Abstract
Circadian rhythms are inherent to living organisms from single cells to humans and operate on a genetically determined cycle of approximately 24 hours. These endogenous rhythms are aligned with the external light/dark cycle of the Earth's rotation and offer the advantage of anticipating environmental changes. Circadian rhythms act directly on human cognition and indirectly through their fundamental influence on sleep/wake cycles. The strength of the circadian regulation of performance depends on the accumulated sleep debt and the cognitive domain, and it has been suggested to involve the activation of ascending arousal systems and their interaction with attention and other cognitive processes. In addition, attention-related cortical responses show extensive circadian rhythms, the phases of which vary across brain regions. This review discusses the impact of the circadian system on sleep/wake regulation and cognitive performance. It further addresses the health implications of circadian disruption, particularly in relation to mental and neurological disorders.
期刊介绍：
The Annual Review of Psychology, a publication that has been available since 1950, provides comprehensive coverage of the latest advancements in psychological research. It encompasses a wide range of topics, including the biological underpinnings of human behavior, the intricacies of our senses and perception, the functioning of the mind, animal behavior and learning, human development, psychopathology, clinical and counseling psychology, social psychology, personality, environmental psychology, community psychology, and much more. In a recent development, the current volume of this esteemed journal has transitioned from a subscription-based model to an open access format as part of the Annual Reviews' Subscribe to Open initiative. As a result, all articles published in this volume are now freely accessible to the public under a Creative Commons Attribution (CC BY) license.
