In intact goats the core temperature threshold below which heat production increases with falling core temperature, is inversely related to the temperature of the water bath in which they stand and is therefore assumed to be indicative of the central integration of signals from skin and core temperature receptors. The present study shows that a difference in core temperature thresholds for bath temperatures of 35 degrees C and 40 degrees C persisted after denervation of about two-thirds of the skin of the trunk and limbs. Also, for a given combination of skin and core temperatures, heat production was as great or greater after cutaneous denervation as before. It is concluded that, following denervation of the trunk and upper limbs, intact temperature receptors in the non-denervated skin of the legs and tail, and/or also in tissues between the skin and core, provide important and significant inputs to the temperature regulating system. But these inputs cannot explain fully the thermoregulatory responses observed unless it is assumed that the thermosensitivity of these tissues increased.
在完整的山羊中，核心温度阈值（低于此阈值时，产热会随着核心温度下降而增加）与它们所站立的水浴温度呈负相关，因此被认为是皮肤和核心温度感受器信号中枢整合的指标。本研究表明，在躯干和四肢约三分之二的皮肤去神经支配后，35摄氏度和40摄氏度水浴温度下的核心温度阈值差异仍然存在。此外，对于给定的皮肤和核心温度组合，皮肤去神经支配后的产热与之前一样多或更多。得出的结论是，在躯干和上肢去神经支配后，腿部和尾部未去神经支配皮肤中的完整温度感受器，和/或皮肤与核心之间组织中的完整温度感受器，会向温度调节系统提供重要且显著的输入。但除非假设这些组织的热敏性增加，否则这些输入无法完全解释所观察到的体温调节反应。
