This study introduces RIDA to reduce between-scan MRI intensity variations and improves longitudinal volume estimates, showing significant benefits for specific brain regions.

This paper introduces a method to normalize MRI intensity values across scans, improving consistency in volume measurements and spatial overlap between images.

This paper compares two whole-brain segmentation methods, ASEG and SAMSEG, in FreeSurfer, finding SAMSEG provides more reliable and sensitive measurements for detecting longitudinal changes and Alzheimer's disease-related atrophy.

This study finds that worse self-reported sleep relates to faster hippocampal microstructural decline in β-amyloid positive adults, independent of genetic risk.

The paper examines the relationship between self-reported sleep parameters and cortical thinning in aging, finding associations with specific brain regions but not with memory decline or amyloid-β accumulation.

The paper examines how self-reported sleep relates to hippocampal atrophy across adulthood using data from the Lifebrain consortium and UK Biobank, finding that worse sleep is linked to faster hippocampal volume loss over time.

The paper examines the relationship between sleep problems and amyloid deposition in cortical regions with high HOMER1 expression in older adults, finding a stronger link in younger participants and regions with high HOMER1 expression.

The paper examines developmental changes in extended delay memory and links them to structural hippocampal features in children and adolescents.

The paper examines lifespan changes in macro- and microstructure of anterior and posterior hippocampus and their relationship to memory across aging.

The paper identifies age-related waves of cortical myelination and demyelination using micro-structural MRI markers in humans across the lifespan.

This paper identifies continuous cortical regionalization from embryonic stages to old age using longitudinal data and gene expression analysis.
