title: [The dynamics of the electrical activity of the forebrain structures in rats in the waking-sleep cycle after electrostimulations of the emotiogenic zones in the lateral hypothalamic area].
abstract: One series of ES (multiple priming) of emotion-positive zone (1) ore the ambivalent zone (2) of lateral hypothalamus (LH) during one hour in Wistar male rats resulted in disorders of the W-S cycle: reduction of deep slow-wave sleep down to about 4.7% (zone 1) and down to 0.9% (zone 2), as well as a considerable reduction of REM sleep down to 0.8% (zone 1). The results of the analysis of bioelectrical brain activity dynamics in the W-S cycle suggest that hyperactivation of emotiogenic zones generated by ES is responsible for the establishment of paroxysmal states corresponding to the second and the third stages of kindling and the disorders of the W-S cycle. Kindling is assumed to form due to emotiogenic zones of the brain involved in to this process. The longer bursts of hypersynchronous bioelectrical activity in the cortex than in the subcortical structures during transient stages of sleep may be in favour of more active participation of phylogenetically younger brain structures in the process of epileptogenesis.
