Resting-state networks do not determine cognitive function networks: a commentary on Campbell and Schacter (2016)
(Language, Cognition and Neuroscience, 2016-11-08)
Age mediation of frontoparietal activation during visual feature search.
Activation of frontal and parietal brain regions is associated with attentional control during visual search. We used fMRI to characterize age-related differences in frontoparietal activation in a highly efficient feature ...
Less wiring, more firing: low-performing older adults compensate for impaired white matter with greater neural activity.
(Cereb Cortex, 2015-04)
The reliable neuroimaging finding that older adults often show greater activity (over-recruitment) than younger adults is typically attributed to compensation. Yet, the neural mechanisms of over-recruitment in older adults ...
Age-related effects on the neural correlates of autobiographical memory retrieval.
(Neurobiol Aging, 2012-07)
Older adults recall less episodically rich autobiographical memories (AM), however, the neural basis of this effect is not clear. Using functional MRI, we examined the effects of age during search and elaboration phases ...
Mental hoop diaries: emotional memories of a college basketball game in rival fans.
(J Neurosci, 2010-02-10)
The rivalry between the men's basketball teams of Duke University and the University of North Carolina-Chapel Hill (UNC) is one of the most storied traditions in college sports. A subculture of students at each university ...
Neural correlates of emotional processing in depression: changes with cognitive behavioral therapy and predictors of treatment response.
(J Psychiatr Res, 2011-05)
Major depressive disorder (MDD) is characterized by the presence of disturbances in emotional processing. However, the neural correlates of these alterations, and how they may be affected by therapeutic interventions, remain ...
Adult age differences in functional connectivity during executive control.
Task switching requires executive control processes that undergo age-related decline. Previous neuroimaging studies have identified age-related differences in brain activation associated with global switching effects (dual-task ...
The neural basis of involuntary episodic memories.
(J Cogn Neurosci, 2014-10)
Voluntary episodic memories require an intentional memory search, whereas involuntary episodic memories come to mind spontaneously without conscious effort. Cognitive neuroscience has largely focused on voluntary memory, ...
The architecture of cross-hemispheric communication in the aging brain: linking behavior to functional and structural connectivity.
(Cereb Cortex, 2012-01)
Contralateral recruitment remains a controversial phenomenon in both the clinical and normative populations. To investigate the neural correlates of this phenomenon, we explored the tendency for older adults to recruit prefrontal ...
Cross-hemispheric collaboration and segregation associated with task difficulty as revealed by structural and functional connectivity.
(J Neurosci, 2015-05-27)
Although it is known that brain regions in one hemisphere may interact very closely with their corresponding contralateral regions (collaboration) or operate relatively independent of them (segregation), the specific brain ...
