Association between increased magnetic susceptibility of deep gray matter nuclei and decreased motor function in healthy adults.
(Neuroimage, 2015-01-15)In the human brain, iron is more prevalent in gray matter than in white matter, and deep gray matter structures, particularly the globus pallidus, putamen, caudate nucleus, substantia nigra, red nucleus, and dentate nucleus, ... -
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 ... -
Functional brain connectivity and cognition: effects of adult age and task demands.
(Neurobiology of aging, 2013-08)Previous neuroimaging research has documented that patterns of intrinsic (resting state) functional connectivity (FC) among brain regions covary with individual measures of cognitive performance. Here, we examined the relation ... -
Maintenance and Representation of Mind Wandering during Resting-State fMRI.
(Scientific reports, 2017-01-12)Major advances in resting-state functional magnetic resonance imaging (fMRI) techniques in the last two decades have provided a tool to better understand the functional organization of the brain both in health and illness. ... -
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. ...
