[Relation between "rest-activity" behavioral phases and features of the spatial organization of cortical potentials...

The development of experimental neurosis in rabbits led to stable changes in the correlation between behavioural phases in "rest-activity", i.e. some prolongation of active phases and a considerable shortening of rest phases. The analysis of spatio-temporal organization of cortical potentials by comparing successive topograms showed that changes occurred not only in quantitative parameters of rest-activity phases but also in their qualitative characteristics. Thus the depth of the resting states in neurosis lessened and the spatio-temporal cortical potentials' characteristics during the active phases were disorganized. The described shifts in the cortex state probably hindered normal alternation of activity-rest behavioural phases providing for optimal conditions of animals' activity.
