TL;DR

The study of signs showed that association between blinking and persistence of the activity of the chin muscles during paradoxical sleep is never encountered, and the possibility that lesions of the locus coeruleus are responsible for this decrease in paradoxicalSleep is discussed.

Abstract

Twenty-three Parkinson patients were recorded during 2 or 3 consecutive nights. Their treatment, if any, was withdrawn for at least 15 days before the first recording session. Some qualitative abnormalities were noticed during each night in 13 of these patients. They consisted in: 1. Repetitive blinking at the beginning of the night when the lights were turned off, persistence of the electromyographic activity of the chin muscles during paradoxical sleep, occurrence of rapid eye movements and blepharospasms during slow wave sleep before the onset of paradoxical sleep episodes, and alpha rhythm during paradoxical sleep. 2. The study of these signs showed that association between blinking and persistence of the activity of the chin muscles during paradoxical sleep is never encountered. 3. The patients with chin muscle activity during paradoxical sleep had a 50% decrease in paradoxical sleep as compared with the group of patients with repetitive blinking. 4. The possibility that lesions of the locus coeruleus are responsible for this decrease in paradoxical sleep is discussed.

Values for sleep induction and sleep maintenance were essentially unaltered by the administration of levodopa, and the clinical implications in terms of evaluating and treating the moderately severe insomnia in parkinsonian patients are described.

The amplitude of delta waves in the aged was reduced, a finding which probably contributed to the lowered amounts of stage 4 sleep, and the latency from sleep onset to the first REM period in the elderly seemed shortened.

The results suggest that PGOW and PGOREM are closely related, but not identical, phenomena, both dependent upon the activity of pacemakers localized in the pons.

The sleep of this group of subjects showed a marked reduction in the amount of EEG defined stage 4 sleep when compared with a group of younger subjects, and the group of older subjects showed an impressive distribution of stage 0 toward the last third of sleep.

It is noteworthy that the late reflex is consistently absent in coma, suppressed but still frequently evoked by shocks of high intensity in stages II to IV of sleep and freed from the suppression in stage REM, which perhaps may imply different “vigilance levels” between coma and sleep and among stages of sleep.

Electroencephalography and Clinical NeurophysiologyBlink reflexes during sleep and wakefulness in man

39 Citations1972E Ferrari, C Messina

Blink reflexes were studied in man during the sleep-wakefulness cycle and in wakefulness in relation to the vigilance level and emotional state to reveal the particular functional situation of the reflex arcs controlling the facial muscles supporting mimetic expression.

The nucleus of Edinger-Westphal — but not the large-celled nuclei of the oculomotor complex — was found to receive abundant nerve fibres which show a massive accumulation of a primary cateholamine, in all probability nor-adrenaline.
