Squirrel monkeys (Saimiri sciureus) will learn to regulate their chamber air temperature (Ta) behaviorally by selecting between two air temperatures, 10 and 50 degrees C. When transient (10-min) displacements of local preoptic temperature (Tpo) are made around neutral, via water-perfused thermodes, changes in Ta selected are linear and inversely proportional to the Tpo displacement. The same result occurred in the present study when 10-min Tpo displacements were made around a clamped (36--41 degrees C) Tpo. The higher the clamped Tpo level, the steeper the linear functions relating behavioral response to Tpo transients. This change of gain was manifested in behavioral adjustments of Ta or skin temperature. The data showed that the temperature of the extrahypothalamic body core (measured rectally) was driven by the clamped Tpo to a nonneutral level. When this level was maintained stable during the Tpo transients, core temperature was shown to be a multiplicative factor governing the gain of the behavioral effector responses.
松鼠猴（松鼠猴属）会通过在10摄氏度和50摄氏度这两种气温之间进行选择，学会以行为方式调节其饲养箱内的气温（Ta）。当通过水灌注式热电极使局部视前区温度（Tpo）在中性温度附近产生短暂（10分钟）的位移时，所选择的Ta变化呈线性，且与Tpo位移成反比。在本研究中，当在钳制的（36 - 41摄氏度）Tpo周围进行10分钟的Tpo位移时，也出现了同样的结果。钳制的Tpo水平越高，将行为反应与Tpo瞬变联系起来的线性函数就越陡峭。这种增益变化体现在Ta或皮肤温度的行为调整上。数据表明，下丘脑外体核的温度（通过直肠测量）被钳制的Tpo驱动到一个非中性水平。当在Tpo瞬变期间该水平保持稳定时，核心温度被证明是控制行为效应器反应增益的一个倍增因素。
