This study examines how cortical thickness and surface area contribute to cognitive ageing using longitudinal data from multiple cohorts, finding thickness declines more steeply and is more strongly linked to cognitive change.

This study identifies how different environmental factors affect cortical architecture in twins, showing persistent early life effects and training-induced changes in adulthood.

The paper establishes a normative reference for large-scale human brain dynamics using resting-state fMRI data from over 10,000 individuals, revealing systematic reorganization across development and ageing and disorder-specific deviations in mental health conditions.

The paper identifies a subset of older adults with stable memory performance over time, linking this stability to brain structure and showing it is often transient rather than consistent.

The paper examines age-related changes in functional connectivity between the dLPFC and DMN during memory tasks and links it to cognitive control decline in aging.

This study examines how brain volume differences in adults are stable from young adulthood or change with age, using MRI data from 8,311 individuals.

The paper shows cortical thickness changes occur years before high amyloid levels in Alzheimer's disease, challenging the view that amyloid is the first imaging marker.

This study shows brain age metrics from MRI do not reliably predict future brain changes but highlight modality-specific differences as potential cross-sectional markers.

This study investigates the relationship between brain atrophy and memory decline in aging using longitudinal data, finding a nonlinear association that intensifies with age and is influenced by APOE ε4 carriership.

The paper examines how brain network segregation relates to episodic memory performance across age, finding age-invariant associations between functional connectivity and memory.

This study assesses the reliability of structural brain change in cognitively healthy adults over time, finding that longer follow-up periods significantly improve reliability compared to increasing observation frequency.

The paper identifies subtypes of brain structural changes in aging and links them to cognitive decline and Alzheimer's disease biomarkers using MRI data.

This study evaluates the stability of brain structure metrics over one year and identifies factors affecting their reliability.

The study investigates whether superior memory in older adults (SuperAgers) is linked to unique brain features, finding stable correlates of memory function across age without evidence of aging-specific differences.

The paper shows that higher genetic risk for Alzheimer's disease is linked to faster brain volume loss and memory decline in healthy adults.

This study identifies stable and task-specific hippocampal-cortical connectivity patterns during memory encoding and retrieval using fMRI data from two large-scale studies.

The paper investigates the effects of short sleep on brain structure and cognitive function, finding that short sleepers without daytime tiredness have larger brain volumes but slightly lower cognitive scores.

The paper analyzes cortical asymmetry across age and datasets, finding stable areal asymmetry and developmental changes in thickness asymmetry, with genetic and phenotypic associations.

The paper estimates brain age gap (BAG) using neural networks and identifies eight genomic regions associated with BAG, finding causal relationships with Alzheimer's and bipolar disorder but not Parkinson's, depression, or schizophrenia.

This study shows that birth weight consistently correlates with cortical surface area and volume across the lifespan, suggesting prenatal growth influences brain structure through brain reserve rather than maintenance.

The paper investigates hippocampal-neocortical coupling after memory encoding and finds widespread upregulation of functional connectivity during post-encoding rest, suggesting broader reactivation beyond perceptual aspects.

The paper investigates how general cognitive ability relates to cortical brain volume changes over time, finding associations with both brain reserve and maintenance mechanisms.

The paper examines age-related variations in cortical thickness across different life stages using gene expression data from a large neuroimaging dataset.

This study examines the relationship between sleep duration and brain structure using MRI data, finding that 6.8 hours of sleep is associated with the most favorable brain outcomes, with genetic analyses suggesting homeostatic regulation of sleep duration.

The paper examines age-related changes in whole-brain connectivity during memory encoding and links these changes to cognitive and brain structural decline.

This study finds that adult brain age is more influenced by early life factors like birth weight and polygenic scores than by longitudinal brain decline.

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.

The paper identifies asymmetric thinning of the cerebral cortex across aging and Alzheimer's Disease, showing that the initially thicker hemisphere thins faster, with this pattern replicated across multiple cohorts.

The paper links cortical thinning across the lifespan to gene expression profiles of specific cell types using gene expression data and MRI datasets.

This study investigates whether the functional foundations of episodic memory encoding remain consistent across the lifespan, finding continuity rather than late-life specificity.
