Semantic cognition is central to understanding of language and the world and, unlike many
cognitive domains, is thought to show little age-related decline. We investigated age-related …

The acquisition, integration and storage of exogenous associated signals are termed as
associative learning and memory. The consequences and processes of associative thinking …

Elevated prefrontal cortex activity is often observed in healthy older adults despite declines
in their memory and other cognitive functions. According to one view, this activity reflects a …

The development of the brain, particularly the protracted maturation of the prefrontal cortex
(PFC), supports the development of episodic memory. Yet how different regions of the PFC …

Emerging studies have emphasized the importance of the fidelity of cortical representation in
forming enduring episodic memory. No study, however, has examined whether there are …

Cognitive neuroimaging studies often report that older adults display more activation of
neural networks relative to younger adults, referred to as overactivation. Greater or more …

Studies investigating the strength and membership of regions within multiple functional
networks primarily focus on either resting state or single cognitive tasks. The goals of the …

It is well documented that older adults recruit additional brain regions compared to those
recruited by younger adults while performing a wide variety of cognitive tasks. However, it is …

Episodic memories are typically composed of perceptual information derived from the
external environment and representations of internal states (eg, one's thoughts during prior …

Prestimulus subsequent memory effects (preSMEs)—differences in neural activity elicited by
a task cue at encoding that are predictive of later memory performance—are thought to …
