Frontoparietal activation during visual conjunction search: Effects of bottom-up guidance and adult age.
(Hum Brain Mapp, 2017-04)We conducted functional magnetic resonance imaging (fMRI) with a visual search paradigm to test the hypothesis that aging is associated with increased frontoparietal involvement in both target detection and bottom-up attentional ... -
Sources of disconnection in neurocognitive aging: cerebral white-matter integrity, resting-state functional connectivity, and white-matter hyperintensity volume.
(Neurobiol Aging, 2017-06)Age-related decline in fluid cognition can be characterized as a disconnection among specific brain structures, leading to a decline in functional efficiency. The potential sources of disconnection, however, are unclear. ... -
Task difficulty modulates brain activation in the emotional oddball task.
(Brain Res, 2017-06-01)Previous functional magnetic resonance imaging (fMRI) studies have reported that task-irrelevant, emotionally salient events can disrupt target discrimination, particularly when attentional demands are low, while others ...
