    Barbara Bucur
    Center for the Study of Aging and Human Development, Duke University Medical Center, USA
    Neurobiol Aging 29:1070-9. 2008

    David J Madden
    Center for the Study of Aging and Human Development, Duke University Medical Center, Durham, NC 27710, USA
    Neuroimage 52:643-57. 2010
    ..These findings highlight the functional connectivity of frontoparietal activation as a potential source of age-related decline in executive control...

    David J Madden
    Duke University Medical Center, Durham, NC 27710, USA
    J Cogn Neurosci 21:289-302. 2009
    ..This result is the first demonstration that the integrity of specific white matter tracts is a mediator of age-related changes in cognitive performance...

    Barbara Bucur
    Center for the Study of Aging and Human Development, Duke University Medical Center, Durham, North Carolina, USA
    Exp Aging Res 36:153-68. 2010

    Bonita L Marks
    Center for the Study of Aging and Human Development, Duke University Medical Center, Durham, North Carolina, USA
    Ann N Y Acad Sci 1097:171-4. 2007
    ..There are only a few studies, however, investigating potential mechanisms for the improvements in aerobic fitness. Our study suggests that greater aerobic fitness may be related to greater WM integrity in select brain regions...

    David J Madden
    Duke University Medical Center, Durham, NC 27710, USA
    Q J Exp Psychol (Hove) 60:644-51. 2007

    Center for the Study of Aging and Human Development, Duke University Medical Center, Durham, NC 27710, USA
    Psychol Aging 20:435-46. 2005
    ..These findings indicate that the coactive processing of redundant visual dimensions is spared in healthy older adults and that for both groups, attention must be focused on both dimensions for coactivation to occur...
