ALERT: This system is being upgraded on Tuesday December 12. It will not be available for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace will be disabled on Monday December 11, so no new items are to be added to the repository while the upgrade is in progress. Everything should be back to normal by the end of day, December 12.

    • Age mediation of frontoparietal activation during visual feature search. 

      Madden, David J; Parks, Emily L; Davis, Simon W; Diaz, Michele T; Potter, Guy G; Chou, Ying-hui; Chen, Nan-kuei; ... (8 authors) (Neuroimage, 2014-11-15)
      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 ...
    • Age-related differences in frontoparietal activation for target and distractor singletons during visual search. 

      Merenstein, Jenna L; Mullin, Hollie A; Madden, David J (Attention, perception & psychophysics, 2023-04)
      Age-related decline in visual search performance has been associated with different patterns of activation in frontoparietal regions using functional magnetic resonance imaging (fMRI), but whether these age-related effects ...
    • Brain connectivity and visual attention. 

      Parks, Emily L; Madden, David J (Brain connectivity, 2013-01)
      Emerging hypotheses suggest that efficient cognitive functioning requires the integration of separate, but interconnected cortical networks in the brain. Although task-related measures of brain activity suggest ...
    • Characteristics of sequential activity in networks with temporally asymmetric Hebbian learning. 

      Gillett, Maxwell; Pereira, Ulises; Brunel, Nicolas (Proceedings of the National Academy of Sciences of the United States of America, 2020-11-11)
      Sequential activity has been observed in multiple neuronal circuits across species, neural structures, and behaviors. It has been hypothesized that sequences could arise from learning processes. However, it is still unclear ...
    • Complementary topology of maintenance and manipulation brain networks in working memory. 

      Davis, SW; Crowell, CA; Beynel, L; Deng, L; Lakhlani, D; Hilbig, SA; Lim, W; ... (13 authors) (Scientific reports, 2018-12-13)
      Working memory (WM) is assumed to consist of a process that sustains memory representations in an active state (maintenance) and a process that operates on these activated representations (manipulation). We examined evidence ...
    • Emotion-attention network interactions during a visual oddball task. 

      Fichtenholtz, Harlan M; Dean, Heather L; Dillon, Daniel G; Yamasaki, Hiroshi; McCarthy, Gregory; LaBar, Kevin S (Brain Res Cogn Brain Res, 2004-06)
      Emotional and attentional functions are known to be distributed along ventral and dorsal networks in the brain, respectively. However, the interactions between these systems remain to be specified. The present study used ...
    • Functional parcellation of attentional control regions of the brain. 

      Woldorff, Marty G; Hazlett, Chad J; Fichtenholtz, Harlan M; Weissman, Daniel H; Dale, Anders M; Song, Allen W (J Cogn Neurosci, 2004-01)
      Recently, a number of investigators have examined the neural loci of psychological processes enabling the control of visual spatial attention using cued-attention paradigms in combination with event-related functional magnetic ...
    • Response-level processing during visual feature search: Effects of frontoparietal activation and adult age. 

      Madden, David J; Siciliano, Rachel E; Tallman, Catherine W; Monge, Zachary A; Voss, Andreas; Cohen, Jessica R (Attention, perception & psychophysics, 2020-01)
      Previous research suggests that feature search performance is relatively resistant to age-related decline. However, little is known regarding the neural mechanisms underlying the age-related constancy of feature search. ...
    • Visual perception and corollary discharge. 

      Sommer, Marc A; Wurtz, Robert H (Perception, 2008)
      Perception depends not only on sensory input but also on the state of the brain receiving that input. A classic example is perception of a stable visual world in spite of the saccadic eye movements that shift the images ...
