tasks were performed before and after th.. View More»
