Introduction: Working memory (WM) and its blood-oxygen-level-dependent-related parametric modulation under load decrease with age. Functional connectivity (FC) generally increases with WM load; however, how aging impacts connectivity and whether this is load-dependent, region-dependent, or associated with cognitive performance is unclear. Methods:...

Moment-to-moment fluctuations in brain signal assessed by functional magnetic resonance imaging blood oxygenation level dependent (BOLD) variability is increasingly thought to represent important "signal" rather than measurement-related "noise." Efforts to characterize BOLD variability in healthy aging have yielded mixed outcomes, demonstrating bot...

Working memory (WM) and its BOLD-related parametric modulation under load decrease with age. Functional connectivity (FC) generally increases with WM load; however, how aging impacts connectivity and whether this is load-dependent, region-dependent, or associated with cognitive performance is unclear. This study examines these questions in 170 heal...

Performing relational comparisons is considered among the most intelligent cognitive capacities. Animal studies have demonstrated that chimpanzees and crows are capable of relational reasoning with second-order relationships (e.g., analogies); however, it has been hypothesized that only humans are capable of reasoning with third-order relationships...

Metabolic syndrome (MetS) is a cluster of cardiovascular and metabolic abnormalities that together may increase the risk of developing cognitive decline and dementia; however, the neural substrate is incompletely understood. We investigated cortical thickness in the medial temporal lobe (MTL), hippocampal volume, as well as relationships among meta...
