[Cooperative activity of adjacent visual cortex neurons in alert cats].
By means of auto- and crosscorrelation analysis, background activity of neighbouring neurones was studied in the visual cortex of alert cats. Four types of units differing in spike activity were found; each cortical microarea could consist of neurones of one or of different types. Analysis of configuration of mutual correlation histograms revealed four types of interdependent relations between the neighbouring neurones; definite types of spike activity of individual neurones were characteristic for each type of relations. Study of microsystems in which all or part of the neurones were united by the activity of a "common source" led to the assumption that the source was located outside the microsystems.
