科学家一直认为,控制人体日常循环的生物钟的周期变化幅度大,这与其它动物不同。指出人体生物钟的循环周期平均为25小时,并随年龄的增长而衰减。这一趋势可以解释为何老年人常常会出现睡眠紊乱。但最近Ｃｚｅｉｓｌｅｒ等发现,大脑中的“节律调节器”驱使人体生物钟以24小... Scientists have long believed that the cycle of the circadian clock, which controls the body’s daily circulation, varies widely, unlike other animals. Pointed out that the circulatory cycle of the human body clock averaged 25 hours, and decay with age. This trend can explain why older people often experience sleep disturbances. However, Czeisler et al recently found that the “rhythm regulator” in the brain drives the circadian body clock to 24 ...
