This study compares tissue-specific MRI smoothing methods and their impact on statistical inference, finding that different approaches affect sensitivity and model fit in distinct brain regions.

COFITAGE provides a longitudinal neuroimaging dataset for studying brain aging, integrating MRI, PET, genetics, and cognitive assessments across 50-70 year olds.

This study examines how light affects hypothalamic activity in adolescents and young adults across different times of day, finding stable regional responses with developmental differences in magnitude.

This study evaluates how protocol and hardware differences affect pooling quantitative MRI data across sites in healthy aging studies, finding both benefits and drawbacks for analysis outcomes.

The paper examines how polygenic risk for Parkinson's disease relates to REM sleep metrics in young and late-midlife individuals, finding age-dependent associations.

This study investigates how seasonal changes, mood, and light exposure affect regional activity in the human amygdala using fMRI.

The paper examines diurnal changes in brain network dynamics and their association with cognitive aging and Alzheimer's disease markers.

This study examines how blue light affects cortical excitability in adolescents and young adults, finding age-related differences in response.

This study examines the relationship between effective connectivity between the locus coeruleus and hypothalamus subregions and sleep electrophysiology in young and older adults.

This study identifies group-specific brain activity patterns related to fatigue in early Multiple Sclerosis patients and healthy controls using fMRI.

This study examines how napping affects functional brain responses in older adults during a working memory task, finding differences in brain activity and performance between nappers and non-nappers.

This study shows that light affects thalamo-cortical connectivity during a cognitive task, with differences based on time of day and age group.

The paper investigates the relationship between locus coeruleus (LC) activity during wakefulness and REM sleep quality in humans, finding task-dependent associations.

This study investigates how varying light levels affect different regions of the human hypothalamus during cognitive tasks, finding distinct activity patterns linked to task performance.

This study shows blue-enriched light enhances thalamo-cortical connectivity during an auditory attention task, supporting its role in modulating cognitive activity.

The paper investigates the association between brainstem myelin content and sleep parameters in healthy young men, finding significant links between myelin integrity and sleep quality metrics.

This study finds that higher locus coeruleus activity during wakefulness in older adults is linked to worse sleep quality and reduced theta band power during REM sleep.

The paper investigates the relationship between structural and functional characteristics of the locus coeruleus in young and late middle-aged individuals using MRI and finds no association between LC contrast and functional response.

The paper examines the link between spindle-slow wave coupling during sleep and early amyloid-β burden, finding it associated with memory decline in midlife individuals.

The paper introduces PET-BIDS, an extension of the BIDS standard for PET data, and provides curated datasets and tools for its use.

The paper introduces a data-driven method to restore statistical validity in MRI group analyses by assigning image weights based on quality indices, improving performance across brain regions despite motion effects.

The paper compares visual and automatic sleep scoring methods to assess their reliability and variability in large datasets, finding that automatic scoring can be a reliable reference when reproducible.

The paper shows that preserved cortical excitability during wakefulness is linked to better cognitive performance in older adults, independent of brain structural changes.
