Rapid expansion and renormalization of parietal gray matter volume following associative learning

This study shows that parietal gray matter volume expands and renormalizes within hours after associative learning, with changes linked to memory retention and sleep.

Learning sculpts microstructure in real time: evidence from dense temporal sampling of diffusion MRI

This study uses dense diffusion MRI sampling to show that learning induces microstructural changes in the brain, specifically in the left middle occipital/temporal gyrus, during and after a memory task.

Incorporation of complex narratives into dreaming

This study investigates how daytime narratives are incorporated into dreams and their relation to memory consolidation, finding that dream content reflects studied material and better recall correlates with stronger incorporation.

Pre-sleep experiences shape neural activity and dream content in the sleeping brain

This study shows that pre-sleep audiobooks influence neural activity and dream content during REM sleep, with beta power and neural reinstatement linked to memory performance.

Random auditory stimulation disturbs traveling slow waves and declarative memory

This study investigates how random auditory stimulation during sleep affects slow-wave dynamics and declarative memory, finding reduced slow-wave sleep and impaired memory recall.

Spindle-dependent memory consolidation in healthy adults: A meta-analysis

This paper conducts a meta-analysis of 53 studies to examine the relationship between sleep spindles and memory performance, finding a small to moderate effect with stronger associations for procedural memory.

Alterations in rhythmic and non-rhythmic resting-state EEG activity and their link to cognition in older age

The paper investigates age-related changes in EEG biomarkers and their association with cognitive performance in older adults.

Rapid volumetric brain changes after acute psychosocial stress

This study examines rapid volumetric brain changes after acute psychosocial stress using MRI and finds significant group-by-time interactions in grey matter volume and associations with stress measures.

Relationship between Regional White Matter Hyperintensities and Alpha Oscillations in Older Adults

The paper investigates the relationship between white matter hyperintensities and alpha oscillations in older adults, finding that WMHs are associated with elevated alpha power but not with peak frequency or long-range temporal correlations.

Hemispheric asymmetries in resting-state EEG and fMRI are related to approach and avoidance behaviour, but not to eating behaviour or BMI

The paper examines hemispheric asymmetries in EEG and fMRI related to approach and avoidance behavior, finding no significant links to eating behavior or BMI.

BOLD and EEG signal variability at rest differently relate to aging in the human brain

This study compares age-related changes in BOLD and EEG signal variability in healthy adults, finding distinct patterns and no significant associations between the measures.

A functional connectome phenotyping dataset including cognitive state and personality measures

The paper introduces a dataset linking brain functional architecture to cognitive states and personality traits through multimodal MRI and phenotypic assessments.

The age-dependent relationship between resting heart rate variability and functional brain connectivity

The paper examines how resting heart rate variability (HRV) relates to brain structure and function across different age groups, finding age-dependent changes in functional connectivity.

Association of Peripheral Blood Pressure with Grey Matter Volume in 19- to 40-Year-Old Adults

This study investigates the relationship between blood pressure and grey matter volume in young adults, finding that higher blood pressure correlates with reduced grey matter volume in specific brain regions.
