title: [Autocorrelation analysis of background spiking of cortical neurons during learning].
abstract: In defensive conditioning of rabbits to light the pattern of the background spike activity (BSA) in the visual cortex did not change in average as compared to the control. In the sensorimotor cortex the spike activity pattern was changed: the afterdischarge inhibition increased. Cells with a regular component in BSA divided into two groups according to the duration of bursts and of inhibitory pauses in the BSA. In the course of conditionings, the number of neurones with non-random components in BSA in the sensorimotor area did not change, while it decreased in the visual area due to a reduction in number of elements with short groups of discharges.
