Genetic and Environmental Influences on Sleep Quality: Quantitative and Molecular Genetic Approaches to an Understanding of Individual Differences [PDF]

open access: yes
There are vast inter-individual differences in sleep quality in the general population – whilst some individuals sleep well with little or no sleep disturbance, others experience frequent sleep disturbances, problems which often manifest into chronic ...

Role of Sleep Restriction in Daily Rhythms of Expression of Hypothalamic Core Clock Genes in Mice

open access: yesCurrent Issues in Molecular Biology, 2022
Lack of sleep time is a menace to modern people, and it leads to chronic diseases and mental illnesses. Circadian processes control sleep, but little is known about how sleep affects the circadian system.

Circadian and ultradian NREM-REM sleep modulation of dream recall : effects of age and spectral activity [PDF]

open access: yes, 2011
This thesis deals with the electrophysiological correlates of sleep prior to dream recall and the age-related effects on dream processing. The dual NREM/REM sleep cycle and the circadian modulation of REM sleep sum to generate dream processing.

The Effect of Blindness on Biological Rhythms and the Consequences of Circadian Rhythm Disorder

open access: yesTürk Oftalmoloji Dergisi, 2023
Various physiological systems and behaviors such as the sleep-wake cycle, vigilance, body temperature, and the secretion of certain hormones are governed by a 24-hour cycle called the circadian system.

Relations between depressed mood and vocal parameters before, during and after sleep deprivation: a circadian rhythm study [PDF]

open access: yes, 1990
The mechanism underlying improvement after total sleep deprivation (TSD) was studied in 14 major depressed patients. The suggestions that (1) circadian processes and/or (2) dimensions of arousal may play a role in the response to TSD were investigated ...
