In two conscious goats with chronically implanted multithermodes the distribution of thermosensitive sites within the anterior hypothalamus was determined. Changes in heat production at Ta=+5 degrees C and changes in respiratory evaporative heat loss at Ta=+33 degrees C in response to discrete temperature stimuli were measured and the magnitude of the responses was correlated with the histologically assessed position of the probes transmitting the stimuli. In both animals the array of probes was centered close to the center of the thermosensitive area. The density of thermosensitive structures increased toward the center of the area covered by the probes. The most sensitive points were situated close to either side of the midline in those frontal planes which contained the nuclei supraoptici and paraventriculares. No difference was found between cold- and warm-sensitive sites.
在两只长期植入多温度模式的清醒山羊中，确定了下丘脑前部热敏位点的分布。测量了在Ta = +5摄氏度时产热的变化以及在Ta = +33摄氏度时对离散温度刺激的呼吸蒸发散热变化，并将反应幅度与传递刺激的探针的组织学评估位置相关联。在两只动物中，探针阵列都集中在热敏区域的中心附近。热敏结构的密度朝着探针覆盖区域的中心增加。最敏感的点位于包含视上核和室旁核的额平面中线两侧附近。冷敏位点和温敏位点之间未发现差异。
