Changes in the firing rate of 260 posterior hypothalamic neurons were investigated in experiments on unanesthetized rabbits. In the animals in the initial state the temperature of the posterior hypothalamus was 39.1 +/- 0.02 degrees C, the temperature of the nasal spine was 33.0 +/- 0.02 degrees C, and the skin temperature on the concha auriculae was 30.1 +/- 0.3 degrees C, values which correspond on the whole to those in the thermoneutral zone for the rabbit. During a local increase (by 0.6-1.5 degrees C) or decrease (by 0.6-2 degrees C) in temperature of this region of the brain about 28% of responding neurons were found; most of them changed their firing rate when the brain temperature reached a certain level for each neuron. The threshold varied from 0.6 to 1.0 degrees C from the level of the brain temperature in the thermoneutral zone.
在未麻醉的家兔实验中，对260个下丘脑后部神经元的放电频率变化进行了研究。处于初始状态的动物，下丘脑后部温度为39.1±0.02℃，鼻棘温度为33.0±0.02℃，耳廓皮肤温度为30.1±0.3℃，这些数值总体上与家兔热中性区的数值相符。当该脑区温度局部升高（0.6 - 1.5℃）或降低（0.6 - 2℃）时，发现约28%的反应神经元；其中大多数神经元在脑温达到每个神经元特定水平时改变其放电频率。阈值比热中性区脑温水平高0.6至1.0℃。
