摘　　要：我们之所以会整天感到疲劳是因为一种叫做腺苷的神经化学物质在体内积累并和腺苷受体结合,导致神经细胞变得不活跃,大脑血管扩张。简而言之,你的身体会接收到休息的信号。The reason we get tired throughout the day is because a neurochemical called adenosine builds up and passesthrough receptors,which causes nerve cells to become less active and blood vessels in your brain to dilate.

关 键 词：脑血管扩张 腺苷受体 神经细胞 神经化学物质
