The trace recruitment of rhythm (TRR), an analog of the CR to time, which arises in response to prolonged electrodermal stimulation of the forelimb of the awake rabbit at a frequency of 0.5-2 Hz, was studied. The activity of 180 cells of the sensorimotor cortex before (80) and after (100) periodic stimulation for a duration of 10-20 min was recorded. The first series of rhythmical stimulation led to a brief TRR of the stimulation frequency; subsequent series formed a clear TRR which was preserved for several days. The possibility of 'retraining' the neurons given a change in the rhythm of stimulation was identified. The capacity of the TRR phenomenon for extinction, prolonged maintenance, and reproduction of traces, as well as 'retraining' allies it with processes analogous to the temporary connections.
