The organization of sleep after audiogenic paroxysmal seizures of different intensities induced in animals with a normal daily sleep-waking cycle was studied in Krushinskii–Molodkina rats, which have an inherited predisposition to audiogenic convulsions; sleep organization was also studied after 12-h deprivation of fast-wave sleep on a platform or 6-h total sleep deprivation by waking. In all these conditions, intense audiogenic seizures with clonic or clonic-tonic convulsions produced long-lasting and significant disorders of sleep organization in rats, expressed predominantly as impairments to the functional mechanisms triggering the fast-wave phase of sleep. While paroxysmal seizures evoked after experimental sleep deprivation consisted only of motor arousal without any clear signs of convulsions, this type of seizure could even to some extent promote the faster onset of recovery after deprivation and did not induce functional disorganization of the brain system responsible for triggering and maintaining fast-wave sleep.
