大鼠在19小时、24小时或29小时的活动轮中运行至少21天。进食周期。24小时。SS对它们的正常摄食时间表现出通常的“预期”,但一天一天的SS不是这样。相反,他们的活动往往发生在一天中的固定时间,在某些情况下,24小时。在最后一次进食之后。结果表明,车轮运行活动要么受外部的昼夜信号控制,要么受具有自然24小时的“生物钟”控制。期间,但不是由剥夺本身引起的刺激。“(心理信息数据库记录(C)2016 APA,保留所有权利)
" Rats were run for at least 21 days in activity wheels under either 19-hr., 24-hr., or 29-hr. feeding cycles. The 24-hr. Ss showed the usual'anticipation'of their regular feeding hour, but the a-diurnal Ss did not. Instead, their activity tended to occur either at a fixed time of day or, in some cases, 24 hr. after the last feeding. The results suggest that wheel-running activity is controlled either by external diurnal cues or by a'biological clock'with a natural 24-hr. period, but not by stimuli arising from deprivation per se."(PsycINFO Database Record (c) 2016 APA, all rights reserved)
