The Sleeping Brain, Seen Whole Sleep transforms the brain. Slow waves sweep across the cortex, sleep spindles burst in the thalamus, and theta rhythms mark the transition into deeper rest. But for decades, the map of these electrical sleep oscillations has been incomplete. Most human neuroimaging studies have focused on the cerebral cortex, the wrinkled […]
Agreement between automated and manual scoring of level 3 home sleep apnea devices A single-center retrospective study finds that automated scoring of home sleep apnea tests systematically underestimates disease severity, misclassifying nearly half of moderate cases. Lead Home sleep apnea testing (HSAT) has become a cornerstone of obstructive sleep apnea (OSA) diagnosis, offering patients a […]
Lead A non-invasive MRI technique that measures neuromelanin in the brainstem may help identify which patients with idiopathic REM sleep behavior disorder (iRBD) are at risk for dopamine system damage, according to a study published July 6 in Brain Imaging and Behavior. The technique could serve as a radiation-free triage tool, potentially reducing the need […]

In children and adolescents with narcolepsy type 1 (NT1), the severity of excessive daytime sleepiness is driven largely by how poorly they sleep at night, not just by the narcolepsy itself, according to a cross-sectional study of 114 patients published in the Zhonghua Yi Xue Za Zhi (Chinese Medical Journal). The finding challenges a common […]
Three months of balance training significantly improved subjective sleep quality in adults aged 64 to 81, driven by enhanced GABAergic inhibition in the sensorimotor cortex, according to a study published July 5 in The Journal of Physiology. The finding offers a potential non-pharmacological alternative for the nearly half of all adults over 60 who experience […]
Twenty-one days of constant light suppresses liver protein production by roughly 16% and decimates key circadian clock proteins, but the hormone melatonin fully reverses the damage in both sexes, according to a study published July 4 in Biology of Sex Differences. The findings carry direct implications for shift workers, frequent long-haul travelers, and anyone living […]
A retrospective analysis of 12,036 obstructive sleep apnea patients at a single sleep center finds that two-thirds, 66.3%, have positional OSA (POSA), defined as a supine apnea-hypopnea index at least double the non-supine AHI. Published July 4 in Sleep & Breathing, the study provides one of the largest characterizations of POSA’s clinical and polysomnographic signature […]
New brain imaging evidence shows that insomnia complicated by anxiety selectively damages the peripheral connections of the brain’s structural network while sparing its central “rich club” hub architecture. The study, published June 30 in Psychiatry Research: Neuroimaging, provides the clearest picture yet of how white matter integrity breaks down in patients suffering from both conditions […]
