美国研究人员发现,长期睡眠不足可能导致脑损伤,事后补觉或亦无济于事。美国宾夕法尼亚大学神经系统研究人员用小白鼠做实验,参照倒班工人的作息时间制定一份睡眠时间表。他们让小白鼠打盹,然后短时间或长时间内弄醒它们。研究人员随后检查这些小白鼠的大脑,尤其是检查一束关联意识和认知功能的神经细胞“蓝斑”。结果发现,这些小白鼠损失了大约25%的神经细胞。 US researchers found that long-term lack of sleep may lead to brain damage, after sleep or helpless. Nervous system researchers at the University of Pennsylvania in the United States used mice to experiment and set a sleep schedule with reference to the work-shift schedule of shift workers. They let the mice snooze and wake them up for a short period of time or for a long time. The researchers then examined the brains of these mice, especially examining a cluster of cognate and cognitive neurons called “blue spots.” The results showed that these mice lost about 25% of the nerve cells.
