The paper examines age-related changes in white matter microstructural properties within the cortico-striato-pallido-thalamic loop using NODDI, finding age-sensitive spatial gradients and an inverted-U association with age.

The paper investigates how age-related changes in brain structure and function interact to affect cognitive performance in older adults.

This study examines age-related changes in cerebello-thalamo-cortical white matter and their association with executive function performance across adulthood.

The paper develops a harmonized segmentation protocol for hippocampal subfields in MRI, improving cross-study comparisons and understanding of subfield structure and function.

The paper presents a harmonized segmentation protocol for the hippocampal tail in high-resolution MRI, improving cross-study comparability through standardized definitions and consensus-based guidelines.

The paper examines age-related changes in gray and white matter structural properties using a longitudinal design and histology-informed parcellation, finding coupled aging gradients in specific brain regions.

The paper examines age-related changes in corpus callosum microstructure and how pulse pressure modifies these changes across different subregions.

This study shows that vascular factors like blood pressure and white matter hyperintensity burden mediate age-related declines in executive function via changes in white matter microstructure.

This study investigates how aging affects functional connectivity during working memory tasks and finds that task-related connectivity remains robust with age, while negative connectivity between brain regions correlates with better performance in older adults.

The paper examines age-related changes in optic radiation white matter and their association with visual and verbal executive functions, finding that degraded white matter correlates with poorer visual executive function in older adults.

The paper shows that reduced white matter anisotropy in the inferior longitudinal fasciculus predicts functional dedifferentiation in ventral visual cortex with aging.

The paper examines how striatal iron content affects BOLD modulation during working memory tasks and finds an age-dependent interaction with reduced modulation and poorer executive function.

This study examines age-related changes in cortical morphometry and white matter microstructure using partial least squares correlation, finding a coupled relationship between frontal and parietal grey matter and underlying white matter.

This study shows that aging reduces white matter integrity and BOLD modulation, which together impair cognitive performance and executive function.
