[Temporal structure of the spike trains of neuronal pairs in the neocortex during calm wakefulness in rabbits].
For revealing the conjugation of impulse activity of simultaneously recorded neurones in the visual and sensorimotor areas of rabbits neocortex, histograms were built of cross- and autocorrelation (CCH and ACH) of their discharges sequences. From successions of discharges of the visual cortex neurones, forming pairs of cells acting in correlation, spikes were singled out conjugated with neuronal discharges in the sensorimotor area, and their ACHs were built. In 77% of cases a resemblance was observed of temporal structure of conjugated discharges and real spike sequences, in 23%--there was no such resemblance. Analysis of conjugated discharges ACHs showed that they appeared predominantly periodically (87% of cases). The number of fragments with periodic discharges frequency within delta-frequency range from 3 to 4 Hz prevailed.
