1.本文用单纤维解剖技术研究了大鼠阴囊的温、冷温度感受器。2.温感受器在阴囊温度升高时呈动态活动，在温度恒定时呈静态活动。静态活性/温度曲线呈钟形，最小值在31和45 ℃，峰值在42 ℃。3.冷感受器也表现出动态和静态的反应，以降低温度。在稳定的温度下，来自某些感受器的脉冲以爆发的形式聚集。每次爆发的脉冲数从30摄氏度的零增加到20摄氏度的四个。
1. The technique of single fibre dissection has been used to study the warm and cold thermoreceptors in the rat scrotum. 2. The warm receptors showed dynamic activity during increases of scrotal temperature and static activity when temperature was constant. The static activity/temperature curve was bell‐shaped, with minima at 31 and 45 degrees C and a peak at 42 degrees C. 3. The cold receptors also showed dynamic and static responses to reductions of temperature. At steady temperatures the impulses from some receptors were grouped in bursts. The number of impulses in each burst increased from zero at 30 degrees C to four at 20 degrees C.
