Structural Brain Indicators of Cognitive Performance in Middle and Late Adulthood: The Human Connectome Project in Aging/Aging Adult Brain Connectome Cohort

This study identifies structural brain differences associated with cognitive performance in middle and late adulthood using data from the Human Connectome Project.

Effects of diffusion MRI spatial resolution on human brain short-range association fiber reconstruction and structural connectivity estimation

This study evaluates how diffusion MRI spatial resolution affects short-range association fiber reconstruction and structural connectivity estimation, finding that higher resolution and specific tractography methods improve accuracy.

Functional MRI Signatures of Autonomic Physiology in Aging

This study examines age-related changes in fMRI signatures of autonomic physiology, finding slower respiratory responses and faster cardiac responses with aging, with a notable turning point after age 60.

The aging human brain exhibits reduced cerebrospinal fluid flow during sleep due to both neural and vascular factors

This study shows that aging reduces cerebrospinal fluid flow during sleep, linked to neural and vascular changes, and associated with gray matter atrophy.

The link between static and dynamic brain functional network connectivity and genetic risk of Alzheimer's disease

The paper examines the association between static and dynamic functional network connectivity and genetic risk of Alzheimer's disease using rs-fMRI and APOE data from cognitively normal individuals.

African Ancestry GWAS of Dementia in a Large Military Cohort Identifies Significant Risk Loci

This study performs a GWAS of dementia in African-ancestry individuals, identifying risk loci and highlighting differences in gene expression.

iSparse kmeans: a two-step clustering approach for big dynamic functional network connectivity data

The paper introduces iSparse kmeans, a two-step clustering method for large dFNC datasets, which is significantly faster than traditional kmeans while producing comparable results.

Disrupted dynamic functional network connectivity among cognitive control networks in the progression of Alzheimer's disease

This study examines dynamic functional connectivity in the cognitive control network across Alzheimer's disease stages, finding altered temporal connectivity patterns associated with symptom progression.

Conductance-Based Structural Brain Connectivity in Aging and Dementia

This paper quantifies structural brain connectivity using diffusion MRI in aging and dementia, finding age-related trends and regional effects that suggest potential for age prediction and studying structural connections.

The relationship between dynamic functional network connectivity and spatial orientation in healthy young adults

This study examines how dynamic functional network connectivity relates to spatial orientation in healthy young adults using resting-state fMRI and machine learning.

Spontaneous activity changes in large-scale cortical networks in older adults couple to distinct hemodynamic morphology

The paper develops a method to estimate transient states in neural networks using EEG and fMRI to show how neurovascular coupling differs across brain networks in older adults.
