The biological functions of sleep have long eluded the medical and research community. In four consecutive issues of AIMS Neuroscience, original and review manuscripts were recently published regarding the mechanisms and function of sleep. These articles highlight the well-timed topic of quantitative sleep markers and cognitive functioning as one of extensive interest within the field of neuros...

PURPOSE/OBJECTIVES To update the state of the science on sleep-wake disturbances in adult patients with cancer, focusing on insomnia in the areas of prevalence, mechanisms and models, measurement, interventions, and implications for practice, health policy, education, and research. DATA SOURCES Published articles, books, book chapters, MEDLINE, CINAHL, and PsycINFO computerized databases. D...

Sleep is pervasive throughout most of the animal kingdom-even jellyfish and honeybees do it. Although the precise function of sleep remains elusive, research increasingly suggests that sleep plays a key role in memory consolidation. Newly formed memories are highly labile and susceptible to interference, and the sleep period offers an optimal window in which memories can be strengthened or modi...

A REVIEW OF SLEEP DISORDERS IN DEPRESSION Summary. Aims. The main aims of this study are, on the one hand, to report on the current state-of-the-art in research into the characteristics of sleep in depression and, on the other hand, to analyse the theoretical and practical implications of these results. Method. We review the main findings regarding the sleep disorders linked with depression and...

Sleep abnormalities are associated with acute and chronic use of addictive substances. Although sleep complaints associated with use and abstinence from addictive substances are widely recognized, familiarity with the underlying sleep abnormalities is often lacking, despite evidence that these sleep abnormalities may be recalcitrant and impede good outcomes. Substantial research has now charact...

Sleep apnoea is a disorder characterised by repetitive pauses in breathing during sleep caused by airway occlusion (obstructive sleep apnoea) or altered control of breathing (central sleep apnoea). In this Clinical Year in Review, we summarise high-impact research from the past year pertaining to management, diagnosis and cardio-metabolic consequences of sleep apnoea.

We would like to thank dr. Begi for his comments and suggestions regarding our paper titled "Polysomnographic sleep patterns in depressive, schizophrenic and healthy subjects" published in Psychiatria Danubina (Ilankovi et al. 2014a). We agree with most of the comments, however, in dr. Begi ’ text we can see that various terms are being used in sleep research. The most common terms must not alw...

Over more than a century of research has established the fact that sleep benefits the retention of memory. In this review we aim to comprehensively cover the field of "sleep and memory" research by providing a historical perspective on concepts and a discussion of more recent key findings. Whereas initial theories posed a passive role for sleep enhancing memories by protecting them from interfe...

This paper reviews the literature on interindividual variability in human sleep parameters, sleepiness, responses to sleep deprivation, and manifestations of sleep disorders. Variability among individuals in sleep/wake biology and behavior is pervasive. The magnitude of such individual differences is often considerable and comparable to the effect sizes of many experimental and clinical interve...

BACKGROUND Sleep difficulty is a common symptom of cannabis withdrawal, but little research has objectively measured sleep or explored the effects of hypnotic medication on sleep during cannabis withdrawal. METHODS Twenty daily cannabis users completed a within-subject crossover study. Participants alternated between periods of ad libitum cannabis use and short-term cannabis abstinence (3 day...
