Locus coeruleus rhythmic stimulation of 40/s frequency and 50-150 micro A current intensity diminished the inhibitory action from flexor reflex afferents on extensor monosynaptic reflexes in anaesthetized decerebellized cats. Such an effect appeared 600 ms after and reached maximum 1500-1700 ms after the locus coeruleus stimulation. The depression of inhibition was maintained during 2-3 s after cessation of the stimulation. No effect was observed when locus coeruleus was stimulated by a single stimulus or by a short high-frequency pulse train of the same current strength. An increase of the stimulation intensity evoked activation of neighbouring structures. The advantages of the rhythmic stimulation for revealing the influences of slow conducting pathways are discussed.
在麻醉去小脑猫中，蓝斑以40次/秒的频率和50 - 150微安的电流强度进行节律性刺激，减弱了屈肌反射传入纤维对伸肌单突触反射的抑制作用。这种效应在蓝斑刺激后600毫秒出现，并在刺激后1500 - 1700毫秒达到最大值。刺激停止后，抑制作用的减弱持续2 - 3秒。当用单个刺激或相同电流强度的短高频脉冲串刺激蓝斑时，未观察到效应。刺激强度增加会引起相邻结构的激活。讨论了节律性刺激在揭示慢传导通路影响方面的优势。
