Exercise and Alzheimer's disease biomarkers in cognitively normal older adults.

OBJECTIVE In addition to the increasingly recognized role of physical exercise in maintaining cognition, exercise may influence Alzheimer's disease (AD) pathology, as transgenic mouse studies show lowered levels of AD pathology in exercise groups. The objective of this study was to elucidate the association between exercise and AD pathology in humans using Pittsburgh compound-B (PIB), amyloid-b...

Neural correlates of self-focused attention in social anxiety.

Socially anxious individuals tend to shift their attention away from external socially threatening cues and instead become highly self-focused. Such heightened self-focused attention has been suggested to be involved in the development and maintenance of social anxiety disorder. This study used functional magnetic resonance imaging to investigate the neural correlates of self-focused attention ...

Neural correlates of focused attention during a brief mindfulness induction.

Mindfulness meditation-the practice of attending to present moment experience and allowing emotions and thoughts to pass without judgment-has shown to be beneficial in clinical populations across diverse outcomes. However, the basic neural mechanisms by which mindfulness operates and relates to everyday outcomes in novices remain unexplored. Focused attention is a common mindfulness induction w...

Neural correlates of auditory recognition under full and divided attention in younger and older adults.

We examined how aging affects the pattern of brain activity mediating retrieval under dual-task conditions. We used functional magnetic resonance imaging (fMRI) to measure brain activity in younger and older adults while they were engaged in an auditory verbal recognition test under either full or divided attention (FA or DA). During recognition under FA, older adults had more activity in bilat...

Neural correlates of executive attention in adults born very preterm

Very preterm birth is associated with an increased prevalence of attention problems and may especially impair executive attention, i.e., top-down control of attentional selection in situations where distracting information interferes with the processing of task-relevant stimuli. While there are initial findings linking structural brain alterations in preterm-born individuals with attention prob...
