Sleep dysfunction mediates the relationship between hemodynamic response height of the secondary somatosensory cortex and fear-somatic symptom severity bidirectionally in young adults

This study of 735 young adults reveals that sleep dysfunction bidirectionally mediates the relationship between reduced hemodynamic response height in the secondary somatosensory cortex and increased fear-somatic symptom severity.

Aberrant anterior insular functional connectivity patterns and intestinal microbiota differences in mild traumatic brain injury patients accompanied by cognitive impairment

This study reveals that mild traumatic brain injury patients with cognitive impairment exhibit distinct gut microbiota alterations and disrupted anterior insular functional connectivity, suggesting a potential gut-brain axis mechanism involving specific bacterial genera that may contribute to mood disorders and cognitive deficits.

Using wearable EEG to examine age trends in sleep macro- and micro-architecture across adolescence

This study demonstrates that the Dreem3 wearable EEG headband successfully replicates established age-related trends in sleep macro- and micro-architecture across adolescence, validating it as an accessible alternative to traditional laboratory polysomnography for characterizing sleep physiology development.

Mild and Reversible Proprioception Perturbation Suggests Causal Biomechanics for Memory-Dependent Spatial Behavior in Mice

This study demonstrates that acute, reversible optogenetic perturbation of proprioceptive inputs in mice impairs memory-dependent spatial navigation, providing the first causal evidence for the peripheral nervous system's role in path-integration biomechanics.

Exploration of key genes associated with pyruvate metabolism in nonalcoholic fatty liver disease based on single-cell and bulk RNA-seq data

This study integrates bulk and single-cell RNA sequencing with experimental validation to identify ACOT12 and SLC16A1 as pivotal pyruvate metabolism-related genes in nonalcoholic fatty liver disease, elucidating their roles in immune infiltration and disease progression while proposing potential therapeutic small molecules.

Effect of sports experience on changes associated with maintaining neck flexion in distribution of pro-saccade reaction time under gap task

This study demonstrates that sports experience, specifically in basketball and table tennis, facilitates earlier pro-saccade reaction times under a gap task when maintaining a neck flexion position, with the specific distributional changes varying by sport type compared to non-athletic controls.

RGS10 controls the metabolic and neuroinflammatory benefits of NLRP3 suppression in diet-induced obesity in male mice.

This study identifies RGS10 as a critical, sex-dependent upstream regulator of the NLRP3 inflammasome in male mice, demonstrating that its loss abolishes the metabolic and neuroinflammatory benefits of NLRP3 suppression in diet-induced obesity and suggesting that age-related RGS10 decline may limit the efficacy of NLRP3-targeted therapies.
