How to Catch a Blank Mind? Brain Similarities and Differences between Self- and Probe-Caught Mind Blanking

The paper compares brain activity during self-caught and probe-caught mind blanking events using fMRI, finding behavioral convergence but neural divergence in the dorsal anterior cingulate cortex.

Cognitive Fitness in Ageing (COFITAGE): A Multimodal and Longitudinal Neuroimaging Dataset

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

In vivo modulation of locus coeruleus activity by light

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.

Regional Hypothalamic Responses to Light Vary Across Developmental Stages but Remain Stable with Time of Day

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.

Pooling quantitative MRI data: A multi-protocol study of healthy subcortical ageing

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.

Age-related differences in the association between REM sleep and the polygenic risk for Parkinson's disease

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.

Regional activity within the human amygdala varies with season, mood and illuminance

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

Diurnal dynamics of multilayer brain networks predict cognitive trajectories in aging

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

Cortical Excitability is Affected by Light Exposure - Distinct Effects in Adolescents and Young Adults

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

Sleep arousals are associated with the polygenic risk for developing Alzheimer's disease and with cognitive decline in healthy late middle-aged individuals

This study links specific sleep arousal subtypes to polygenic risk for Alzheimer's disease and cognitive decline in late middle-aged individuals.

The crosstalk between the anterior hypothalamus and the locus coeruleus during wakefulness is associated with low frequency oscillations power during sleep

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

The specificity of fatigue cerebral substrates in early Multiple Sclerosis - An fMRI study

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

Napping alters Functional Brain Responses in the Aged

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.

Light Impact on Thalamo-Cortical Connectivity During a Cognitive Task Depends on Time of Day and is Different in Teenagers

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

REM sleep quality is associated with balanced tonic activity of the locus coeruleus during wakefulness

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

Regional response to light illuminance across the human hypothalamus

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.

Daily dynamics of resting-state EEG theta and gamma fluctuations are associated with cognitive performance in healthy aging

The paper examines daily fluctuations of theta and gamma EEG rhythms in healthy aging and links them to cognitive performance and biomarkers of neurodegeneration.

7 Tesla MRS estimates of GABA concentration relate to physiological measures of tonic inhibition in the human motor cortex

The paper uses 7 Tesla MRS and TMS-hdEEG to show that MRS-GABA correlates with physiological measures of tonic inhibition in the human motor cortex.

In vivo marker of brainstem myelin is associated to quantitative sleep parameters in healthy young men

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.

In vivo Locus Coeruleus activity while awake is associated with REM sleep quality in healthy older individuals

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.

Timely sleep coupling: spindle-slow wave synchrony is linked to early amyloid-β burden and predicts memory decline

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.

Preserved wake-dependent cortical excitability dynamics predict cognitive fitness beyond age-related brain alterations

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