Human cognition is increasingly characterized as an emergent property of interactions
among distributed, functionally specialized brain networks. We recently demonstrated that the …

Studies of neurocognitive aging report altered patterns of brain activity in older versus
younger adults performing executive function tasks. We review the extant literature, using …

Autobiographical memory comprises episodic and semantic components mediated by
dissociable states of consciousness, one promoting the experience of the self at a specific …

Humans survive and thrive through social exchange. Yet, social dependency also comes at
a cost. Perceived social isolation, or loneliness, affects physical and mental health, cognitive …

Cognitive aging is often described in the context of loss or decline. Emerging research
suggests that the story is more complex, with older adults showing both losses and gains in …

We examined whether facial emotion perception was compromised in adults with recent
traumatic brain injury (TBI). Few studies have examined emotion perception in TBI; those that …

Substantial neuroimaging evidence suggests that spontaneous engagement of the default
network impairs performance on tasks requiring executive control. We investigated whether …

Reduced executive control is a hallmark of neurocognitive aging. Poor modulation of lateral
pFC activity in the context of increasing task challenge in old adults and a “failure to …

Significant progress has been made uncovering functional brain networks, yet little is known
about the corresponding structural covariance networks. The default network's functional …

Research has shown that personal memory technologies are a promising way to address
the needs of older adults with memory impairments. In this article, we review three recently …
