Electrical stimulation of locus coeruleus in anesthetized cats was accompanied by a decrease in the inhibitory action of flexor reflex afferents (FRA) on extensor motoneurons. No changes in excitatory reactions of spinal motoneurons were observed. Microinjections of aspartic acid or chlorpromazine depressed FRA inhibitory action; injection of procaine and noradrenaline potentiated this action. The responses of differente spinal interneurons during activation of locus coeruleus were also studied. A conclusion is made that the inhibitory action of FRA is depressed by coeruleo-spinal influences on the level of the last-order inhibitory interneuron of the FRA system.
对麻醉猫蓝斑进行电刺激时，屈肌反射传入纤维（FRA）对伸肌运动神经元的抑制作用减弱。未观察到脊髓运动神经元兴奋性反应的变化。微量注射天冬氨酸或氯丙嗪可抑制FRA的抑制作用；注射普鲁卡因和去甲肾上腺素可增强此作用。还研究了蓝斑激活过程中不同脊髓中间神经元的反应。得出的结论是，蓝斑-脊髓对FRA系统最后一级抑制性中间神经元水平的影响会抑制FRA的抑制作用。
