破解大脑隐性睡眠

Sleep-deprived rats suggest sleep is not necessarily a whole-brain phenomenon.

被剥夺睡眠的老鼠显示,睡眠不必整个大脑休息。

sleepy rat

This rat is not as alert as it looks.Yuval Nir

这只老鼠看起来不那么机警。

The closed eyes, the unresponsiveness, the drool — sleep is an easily recognizable, all-encompassing state. But the divide between sleep and wakefulness may not be as clearcut as we thought.

闭着眼睛、无任何反应、流着口水,这是所有最易辨别的睡眠状态。但是,睡眠与觉醒之间的区别并非我们所想像那么清晰。

Research published today in Nature demonstrates that in visibly awake rats, neurons in some areas of the brain's cortex briefly go 'offline'. In these pockets, neuronal patterns resemble those associated with non-rapid eye movement (NREM) sleep1.

“自然”今天发表的研究文章指出,完全清醒状态下的老鼠,大脑皮层某些神经元有时出现短暂“断开”。这些区域的神经活动模式类似于非快速眼球运动。

"The rats were awake, but awake with a nice sprinkling of localized sleep in the cortex," says Guilio Tononi, a neuroscientist at the University of Wisconsin–Madison and lead author of the study.

“老鼠尽管处在清醒状态,但大脑皮层却有少量局部睡眠。”负责该项研究的美国威斯康星-麦迪逊大学神经科学家朱利奥?托诺尼(Guilio Tononi)如此说。
