This study shows light modulates locus coeruleus (LC) activity in an emotion-dependent manner, with higher illuminance dampening responses to negative stimuli and enhancing neutral ones.

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 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 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 examines how different light levels affect task-evoked pupil responses during cognitive tasks, finding that higher light levels increase pupil dilation in response to auditory stimuli.

The paper investigates how repeated short light exposures affect sustained pupil responses during different cognitive tasks, finding that higher melanopic irradiance increases pupil responses and that task context influences variability.

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

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.
