Thermal stimuli were applied to the upper surface of the tongue of the cat. The stimuli ranged from 40 degrees C to 10 degrees C and were changed in cold steps of 5 degrees C, each temperature lasting 2 min. Afferent impulses of single specific cold fibers from the lingual nerve were analysed by a computer program. About 90% of the fibers showed bursts under static conditions. The bursts began as doublets at the temperature of maximal average frequency. This temperature varied from 40 degrees C to 15 degrees C in different fibers, the average being 30 degrees C. The parameters burst period, burst duration, pause duration, intraburst interval and spikes per burst increased monotonically from 30 degrees C to 15 degrees C. The possible physiological significance of the burst pattern is discussed.
对猫舌的上表面施加热刺激。刺激温度范围为40摄氏度至10摄氏度,以5摄氏度的冷阶跃变化,每个温度持续2分钟。通过计算机程序分析来自舌神经的单个特定冷纤维的传入冲动。约90%的纤维在静态条件下出现爆发式放电。爆发式放电在平均频率最高的温度下以双峰形式开始。不同纤维的这个温度在40摄氏度至15摄氏度之间变化,平均为30摄氏度。爆发周期、爆发持续时间、暂停持续时间、爆发内间隔和每次爆发的尖峰数等参数从30摄氏度至15摄氏度单调增加。讨论了爆发式放电模式可能的生理意义。
