暴露于连续光（LL）导致大鼠昼夜节律的自由运行期延长。然而，LL可能并不总是意味着视交叉上核（SCN）的恒定光强度，因为大鼠可以通过在睡眠阶段期间闭合的眼睑来调节照明的对比度。眼睑的去除导致LL下的自由活动期或活动性缩短。此外，在SCN附近植入卡巴胆碱--乙酰胆碱激动剂--也产生了类似的效果。
Exposure to continuous light (LL) results in elongation of the free-running period of the rat circadian rhythm. However, the LL may not always mean constant intensity of light for the suprachiasmatic nucleus (SCN), since rats may regulate contrast of illumination by their eyelids which are closed during sleep phase. The removal of eyelids caused shortening of the free-running period or arrhythmicity under LL. In addition, implantation of carbachol--acetylcholine agonist--near the SCN also resulted in similar effects.
