abstract：:The generation of phasic muscle activity during REM sleep is regulated by the brainstem. We proposed two sleep indices for phasic muscle activity during REM sleep, and examine their usefulness in assessing normal brainstem maturation and functional brainstem impairment during infancy. One - the dissociation index (DI)...

abstract：:Four young harp seals (aged three to five months) were implanted with electrodes for recording electrocorticograms (ECoG) of the two hemispheres, and electrocardiogram, electroculogram, and electromyogram of the neck muscles. In all the seals ECoG slow waves developed simultaneously in both hemispheres, irrespective o...

abstract：:A developmentally immature sleep pattern has been identified in infants with a recent history of an unexplained life-threatening episode of sleep apnoea who are considered at risk for SIDS. In these infants there is a persistence of Sleep Onset REM Periods (SOREMPS) after prolonged wakefulness when compared to control...

abstract：:Since rapid eye movement (REM) sleep deprivation has been reported to affect the neuronal excitability in the brain, it was hypothesized that a change in the neuronal membrane-bound Na-K ATPase activity might be at least one of the factors inducing such a change. Therefore, in this study rats were deprived of REM slee...

abstract：:Ponto-geniculo-occipital (PGO) waves are spontaneously-occurring macropotential waveforms recorded in the pons, lateral geniculate body (LGB) and occipital cortex. PGO waves mark the onset and course of rapid eye movement sleep (REM). PGO-like waves can be recorded in several brain areas including the thalamic central...

abstract：:Night sleep in sedentary African subjects living in the sahelian zone lasts from 7 h to 8 h, with high amounts of slow-wave sleep (SWS) and paradoxical sleep (PS), SWS being present in each sleep cycle. We report here on sleep patterns in 6 healthy male European expatriates (aged 32-39 years) living in the same tropic...

abstract：:Activity-rest patterns displayed by an animal under various circumstances are suggested to result from the combined influences of two virtually identical circadian pacemaker components. Increased output of each component proportionally increases the probability of activity of the animal. Such a dual circadian pacemake...

abstract：:The distributions of the durations of the first 3 REM sleep episodes have been analysed using a total of 134 overnight sleep recordings from 10 subjects. From investigation of the length of uninterrupted episodes of stage REM, it is shown that arousals to stage 0/1 could play an important part in the process of REM ex...

The two conditions were repeated the following week in opposite order. Bright light significantly suppressed salivary melatonin and raised rectal temperature 0.3 degrees C (whic...
