[Structure of nocturnal sleep in akinesia of many years duration and artificial pulmonary ventilation].

The polygram of night sleep was studied in 4 patients, who due to a lesion to the CNS and peripheral nervous system were in a state of long-term akinesia and artificial lung ventilation. The cyclic organization of sleep and its transition from stage to stage, as a whole corresponded with those in norm. However, there was a deficit of delta-sleep, differently expressed in each patient with a general tendency in all patients to a reduction of sleep spindles. The relationship between delta-sleep spindles and motor activity is discussed.
