In this dynamic causal modeling (DCM) study, we evaluated the effect of age on the effective
connectivity of a cerebral network involved in lexical production. Younger and older adults …

Although older adults exhibit normal accuracy in performing word retrieval and generation
(lexical production; eg, object naming), they are generally slower in responding than …

As people age, there is a natural decline in cognitive functioning and brain structure.
However, the relationship between brain function and cognition in older adults is neither …

In the absence of any neuropsychiatric condition, older adults may show declining
performance in several cognitive processes and among them, in retrieving and producing …

Human behavioral data indicate that older adults are slower to perform lexical decisions
(LDs) than young adults but show similar reaction time gains when these decisions are …

Normal aging is accompanied by changes in both structural and functional cerebral
organization. Although verbal knowledge seems to be relatively stable across the lifespan …

This study aimed to explore the effects of transcranial direct current stimulation (tDCS) on
physiologically aging adults performing a naming task. tDCS is a method that modulates …

Brain function is thought to become less specialized with age. However, this view is largely
based on findings of increased activation during tasks that fail to separate task-related …

Healthy aging is associated with a heterogeneous decline across cognitive functions,
typically observed between language comprehension and language production (LP) …

Aging is often associated with cognitive and neural decline, and such changes can have
significant social, financial, and societal costs. Moreover, older adults represent the largest …
