In anaesthetized cats, the reactions of reticulospinal (RS) neurones were tested to paired stimuli applied at the periphery and in central structures (spinal cord funiculi, the reticular formation). This resulted in depression or disappearance of polysynaptic responses to the electrical testing stimuli. The intensity and duration of depression in the same animal after stimulation of peripheral and central structures was comparable, indicating that the responsible mechanisms act chiefly in the reticular formation itself. Polysynaptic discharges from RS neurones could be evoked from one source even when their responses to frequent stimulation of another source was depressed; this shows that attenuation affects reticular formation neurones before RS neurone level. Interposition of this mechanism between receptors and the RS system is very effective from the functional aspect: when the transmission and processing of a signal which does not bring any new information is minimized, the responses of the efferent RS system are minimized at the same instant.
在麻醉猫中，测试了网状脊髓（RS）神经元对施加于外周和中枢结构（脊髓索、网状结构）的成对刺激的反应。这导致对电测试刺激的多突触反应减弱或消失。在刺激外周和中枢结构后，同一动物中抑制的强度和持续时间相当，表明相关机制主要在网状结构本身起作用。即使RS神经元对另一个来源的频繁刺激的反应受到抑制，也可以从一个来源诱发其多突触放电；这表明衰减在RS神经元水平之前就影响了网状结构神经元。从功能方面来看，在感受器和RS系统之间插入这种机制非常有效：当不携带任何新信息的信号的传递和处理被最小化时，传出RS系统的反应会在同一时刻被最小化。
