研究了4种不同环境温度（Ta）下松鼠猴24 h明暗循环（LD 12:12）下丘脑温度节律及其与结肠温度节律的关系。两种温度节律的波形和相位在所有地区都是相似的。然而，随着Ta的增加，节律幅度减小。在较高的Ta值下，24小时平均值也呈现出系统性的下降。下丘脑温度的调节范围较结肠温度窄，除最暖温度外，其余温度均高于结肠温度。夜间平均气温受Ta的影响大于白天平均气温。下丘脑和结肠的温度节律在昼夜节律调节方面似乎非常相似。这些节律的平均温度水平受到不同的控制。因此，这些节律是昼夜节律和体温调节控制系统的综合反应。
The hypothalamic temperature rhythm and its relationship with the colonic temperature rhythm of squirrel monkeys in 24-h light-dark cycles (LD 12:12) at 4 different ambient temperatures (Ta) was examined. The waveforms and phases of both temperature rhythms were similar in all Ta. The rhythm amplitudes were, however, reduced as Ta increased. The 24-h means also showed systematic decreases at higher Ta. The hypothalamic temperature was regulated over a narrower range than the colonic temperature and was higher than colonic temperature at all Ta except the warmest. The mean nighttime temperatures were influenced more by Ta than were the mean daytime temperatures. The hypothalamic and colonic temperature rhythms appear to be very similar in their circadian regulation. The mean temperature levels of these rhythms are controlled differentially. Thus these rhythms are the integrated response of both the circadian and thermoregulatory control systems.
