In recent years, several theories have been proposed in attempts to identify the neural
mechanisms underlying successful cognitive aging. Old subjects show increased neural …

Healthy aging (HA) is associated with certain declines in cognitive functions, even in
individuals that are free of any process of degenerative illness. Functional magnetic …

Abstract Characterization of normal age-related changes in resting state brain networks
associated with working memory performance is a major prerequisite for studying …

Normal aging is associated with cognitive decline. Functions such as attention, information
processing, and working memory are compromised. It has been hypothesized that not only …

Functional connectivity–the co-activation of brain regions–forms the basis of the brain's
functional architecture. Often measured during resting-state (ie, in a task-free setting) …

Convergent evidence from task-based functional magnetic resonance imaging (fMRI)
studies suggests a posterior-to-anterior shift as an adaptive compensatory scaffolding …

Healthy aging is associated with structural and functional changes in the brain even in
individuals who are free of neurodegenerative diseases. Using resting state functional …

Normal aging is associated with cognitive decline and underlying brain dysfunction.
Previous studies concentrated less on brain network changes at a systems level. Our goal …

Correlations in activity across disparate brain regions during rest reveal functional networks
in the brain. Although previous studies largely agree that there is an age-related decline in …

Cognition occurs by virtue of neural processes, and likewise, the aging of cognition is rooted
in the effects of age on neural structures and functions. The methods of cognitive …
