Cerebral blood flow in sleep: A systematic review and meta-analysis
Sleep plays an essential role in physiology, allowing the brain and body to restore itself. Despite its critical role, our understanding of the underlying processes in the sleeping human brain is still limited. Sleep comprises several distinct stages with varying depths and temporal compositions. Cerebral blood flow (CBF), which delivers essential nutrients and oxygen to the brain, varies across brain regions throughout these sleep stages, reflecting changes in neuronal function and regulation.
This systematic review and meta-analysis assesses global and regional CBF across sleep stages. We included, appraised, and summarized all 38 published sleep studies on CBF in healthy humans that were not or only slightly (<24 h) sleep deprived. Our main findings are that CBF varies with sleep stage and depth, being generally lowest in NREM sleep and highest in REM sleep. These changes appear to stem from sleep stage-specific regional brain activities that serve particular functions, such as alterations in consciousness and emotional processing.
期刊介绍:
Sleep Medicine Reviews offers global coverage of sleep disorders, exploring their origins, diagnosis, treatment, and implications for related conditions at both individual and public health levels.
Articles comprehensively review clinical information from peer-reviewed journals across various disciplines in sleep medicine, encompassing pulmonology, psychiatry, psychology, physiology, otolaryngology, pediatrics, geriatrics, cardiology, dentistry, nursing, neurology, and general medicine.
The journal features narrative reviews, systematic reviews, and editorials addressing areas of controversy, debate, and future research within the field.
