Structure–Function Correlates of Cognitive Decline in Aging

TL;DR: In this paper, structural and diffusion tensor imaging (DTI) revealed a heterogeneous set of differences associated with cognitive decline in aging, and suggested that increased activation is either caused by structural disruption or is a compensatory response to such disruption.
Journal ArticleDOI

Age Differences in Deactivation: A Link to Cognitive Control?

TL;DR: Demand-related changes in deactivation magnitude correlated with performance changes, suggesting that individual and group differences in de activation have functional significance.
Journal ArticleDOI

Longitudinal evidence for diminished frontal cortex function in aging

TL;DR: These findings dispute inferences of true age changes on the basis of age differences, hence challenging some contemporary models of neurocognitive aging, and demonstrate age-related decline in frontal brain volume as well as functional response.
Journal ArticleDOI

Common prefrontal activations during working memory, episodic memory, and semantic memory

TL;DR: Compared the activation patterns associated with tests of working memory, semantic memory and episodic memory, the results converged on a general involvement of four regions across memory tests, providing evidence that some PFC regions are engaged during many different memory tests.
