The paper examines brain activity and cognitive performance in older adults during a problem-solving task, finding increased cuneal cortex activity with age and performance, suggesting functional compensation for fluid intelligence.

The paper investigates attentional biases to angry faces in individuals in remission from depression using functional MRI and drift diffusion modeling, finding persistent biases linked to brain activity in emotional regulation regions.

This study shows cortical thickness is more linked to aging, while surface area is more linked to cognitive abilities, using brain imaging data from healthy adults.

The paper investigates whether age-related hemispheric asymmetry reduction in motor cortex reflects compensation, finding no evidence for a compensatory mechanism.

The paper investigates age-related changes in the ipsilateral M1 BOLD response using dynamic causal modelling on fMRI data from the Cam-CAN dataset, finding increased positive connectivity from SMA and PMd with age.

This paper decodes grasp typicality from hand-selective brain regions during real tool grasping, showing these regions encode how to grasp 3D tools even without tool use or object knowledge.

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.
