The retinal ipRGC-preoptic circuit mediates the acute effect of light on sleep

open access: yesNature Communications, 2021
The preoptic area (POA) is critical for sleep regulation but its role in acute, non-circadian, light effects on sleep are unclear. The authors show that intrinsically photosensitive retinal ganglion cells provide substantial input into the POA and ...

Accuracy of Three Commercial Wearable Devices for Sleep Tracking in Healthy Adults

open access: yesSensors
Sleep tracking by consumers is becoming increasingly prevalent; yet, few studies have evaluated the accuracy of such devices. We sought to evaluate the accuracy of three devices (Oura Ring Gen3, Fitbit Sense 2, and Apple Watch Series 8) compared to the ...

NREM delta power and AD-relevant tauopathy are associated with shared cortical gene networks

open access: yesScientific Reports, 2021
Reduced NREM sleep in humans is associated with AD neuropathology. Recent work has demonstrated a reduction in NREM sleep in preclinical AD, pointing to its potential utility as an early marker of dementia.

A miR-219-5p-bmal1b negative feedback loop contributes to circadian regulation in zebrafish

open access: yesCommunications Biology
MicroRNAs post-transcriptionally regulate gene expression and contribute to numerous life processes, including circadian rhythms. However, whether miRNAs contribute to zebrafish circadian regulation has not yet been investigated.

CCorGsDB: a database for clock correlated genes in the mouse and human central nervous systems

open access: yesnpj Biological Timing and Sleep
We developed CCorGsDB, a web-based resource integrating mouse and human CNS co-expression networks filtered by circadian biomarkers. We validated the networks using time-series data from sixteen mouse regions and identified a conserved set of 251 ...

COMPASS: Continuous Open Mouse Phenotyping of Activity and Sleep Status [version 2; referees: 3 approved, 1 approved with reservations]

open access: yesWellcome Open Research, 2017
Background: Disruption of rhythms in activity and rest occur in many diseases, and provide an important indicator of healthy physiology and behaviour. However, outside the field of sleep and circadian rhythm research, these rhythmic processes are rarely ...

Physiology of Circadian Entrainment [PDF]

open access: yesPhysiological Reviews, 2010
Mammalian circadian rhythms are controlled by endogenous biological oscillators, including a master clock located in the hypothalamic suprachiasmatic nuclei (SCN). Since the period of this oscillation is of ∼24 h, to keep synchrony with the environment, circadian rhythms need to be entrained daily by means of Zeitgeber (“time giver”) signals, such as ...

Sake yeast induces the sleep-promoting effects under the stress-induced acute insomnia in mice

open access: yesScientific Reports, 2021
Sleep deprivation induces adverse effects on the health, productivity, and performance. The individuals who could not get enough sleep temporarily experience the symptoms of an induced acute insomnia. This study investigated the efficacy of sake yeast in

Objective Assessment of Daytime Napping and Incident Heart Failure in 1140 Community‐Dwelling Older Adults: A Prospective, Observational Cohort Study

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Disrupted nighttime sleep has been associated with heart failure (HF). However, the relationship between daytime napping, an important aspect of sleep behavior commonly seen in older adults, and HF remains unclear. We sought to investigate the
