将金仓鼠（Mesocricetus auratus）置于光暗循环中（LD 14：10）。在2周内，几乎每天都将它们放置在新颖的转轮中3小时，从天黑前7小时开始。大多数动物在这3小时内进行了数千轮旋转。当这些动物随后被转移到暗室时，它们的活动被分成两个部分，一个接近于先前暴露于新轮的时间，另一个接近于它们在先前LD循环的黑暗阶段中活动的时间。在黑暗中几天后，这两个部件融合在一起。这些观察结果表明，nonphotic事件能够引起重大重组的昼夜活动模式，尽管存在的LD周期。
Golden hamsters (Mesocricetus auratus) were kept in a light-dark cycle (LD 14:10). For 2 weeks, almost every day they were placed in a novel running wheel for 3 hr, starting 7 hr before dark onset. Most of the animals made several thousand wheel revolutions during this 3 hr. When these animals were subsequently transferred to a dark room, their activity was split into two components, one close to the time of the previous exposure to the novel wheel and the other close to the time when they had been active in the dark phase of the previous LD cycle. The two components fused after a few days in darkness. These observations show that nonphotic events are capable of causing major reorganizations of circadian activity patterns, despite the presence of an LD cycle.
