疲劳是现代社会普遍存在的健康问题。疲劳感作为一种促使休息以维持体内平衡的生物警报起着重要作用，因此，澄清与疲劳感相关的神经机制是至关重要的。该研究招募了健康男性志愿者，并表明，当需要基于疲劳水平按下按钮时，在感知疲劳之前通过左侧布罗德曼区（BA）6的脑磁图评估的α波段功率的降低小于当需要自愿按下按钮时感知移动意图之前的α波段功率的降低。此外，与根据疲劳程度按下按钮时的右侧BA 6相比，疲劳感觉前左侧BA 6中α波段功率的降低没有改变。这些结果表明，基于疲劳感知的按钮按压在疲劳感知之前没有准备好。这些发现将促进对与疲劳感等主观感觉相关的神经机制的理解。
Fatigue is a health problem prevalent in modern societies. Fatigue sensation plays an important role as a biological alarm urging rest to maintain homeostasis, and clarifying the neural mechanisms related to fatigue sensations by which we decide to engage in rest is therefore essential. This study enrolled healthy male volunteers and showed that the decrease in alpha-band power as assessed by magnetoencephalography of the left Brodmann’s area (BA) 6 before perception of fatigue when a button-press based on the level of fatigue was required was smaller than that before perception of the intention to move when a voluntary button-press was required. In addition, the decrease of alpha-band power in the left BA 6 before the perception of fatigue was not altered compared with that in the right BA 6 when a button-press based on the level of fatigue was required. These results suggest that the button-press based on the perception of fatigue is not prepared before the perception of fatigue. These findings will advance the understanding of the neural mechanisms related to subjective feelings such as fatigue sensation.
