因为一股涌上大脑的血流,你的大脑将获得更多的氧气与营养物质。(这儿没有酷玩乐队的歌迷吧?真的么?)由于睡眠时大脑是身体内唯一满负荷运作的部分,所以仍在被泵出的的血液便转移到了那里。这便为颅腔内所有的维护功能供能。
4. LAST CALL... FOR MONOAMINE NEUROTRANSMITTERS
4. 最后……是单胺类神经递质
The neurotransmitters norepinephrine, serotonin and histamine are kind of like the cocaine, molly, and PCP of your brain -- respectively. They do a lot of important things when you're awake like sharpen your senses, make you feel good, and help regulate the immune system. During REM Sleep, all three of these neurotransmitters are switched off. Your brain is denied access to all three of them in favor of acetylcholine, which activates muscles and movement. The release of acetylcholine is thought to speed up brain waves -- maybe.
去甲肾上腺素、血清素、组胺这些神经递质依次和可卡因、莫利、PCP有些相像。它们在你清醒时起着重要作用,如使感觉更敏锐、提升愉悦感,并且可以帮助调节免疫系统。在快速眼动睡眠过程中,这三种神经递质全部被抑制了。你的大脑拒绝接受这三者,反而更愿意接受乙酰胆碱,它可以活跃肌肉与行为。乙酰胆碱的释放被认为会加速脑电波--但谁也不好说。
