Electropolygraphic reconrding during night sleep were carried out in ten patients with spontaneous nystagmus due to CNS lesions of various etiology. NREM sleep was found to be normal, REM sleep was diminished, while the intermediate stage eas abundantly represented. In some patients with bilateral lesions of the brainstem, REMs were few in number and never clustered; phasin activity of chin muscles during REMs episodesappeared as usual. The nystagmus, which was coarse and sustained during wakefulness with eyes open, and which was only slightly diminished with eyes closed, disappeared at the very onset of sleep and was never seen during NREM sleep.

Abstract
Electropolygraphic reconrding during night sleep were carried out in ten patients with spontaneous nystagmus due to CNS lesions of various etiology. NREM sleep was found to be normal, REM sleep was diminished, while the intermediate stage eas abundantly represented. In some patients with bilateral lesions of the brainstem, REMs were few in number and never clustered; phasin activity of chin muscles during REMs episodesappeared as usual. The nystagmus, which was coarse and sustained during wakefulness with eyes open, and which was only slightly diminished with eyes closed, disappeared at the very onset of sleep and was never seen during NREM sleep. Usaually the nystagmus was also absent during REM sleep with the exception of three cases where nystagmoid jerks were observed during REMs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
