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.
