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 ...
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 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 ...
