    Ruth M Krebs
    Department of Neurology, Otto von Guericke University, Magdeburg, Germany
    PLoS ONE 5:e8691. 2010
    ..The knowledge about the function of this structure is mainly based on single-unit recordings in animals with relatively few neuroimaging studies investigating eye-movement related brain activity in humans...
  2. pmc The influence of reward associations on conflict processing in the Stroop task
    Ruth M Krebs
    Center for Cognitive Neuroscience, Duke University, Durham, NC 27708, USA
    Cognition 117:341-7. 2010
    ..These observations imply that the prospect of reward enhances the processing of task-relevant stimulus information, whereas incongruent reward-related information in a task-irrelevant dimension can impede task performance...
  3. pmc Reward associations reduce behavioral interference by changing the temporal dynamics of conflict processing
    Ruth M Krebs
    Center for Cognitive Neuroscience, Duke University, Durham, North Carolina, United States of America
    PLoS ONE 8:e53894. 2013
    ..Taken together, the present data demonstrate that reward associations can influence conflict processing by changing the temporal dynamics of stimulus processing and subsequent cognitive-control mechanisms...

    Carsten Nicolas Boehler
    Leibniz Institute for Neurobiology, Magdeburg, Germany
    J Cogn Neurosci 23:362-73. 2011
    ..This SN-based modulatory mechanism is presumably mediated via a wider network that determines response speed in this task, including frontal and parietal control regions, along with the BG and the associated subthalamic nucleus...

    C Nicolas Boehler
    Center for Cognitive Neuroscience, Duke University, Durham, NC, USA
    Behav Brain Res 229:123-30. 2012
    ..In sum, the current results highlight that different SSRT-estimation procedures can strongly influence the distribution of SSRT values across subjects, which in turn can ramify into correlational analyses with other parameters...

    PLoS ONE 6:e26386. 2011
    ..Activity profiles in frontal areas, in turn, were activated mainly by task-relevant Stop-trials, presumably reflecting a combination of triggered top-down attentional influences and inhibitory motor-control processes...
