测定大鼠被动回避反应的24 h变化。在24小时内，以4小时间隔对不同组的18只动物进行检测。在所有情况下，在第一次试验后48小时测量保留。试验前，所有动物均在受控条件下圈养14天。被动回避反应有明显的24小时节律，最大和最小效应分别出现在亮相和暗相的中间。
The 24 h variation in the passive avoidance response of rats was measured. Different groups of 18 animals were tested at 4 hourly intervals throughout 24 h. In all cases, retention was measured 48 h after the first trial. All animals were housed under controlled conditions for 14 days before testing. A significant 24-h rhythm in passive avoidance response was found, the maximum and minimum effects being in the middle of the light and dark phases respectively.
