Age-related reorganization of locus coeruleus-cortical functional connectivity gradients

This study examines age-related changes in locus coeruleus-cortical functional connectivity gradients using MRI and PET data, finding reduced functional differentiation in older adults during negative emotional stimuli.

Global brain maintenance predicts well-preserved cognitive function: A pooled analysis of three longitudinal population-based Swedish cohorts

This study shows that maintaining brain integrity through aging is linked to better cognitive function and slower decline, with lifestyle factors like lower cardiovascular risk and no diabetes playing a role.

Functional connectivity profile of the amygdala subfields associates with emotional well-being in aging

The paper examines age-related changes in amygdala subfield functional connectivity and its association with emotional resilience using fMRI data from younger and older adults.

Resilience-driven neural synchrony during naturalistic movie watching

This study examines resilience-driven neural synchrony during movie watching, finding stronger synchrony in negative vs. neutral movies and linking it to individual resilience and intolerance of uncertainty.

Multiple neural pathways to successful visual short-term memory across the adult lifespan

The paper identifies subgroups with distinct brain activation patterns during a visual short-term memory task across the adult lifespan, showing differences in brain activity-performance associations and white matter integrity.

Frontoparietal functional dedifferentiation during naturalistic movie watching among older adults at risk of emotional vulnerability

This study examines functional dedifferentiation in the frontoparietal network during naturalistic movie watching in older adults, linking it to depressive symptoms and emotion regulation difficulties.

Compression of functional gradients from rest to naturalistic processing: Moderation effect of age

This study compares brain organization during rest and naturalistic processing, finding greater functional gradient compression in older adults linked to worse cognitive performance.

Two long-axis dimensions of hippocampal cortical integration support memory function across the adult lifespan

The paper shows two hippocampal integration dimensions persist across adulthood, relate to memory and dopamine distribution, and decline with age.

Dedifferentiation of caudate functional organization is linked to reduced D1 dopamine receptor availability and poorer memory function in aging

The paper investigates how reduced dopamine D1 receptor availability in aging is linked to decreased functional specificity in cortico-striatal circuits and poorer memory performance.

Brain-Cognitive Gaps in relation to Dopamine and Health-related Factors: Insights from AI-Driven Functional Connectome Predictions

The paper uses deep learning to predict cognitive performance from functional connectomes during different brain states and identifies the brain-cognition gap as a dopamine-related marker of cognitive vulnerability.

Evaluating the position of the uncal apex as a predictor of episodic memory across the adult lifespan

This study examines how the position of the uncal apex relates to episodic memory across adulthood, finding that its anterior shift with age correlates with poorer memory performance.

Dopamine D1-receptor Organization Contributes to Functional Brain Architecture

The paper shows that dopamine D1 receptor organization in humans aligns with a unimodal-to-transmodal functional gradient and influences network differentiation and connectivity.

The iron-dopamine D1 coupling modulates neural signatures of working memory across adult lifespan

The paper investigates the relationship between brain iron levels and dopamine D1 receptors across the adult lifespan, finding that elevated iron and reduced D1DR in older adults correlate with impaired working memory.

Hub architecture of the human structural connectome: Links to aging and processing speed

The paper examines how aging affects structural brain hubs using fiber bundle capacity, finding that hub connections are more vulnerable to age-related declines in processing speed.

Bi-phasic patterns of age-related differences in dopamine D1 receptors across the adult lifespan

The paper identifies a bi-phasic pattern of age-related dopamine D1 receptor decline, with distinct functional consequences before and after 40 years of age.

Dynamic regulation of neural variability during working memory reflects dopamine, functional integration, and decision-making

This study examines how neural variability during working memory is regulated by dopamine, functional integration, and decision-making using PET and fMRI data.
