    Notes: Four groups, two comprising three neonatal rhesus monkeys and two comprising two juvenile rhesus monkeys, were selectively deprived of either low-voltage, fast-wave sleep (LVF) or of high-voltage, slow-wave sleep (HVS), respectively. Both infant and juvenile Ss displayed an over-all increase in threshold to the tone-shock combination during the deprivation of either phase of sleep. However, the thresholds of the infant Ss were greater, throughout deprivation, than the thresholds of the juvenile Ss.The juvenile Ss exposed to LVF deprivation were unique in exhibiting a sharp increase in frequency of forced awakenings from LVF, to values significantly greater than for the other groups, and in displaying compensatory recovery effects, manifested by increases in proportion of total sleep time spent in LVF, following termination of deprivation.Behavioral disturbances accompanying deprivation were not evident in any of the experimental groups.The study revealed a number of methodological problems related to the definition and to the selective deprivation of a particular state of sleep.

    AN AUTOMATIC ANALYZER OF STATES OF VIGILANCE (1965)

    Notes: An assemblage of relay-operated, commercially available programming modules is described. It is capable of discriminating among the states of vigilance wakefulness (W): high-voltage, slow-wave sleep (HVS); and low-voltage, fast-wave sleep (LVF) and it requires information from only the nuchal electromyogram (EMG) and the electrooculogram (EOG).

    Performance and Mood Following Variations in the Length and Timing of Sleep (1973)

    Notes: The relative effects of extended sleep, sleep deprivation, and shifts of accustomed sleep time on subsequent performance and mood were studied. Ten regular 2400–0800 sleepers worked on E-paced addition and vigilance tasks, and completed an adjective check list to rate their mood following 2100-0800 extended, 2100-0500 advanced-shift, 2400-0800 habitual, 0300-0800 deprivation, and 0300-1100 delayed-shift conditions of sleep. Accuracy and speed of response on the vigilance task were significantly poorer, and negative affect was significantly greater after the conditions of shifted sleep and altered sleep duration than after the habitual sleep condition. Changes in the mood and performance measures were unrelated to prior sleep length or any specific alterations in the electrophysiological patterns of sleep.

    INCREASED ACCURACY OF BINOCULAR DEPTH PERCEPTION FOLLOWING REM SLEEP PERIODS (1971)

    Notes: It has been proposed that REM sleep maintains facilitation of coordinated eye movements necessary for accurate binocular depth perception (Berger, 1969). This experiment confirmed the prediction that binocular depth perception would be more accurate at the ends of REM periods than at their onsets. Eight male subjects were studied during 4 non-consecutive nights of sleep. Accuracy of binocular and monocular depth perception were measured with different apparatus in the evening prior to sleep onset, after awakenings made alternately at the onsets or ends of REM periods, and 15 min after awakening in the morning. Accuracy of binocular depth perception was significantly better at the ends of REM periods than at their onsets (p 〈 .001), whereas accuracy of monocular depth perception did not significantly differ. That the monocular task was sensitive to variables of sleep was indicated by impairment at the first REM onset with little variation throughout the night, so that it was significantly worse 15 min after morning awakening than the previous evening (p 〈 .05). In contrast, accuracy of binocular depth perception was significantly better in the morning than the previous evening and at REM onsets (p 〈 .05).

    Notes: [Auszug] We have been unable to confirm the findings of Roffwarg et al4, although similar procedures were followed except in the methods of data analysis. In their study one investigator, who had not previously seen the electro-oculographic (EOG) records, mado predictions of the eye movement patterns before ...

    Regulation of body temperature, metabolic rate, and sleep in fasting pigeons diurnally infused with glucose or saline (1991)

    Notes: Summary To test the hypothesis that nocturnal body temperature (Tb) and metabolic rate (MR) in the pigeon are regulated during sleep at levels proportional to energy reserves, continuous recordings of Tb, oxygen consumption ( $$\dot V$$ O2), carbon dioxide production, and electrophysiological measures were taken from five pigeons subjected to two separate 4-day fasts. Energy reserves were depleted differentially during the fasts by 12-h diurnal infusions of either saline or isosmotic glucose solutions. Although Tb and $$\dot V$$ O2 were closely correlated, $$\dot V$$ O2 declined throughout the fast during diurnal and nocturnal phases of the 12:12 light-dark cycle whereas significant declines in Tb were restricted to the night. Diurnal thermal conductance declined over days of fasting, especially during saline infusions, and was reduced to minimal levels each night. The durations and distributions of arousal states did not change during the fast or differ between conditions. The results were consistent with the hypothesis of a nocturnal regulation of Tb and metabolic rate proportional to energy reserves.
