An unbalanced distribution of inputs across the hemispheres facilitates interhemispheric interactionD H Weissman
Center for Cognitive Neuroscience, Duke University, Durham, NC 27708, USA
J Int Neuropsychol Soc 6:313-21. 2000..These results indicate that IHI facilitates performance by allowing (1) a division of processing across the hemispheres, and (2) task-relevant information to be processed by a hemisphere that receives a relatively light processing load...- The neural bases of momentary lapses in attentionD H Weissman
Center for Cognitive Neuroscience and Department of Psychiatry, Duke University, Durham, North Carolina 27708, USA
Nat Neurosci 9:971-8. 2006..Our findings provide a new, system-wide understanding of the patterns of brain activity that are associated with brief attentional lapses, which informs both theoretical and clinical models of goal-directed behavior... - The neural mechanisms for minimizing cross-modal distractionD H Weissman
Center for Cognitive Neuroscience, Duke University, Durham, North Carolina 27708, USA
J Neurosci 24:10941-9. 2004..Furthermore, they potentially resolve a long-standing controversy regarding the key contribution of the ACC to cognitive control... - Hemispheric asymmetries for different components of global/local attention occur in distinct temporo-parietal lociD H Weissman
Center for Cognitive Neuroscience, Duke University, Durham, NC 27708, USA
Cereb Cortex 15:870-6. 2005..Furthermore, it parallels an analogous dissociation reported in a recent fMRI study of spatial orienting, suggesting that global/local attention and spatial attention might rely on similar cognitive/neural mechanisms... - Dorsal anterior cingulate cortex resolves conflict from distracting stimuli by boosting attention toward relevant eventsD H Weissman
Center for Cognitive Neuroscience, Duke University, Durham, NC 27708, USA
Cereb Cortex 15:229-37. 2005..Our findings indicate a role for dACC in focusing attention on behaviorally relevant stimuli, especially when the achievement of our behavioral goals is threatened by distracting events... - Conflict monitoring in the human anterior cingulate cortex during selective attention to global and local object featuresD H Weissman
Center for Cognitive Neuroscience and Department of Psychological and Brain Sciences, Duke University, Box 90999, Durham, NC 27708, USA
Neuroimage 19:1361-8. 2003.... - Effects of practice on executive control investigated with fMRID H Weissman
Center for Cognitive Neuroscience and Department of Psychological and Brain Sciences, Duke University, Box 90999, Durham, NC 27708, USA
Brain Res Cogn Brain Res 15:47-60. 2002..These findings support models of executive control in which practice increases the tendency for stimuli to automatically evoke task-relevant processes and responses... - The neural circuitry underlying the executive control of auditory spatial attentionC T Wu
Center for Cognitive Neuroscience, Department of Psychology and Neurosciences, Duke University, Durham, NC 27708, USA
Brain Res 1134:187-98. 2007.... - Functional parcellation of attentional control regions of the brainMarty G Woldorff
Center for Cognitive Neuroscience, Room B203, Duke University, LSRC Building, Box 90999, Durham, NC 27708 0999, USA
J Cogn Neurosci 16:149-65. 2004..Additional cue-related effects included differential activations in midline frontal regions and pretarget enhancements in the thalamus and early visual cortical areas... - The spread of attention across modalities and space in a multisensory objectLaura Busse
Center for Cognitive Neuroscience and Department of Psychiatry, Duke University, Durham, NC 27708, USA
Proc Natl Acad Sci U S A 102:18751-6. 2005.... - Brain regions activated by endogenous preparatory set shifting as revealed by fMRIH A Slagter
Duke University, Durham, North Carolina, USA
Cogn Affect Behav Neurosci 6:175-89. 2006..Furthermore, they demonstrate that global task structure is a critical determinant of whether switch-specific preparatory activity is observed... - A role for top-down attentional orienting during interference between global and local aspects of hierarchical stimuliD H Weissman
Center for Congnitive Neuroscience, Duke University, Durham, North Carolina 27708, USA
Neuroimage 17:1266-76. 2002..These findings support models in which conflict between target and distracter stimuli is resolved by more selectively focusing attention upon target stimuli... - Attention-related activity during episodic memory retrieval: a cross-function fMRI studyRoberto Cabeza
Center for Cognitive Neuroscience, Duke University, PO Box 90999, LSRC Bldg, Rm B203, Durham, NC 27708, USA
Neuropsychologia 41:390-9. 2003..Overall, the present results suggest that many of the activations attributed to specific cognitive processes, such as episodic memory, may actually reflect more general cognitive operations... - Interhemispheric integration in psychopathic offendersMabel Lopez
Department of Psychology, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA
Neuropsychology 21:82-93. 2007..Analyses indicated that psychopathic offenders are not deficient in interhemispheric integration but provided additional evidence consistent with the left hemisphere activation hypothesis of psychopathy... - Pre-target activity in visual cortex predicts behavioral performance on spatial and feature attention tasksBarry Giesbrecht
Department of Psychology, University of California, Santa Barbara, CA 93106 9660, USA
Brain Res 1080:63-72. 2006..These findings support the view that top-down control systems bias activity in sensory cortices to favor the processing of expected target features and that this bias is related to behavior... - A hemispheric division of labor aids mental rotationKazuhito Yoshizaki
Department of Psychology and Communication, Aichi Shukutoku University, Aichi, Japan
Neuropsychology 21:326-36. 2007..These findings support a current model of hemispheric interactions, which posits that an unequal hemispheric distribution of cognitive load allows the cerebral hemispheres to take the lead for different aspects of cognitive processing... - Lapsing during sleep deprivation is associated with distributed changes in brain activationMichael W L Chee
Cognitive Neuroscience Laboratory, Duke National University of Singapore Graduate Medical School, Singapore
J Neurosci 28:5519-28. 2008..These findings reveal for the first time some of the neural consequences of the interaction between efforts to maintain wakefulness and processes that initiate involuntary sleep in sleep-deprived persons...
