The Inner Body as a Source of Temperature Signals
Even small displacements of body core temperature (Tcore) from its normal level induce large effector responses. Figure 3.1 shows data of experiments in a goat. To dissociate skin temperature (Tskin) from Tcore, the animal was immersed to the neck in a rapidly circulating water bath which clamped Tskin at water tem perature. Heat exchangers in an arteriovenous shunt were used to manipulate the temperature of the blood, and indirectly the temperature of all core organs and tis sues except the skin. Thus, Fig. 3.1 presents responses to pure changes in Tcore at constant Tskin.
