Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

Advanced Science, Volume 13, Issue 45, 13 August 2026.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Work‐Influenced Circadian Disruption Connected to Disease Risk but Not Microbiomes in a Cohort of Philadelphia Nurses

American Journal of Human Biology, Volume 38, Issue 8, August 2026.
ABSTRACT Objectives Circadian rhythms influence activity cycles in humans, and circadian rhythm disruption (CRD) can negatively impact cardiometabolic disease risk and microbiome composition. This study documented CRD in a sample of nurses in Philadelphia, examining connections between CRD, disease risk, and work environment factors, proposing the ...

Bipolarity as an Independent Correlate of Clinical Profiles in Insomnia: A Factorial Analysis Across Multiple Clinical Domains

Brain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Background This study investigated the independent and interactive effects of bipolarity (subthreshold bipolar spectrum features) on multidimensional clinical profiles in individuals with insomnia, using data from a comprehensive deep phenotyping study.

Resting‐State EEG Functional Connectivity in Young Adults With Clinically Diagnosed Generalized Anxiety Disorder and Self‐Reported Habitual Short Sleep: An Alpha‐Band Network Analysis

Brain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Background Generalized anxiety disorder (GAD) is commonly accompanied by sleep disturbance in young adults. Whether clinically diagnosed GAD with self‐reported habitual short sleep (HSS) is associated with altered resting‐state large‐scale functional connectivity remains unclear. We examined EEG functional connectivity in young adults with GAD

Altered Evening Aperiodic Activity and Microstate Dynamics in Insomnia Disorder: An OPM MEG Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Using wearable OPM‐MEG, this study characterized evening and morning resting state neurophysiology in insomnia disorder. A flatter evening aperiodic spectral exponent suggested relatively elevated cortical excitability, alongside altered microstate dynamics involving putative limbic and sensorimotor network states.
