This paper investigates how age-related changes in frontoparietal brain activity mediate declines in fluid intelligence and identifies physical activity variety as a potential modifiable factor.

This study investigates how dopamine levels in Parkinson’s disease patients affect sensory attenuation during voluntary movements, finding a negative correlation with motor severity and a positive correlation with dopamine dose.

This study examines the associations between cardiovascular risk factors and white matter structure in aging, finding that systolic blood pressure, diastolic blood pressure, and heart rate independently impact white matter health.

The paper shows that physical activity preserves frontal white matter integrity and reduces age-related slowing in a population-based sample.

This study investigates age-related differences in sleep quality and their associations with health outcomes in a UK cohort of 2406 adults, finding stronger links with mental health and u-shaped associations between sleep duration and mental health.
