During formation of motor conditioned reflexes to time (CRT) in alert rabbits, an increase in the number of neurones with activation and diminution of the number of cells with inhibitory trace activity was revealed when the stimuli were omitted, as compared with conditioned reactions (CR) to actual stimuli pairings, as well as a change in CR and CRT signs, as compared with the sign of cell responses to control tests. The changes were more pronounced in the caudate nucleus and the putamen. In the caudate nucleus and the globus pallidus, the number of cells capable of CRT in omissions of pairings increased as compared with the number of neurones which elaborate CR to actual pairings. Differences in the CR and CRT signs may suggest a difference in mechanisms of consolidation and reproduction of trace processes during elaboration of a motor behavioural act.
在警觉家兔形成对时间的运动条件反射（CRT）过程中，与对实际刺激配对的条件反应（CR）相比，当刺激被省略时，发现具有激活的神经元数量增加，而具有抑制性痕迹活动的细胞数量减少，并且与细胞对对照测试的反应特征相比，CR和CRT特征也发生了变化。这些变化在尾状核和壳核中更为明显。在尾状核和苍白球中，与对实际配对产生CR的神经元数量相比，在配对省略时能够产生CRT的细胞数量增加。CR和CRT特征的差异可能表明在运动行为动作的形成过程中，痕迹过程的巩固和再现机制存在差异。
