A tracking procedure was used to investigate the ability of rats to regulate their ambient temperature. Rats were placed in a chamber with two levers; depressions of one lever controlled a cold-water flow (11 degrees C) and the other controlled the flow of hot water (57 +/- 1 degrees C). If it alternated responses, the rat could regulate temperature within these two extremes. With training, this regulatory behavior resulted in a narrow environmental temperature range that approximated normal body temperature.
采用一种追踪程序来研究大鼠调节环境温度的能力。将大鼠置于一个带有两个杠杆的小室中；按下一个杠杆可控制冷水流（11摄氏度），按下另一个杠杆可控制热水流（57±1摄氏度）。如果大鼠交替按下杠杆，就能在这两个极端温度之间调节体温。通过训练，这种调节行为使环境温度范围变窄，接近正常体温。
