“…This is in accordance with the two-process model of sleep regulation (Daan et al, 1984) and empirical data on less complicated sleep/wake patterns (Akerstedt and Gillberg, 1986b;BorbCly et al, 1981;Dijk and Beersma, 1989;Dijk et al, 1987;Dijk et al, 1990Dijk et al, , 1991Gillberg et al, 1991;Knowles et al, 1990). The present analysis demonstrated the simultaneous influences of time awake, prior napping, and prior sleep in the same sleep episode.…”

S U M M A R Y Eight subjects were exposed to a sleep schedule of 8, 4, 2, or 0 h of night sleep (awakening at 07 hours) followed by ad lib sleep from 1100 hours. Stepwise multiple regression analysis showed that SWA per cycle was closely related to the amount of prior waking, the amount of prior napping and the amount of prior sleep in the same sleep episode. The homeostatic 'factor S' of the three-process model of sleep regulation of Folkard and Akerstedt predicted as much of the variance of SWA as did the three prior sleep/wake variables together. It was concluded that SWA is closely related to prior sleep/wake history and follows a course similar to that of recovery of alertness.

“…According to the model, SWA reflects and is responsible for a decline of sleep pressure during sleep, so selective suppression of SWA should result in a delayed wake time. In two experiments (Dijk and Beersma, 1989), this did not happen, although in another (Gillberg et al, 1991), some effects were observed. It has been reported repeatedly that in the rat, total sleep time after sleep deprivation can remain above baseline even though SWA has fallen below baseline (Franken et al, 1991;Schwierin et al, 1999).…”

Quantitative models have been developed to describe salient aspects of human sleep regulation. The two-process model of sleep regulation and the thermoregulatory model of sleep control highlight the interaction between sleep homeostasis and circadian rhythmicity and the association between sleep and temperature regulation, respectively. These models have been successful and inspiring, but continuing progress remains dependent on rigorous testing of some of their basic assumptions. Whereas it has been established that EEG slow-wave activity is a marker of sleep homeostasis, its causal role in regulating the timing of sleep and wakefulness remains to be demonstrated conclusively. Likewise, the causal role of the temperature regulatory system in sleep timing requires further investigation. In both models, many parameters have yet to be associated with specific physiologic processes. This makes it challenging, at least within the framework of these models, to account for interindividual differences or age-related changes in such features as sleep duration and sleep timing, as well as changes in the phase angle between the sleep-wake cycle and accepted markers of the circadian pacemaker, such as the body temperature or melatonin rhythm. Although the models may describe adequately global sleep patterns and their circadian modulation, detailed modeling of the frequent short awakenings from, and the subsequent transitions back to, sleep, as well as the variation of the propensity to awaken across the ultradian non-REM-REM cycle, is not addressed. Incoporation of these aspects of sleep in mathematical models of sleep regulation may further our understanding of a key aspect of sleep regulation, that is, its timing.

“…Webb and Agnew 17 presented compelling evidence that SWS increases as a function of prior waking. 30 The experimental suppression of SWS during an interval corresponding to 90% of the undisturbed episode resulted in an increased accumulation of SWS and an extension of sleep duration. 6 Figure 37-1 (right) illustrates the changes of power density in the two recovery nights relative to the baseline level (100%).…”

Chapter 37with the progression of wakefulness and might represent a marker of Process S. However, in contrast to SWA, theta activity undergoes a marked circadian modulation. Advanced versions of the two-process model were applied to simulate the SWA pattern in a variety of experimental schedules. Other models of sleep regulation have been proposed that are based on changes at the neuronal level or on formal mathematical considerations.Evidence has been accumulating for the existence of a local, use-dependent facet of sleep regulation. In humans and animals a selective unihemispheric regional cortical activation during waking gives rise to a predominant local increase of sleep intensity in the previously activated cortical region as reflected by SWA. The synaptic homeostasis theory has been advanced to account for these effects and their functional significance in the framework of brain plasticity. 432 PART I / Section 5 • Chronobiology
