科学家相信他们发现了为什么我们需要睡眠的原因：帮助补充脑细胞。研究结果发表在《Neuroscience》期刊上。他们发现，至少就老鼠而言，睡眠能增加制造髓磷脂的细胞产生率，髓磷脂被用于保护大脑回路不受干扰。细胞增长最快的阶段发生在快速眼动睡眠期间——也就是与做梦有关，受到了基因的控制。如果老鼠被迫保持清醒，与细胞死亡和压力反应相关的基因将会激活。人人都需要7到8小时不受干扰的睡眠。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
