    The dynamics of proactive and reactive cognitive control processes in the human brain. 

    Appelbaum, Lawrence Gregory; Boehler, CN; Davis, LA; Woldorff, Marty G; Won, RJ (J Cogn Neurosci, 2014-05)
    In this study, we leveraged the high temporal resolution of EEG to examine the neural mechanisms underlying the flexible regulation of cognitive control that unfolds over different timescales. We measured behavioral and ...

    The neural dynamics of stimulus and response conflict processing as a function of response complexity and task demands. 

    Appelbaum, Lawrence Gregory; Donohue, Sarah; McKay, CC; Woldorff, Marty G (Neuropsychologia, 2016-04)
    Both stimulus and response conflict can disrupt behavior by slowing response times and decreasing accuracy. Although several neural activations have been associated with conflict processing, it is unclear how specific any ...

    Rapid modulation of sensory processing induced by stimulus conflict. 

    Appelbaum, Lawrence Gregory; Boehler, CN; Chen, WD; Smith, DV; Woldorff, Marty G (J Cogn Neurosci, 2011-09)
    Humans are constantly confronted with environmental stimuli that conflict with task goals and can interfere with successful behavior. Prevailing theories propose the existence of cognitive control mechanisms that can suppress ...

    The role of stimulus salience and attentional capture across the neural hierarchy in a stop-signal task. 

    Appelbaum, Lawrence Gregory; Boehler, CN; Chen, LC; Krebs, Ruth M; Woldorff, Marty G (PLoS One, 2011)
    Inhibitory motor control is a core function of cognitive control. Evidence from diverse experimental approaches has linked this function to a mostly right-lateralized network of cortical and subcortical areas, wherein a ...

    Differential developmental trajectories of magnetic susceptibility in human brain gray and white matter over the lifespan. 

    Bancroft-Wu, V; Batrachenko, A; De Bellis, MD; Langkammer, C; Li, W; Liu, C; Morey, Rajendra A; ... (11 authors) (Hum Brain Mapp, 2014-06)
    As indicated by several recent studies, magnetic susceptibility of the brain is influenced mainly by myelin in the white matter and by iron deposits in the deep nuclei. Myelination and iron deposition in the brain evolve ...

    Improvement in visual search with practice: mapping learning-related changes in neurocognitive stages of processing. 

    Appelbaum, Lawrence Gregory; Clark, K; Mitroff, Stephen; van den Berg, Berry; Woldorff, Marty G (J Neurosci, 2015-04-01)
    Practice can improve performance on visual search tasks; the neural mechanisms underlying such improvements, however, are not clear. Response time typically shortens with practice, but which components of the stimulus-response ...

    Cortical Brain Activity Reflecting Attentional Biasing Toward Reward-Predicting Cues Covaries with Economic Decision-Making Performance. 

    Appelbaum, Lawrence Gregory; Huettel, Scott; San Martín, R; Woldorff, Marty G (Cereb Cortex, 2016-01)
    Adaptive choice behavior depends critically on identifying and learning from outcome-predicting cues. We hypothesized that attention may be preferentially directed toward certain outcome-predicting cues. We studied this ...

    The influence of different Stop-signal response time estimation procedures on behavior-behavior and brain-behavior correlations. 

    Appelbaum, Lawrence Gregory; Boehler, CN; Hopf, JM; Krebs, Ruth M; Woldorff, Marty G (Behav Brain Res, 2012-04-01)
    The fundamental cognitive-control function of inhibitory control over motor behavior has been extensively investigated using the Stop-signal task. The critical behavioral parameter describing stopping efficacy is the Stop-signal ...

    Effects of chronic mild traumatic brain injury on white matter integrity in Iraq and Afghanistan war veterans. 

    Cernak, I; Haswell, CC; Liu, C; Marx, Christine Elizabeth; Massoglia, D; McCarthy, G; MIRECC Work Group; ... (10 authors) (Hum Brain Mapp, 2013-11)
    Mild traumatic brain injury (TBI) is a common source of morbidity from the wars in Iraq and Afghanistan. With no overt lesions on structural MRI, diagnosis of chronic mild TBI in military veterans relies on obtaining an ...

    Functional neuroimaging of emotionally intense autobiographical memories in post-traumatic stress disorder. 

    Botzung, A; Miles, A; Rubin, David C; St Jacques, PL (J Psychiatr Res, 2011-05)
    Post-traumatic stress disorder (PTSD) affects regions that support autobiographical memory (AM) retrieval, such as the hippocampus, amygdala and ventral medial prefrontal cortex (PFC). However, it is not well understood ...
