In chronic experiments on cats, after elaboration of eyelid reflex to clicks, EPs were simultaneously recorded in the auditory, sensorimotor and visual neocortical areas in response to heteromodal paired stimulations with changing interstimuli intervals (click+electro-cutaneous stimulation of m. orbicularia oculi, CS and US). With short interstimuli intervals (up to 50 ms), a stage of sharp EP suppression in the sensorimotor cortex in response to the test electro-cutaneous stimulus was observed. After extinction of the conditioned reflex initial relations were restored: with the same short interstimuli intervals, the EPs to the test electro-cutaneous stimuli were commensurable with those to the isolated application of the current. The data obtained are considered as electrographic sign of the synthetic nature of the conditioned reflex formation.
在对猫进行的慢性实验中，在对咔哒声建立眼睑反射后，针对具有变化的刺激间隔（咔哒声 + 眼轮匝肌的电皮肤刺激，条件刺激和非条件刺激）的异模态配对刺激，同时记录了听觉、感觉运动和视觉新皮层区域的诱发电位。当刺激间隔较短（最长50毫秒）时，观察到在感觉运动皮层中对测试性电皮肤刺激出现诱发电位急剧抑制的阶段。在条件反射消退后，初始关系得以恢复：在相同的短刺激间隔下，对测试性电皮肤刺激的诱发电位与对单独施加电流时的诱发电位相当。所获得的数据被视为条件反射形成的综合性本质的电描记标志。
