The effect of heating and cooling in the midbrain on the unit activities of midbrain raphe neurons in the rat was observed. Out of 24 raphe units studied, 14 units responded to a rise in midbrain temperature with an increased rate of firing. The remaining 10 units did not respond to temperature changes between 34 and 41 degrees C. The result is consistent with the idea that the heat-induced increase in brain serotonin turnover is mediated by an increased firing rate of midbrain raphe neurons.
观察了中脑加热和冷却对大鼠中脑缝际神经元单位活动的影响。在所研究的24个缝际单位中，14个单位对中脑温度升高有放电频率增加的反应。其余10个单位对34至41摄氏度之间的温度变化无反应。该结果与热诱导脑内5-羟色胺周转增加是由中脑缝际神经元放电频率增加介导的观点一致。
