State Measures and Sleep Stages
Psychological Reports, 1983The present study examines the relationship between sleep and mood variables in an aging (50- to 60-yr.-old) sample of 36 males and 39 females. Data from two nights of sleep recordings were correlated with 5 mood scales from the Lorr Mood test administered 1/2 hr. prior to bedtime on the second night. 18 sleep variables were analyzed.

Sleeping Beauties: Shakespeare, Sleep and the Stage
The Cambridge Quarterly, 2006A great deal has been written about dreams in literature and drama, but very little about sleep. Cornelia Parker's 1995 exhibition The Maybe raised questions about the figure of the sleeping woman in visual, verbal and dramatic art. Excluded from the consciousness of the undreaming subject, audiences turn instead to the impact of her physical presence,

Wakefulness (stage W) is characterized by the “alpha” rhythm, so named because it was the first electroencephalogram (EEG) rhythm discovered. Alpha frequency activity is 8–13 cycles/s and may be recorded anywhere in the brain. Alpha rhythm, however, has come to signify the sinusoidal resting rhythm of the occipital cortex.

Effects of lovastatin and pravastatin on sleep efficiency and sleep stages
Clinical Pharmacology and Therapeutics, 1991The effects on sleep of two 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (40 mg lovastatin and 40 mg pravastatin) were evaluated in 12 normal subjects in a double-blind placebo-controlled sleep laboratory study. Subjects were randomly assigned to each of two parallel groups (lovastatin and pravastatin).

Effect of ritanserin on sleep stages and sleep EEG in the rat
European Journal of Pharmacology, 1988Ritanserin (1.0 and 2.5 mg/kg i.p.) was administered to rats before the start, of the light period, and sleep was recorded during the subsequent 12 h. The higher dose reduced sleep in the first 3 h. Both doses caused a more prolonged suppression of REM sleep.

Effects of Sleep and Sleep Stage on Epileptic and Nonepileptic Seizures
Epilepsia, 1997Summary: Purpose: Previous studies of patients with epilepsy and animal models of epilepsy suggest that sleep increases the frequency, duration, and secondary generalization of seizures. This information is, however, incomplete. Methods: We retrospectively examined video‐EEG monitoring reports from our comprehensive epilepsy center.

Plasma Testosterone and Sleep: Relationship to Sleep Stage Variables
Psychosomatic Medicine, 1982A study was performed to determine whether the pattern of secretion of testosterone (T) during the night bears a systematic relationship to the cyclically recurring periods of rapid eye movement (REM) and non-REM (NREM) sleep. In four healthy male volunteers, 10-20 min sampling of plasma for T was carried out through a long indwelling catheter in ...

Sleep stage relations within the sleep cycles of the cat
Brain Research, 1970Abstract In two 24 h recordings from each of 11 cats, sleep was divided into light slow wave sleep (LSWS), deep slow wave sleep (DSWS) and REM sleep. Sleep stage alternation, hourly distribution of sleep stages and correlations of the different sleep stages within the sleep cycles were analysed.

Sleep Stage Deprivation and Total Sleep Loss: Effects On Sleep Behavior
Psychophysiology, 1975ABSTRACTThe combined effects of total sleep loss and the deprivation of stage 4 or stage REM were studied in I two separate experiments. Two full nights or sleep loss preceded stage 4 deprivation or stage REM deprivation in Experiment 1 (N=12); 1 full night of sleep loss followed 3 nights or stage 4 deprivation or stage REM deprivation in Experiment 2 (

Sleep Stage Characteristics of Extended Sleep in Normal Ss
Perceptual and Motor Skills, 1970Although numerous studies have been conducted on sleep deprivation, few have concentrated on sleep extension in normal Ss. The initial invesugauon in this area was concerned with the distribution of REM sleep in Ss instructed to sleep ad lib. (Verdoqe, 1968). However, no control nights were obtained nor was NREM sleep exam~ned In stages. Webb and Agnew
