Abstract
Changes of the mean firing rate of neurons in the posterior hypothalamus on a regional increase or decrease in the midbrain temperature (0.6-2.0 degrees C) and skin temperature (3-5 degrees C) were studied in unanesthetized rabbits. In the posterior hypothalamus, neurons were found which responded both to the midbrain and skin temperature changes. The data suggest that the posterior hypothalamus takes part in the integration of signals from different central and peripheral temperature sensitive agents.
摘要
在未麻醉的家兔中，研究了中脑温度（0.6 - 2.0摄氏度）和皮肤温度（3 - 5摄氏度）局部升高或降低时，下丘脑后部神经元平均放电频率的变化。在下丘脑后部，发现了对中脑和皮肤温度变化均有反应的神经元。这些数据表明，下丘脑后部参与了来自不同中枢和外周温度敏感感受器信号的整合。
