“…In summary, performance on behavioural tasks show gradually deteriorate with increasing sleepiness. The close agreement of the EEG NREM 2 and the behavioural criteria marked a decline in behavioural responding during the transition from NREM 1 to NREM 2 ( 110 ) with the associated cessation of behavioural response by NREM 2 ( 111 ). Arguably, the combination of behavioural, physiological and EEG measurements might be taken as suggestive of NREM 2 sleep stage as a cut of point for a true sleep onset, with NREM 1 presenting a diverse landscape of sleep-wake oscillations ( 108 ).…”

Background The sleep onset process is an ill-defined complex process of transition from wakefulness to sleep, characterized by progressive modifications at the subjective, behavioural, cognitive, and physiological levels. To this date, there is no international consensus which could aid a principled characterisation of this process for clinical research purposes. The current review aims to systemise the current knowledge about the underlying mechanisms of the natural heterogeneity of this process. Methods In this systematic review, studies investigating the process of the sleep onset from 1970 to 2022 were identified using electronic database searches of PsychINFO, MEDLINE, and Embase. Results A total of 139 studies were included; 110 studies in healthy participants and 29 studies in participants with sleep disorders. Overall, there is a limited consensus across a body of research about what distinct biomarkers of the sleep onset constitute. Only sparse data exists on the physiology, neurophysiology and behavioural mechanisms of the sleep onset, with majority of studies concentrating on the non-rapid eye movement stage 2 (NREM 2) as a potentially better defined and a more reliable time point that separates sleep from the wake, on the sleep wake continuum. Conclusions The neurophysiologic landscape of sleep onset bears a complex pattern associated with a multitude of behavioural and physiological markers and remains poorly understood. The methodological variation and a heterogenous definition of the wake-sleep transition in various studies to date is understandable, given that sleep onset is a process that has fluctuating and ill-defined boundaries. Nonetheless, the principled characterisation of the sleep onset process is needed which will allow for a greater conceptualisation of the mechanisms underlying this process, further influencing the efficacy of current treatments for sleep disorders.

“…One of the first tasks was to establish the relationship between the monitor and EEG assessments of sleep. Laboratory studies of 3 insomniac and 12 non-insomniac subjects demonstrated that in every individual case, sleep onset, measured by the monitor, corresponded closely and consistently to the first appearance of Stage 2 EEG, w&ch is the accepted conservative criterion of sleep onset (Birrell, 1983).…”

An experimental model for the investigation of the conditions and mechanisms of placebo influences is presented. The model, which is based on the modification of chronic insomnia, was designed to meet seven criteria of ad uacy for the study af placebo. Both subjective (Sleep Diary) and objective (Behaviouralllap Monitor) measures were wd to assess changes in the sleep patterns of insomniacs aged 18-65 years. Over a four-week period, active treatment (cadenced surf-like continuous auditory stimulation) produced continuous and clinically significant objective improvement in s l a p onset latency, duration of wakefulness and total s l a p time.Requests for reprints should be sent to S.
