Electrophysiological responses to errors and feedback in the process of action regulationPhan Luu
Electrical Geodesics, Inc, Eugene, Oregon 97403, USA
Psychol Sci 14:47-53. 2003..These results suggest that action regulation by the cingulate gyrus may require the entrainment of multiple structures of the Papez corticolimbic circuit...- Medial frontal cortex in action monitoringP Luu
Department of Psychology, University of Oregon, Eugene, Oregon 97403, USA
J Neurosci 20:464-9. 2000..The results also show a linear increase in the amplitude of the ERN with increasingly late responses. These data suggest that frontal networks provide dynamic representations that monitor and evaluate the unfolding action plan... - Mood, personality, and self-monitoring: negative affect and emotionality in relation to frontal lobe mechanisms of error monitoringP Luu
Department of Psychology, University of Oregon, Eugene 97403, USA
J Exp Psychol Gen 129:43-60. 2000..As the high-NA and -NEM participants disengaged from the task, the amplitude of the ERN decreased. These results reveal that affective distress and associated behavioral patterns are closely related with frontal lobe executive functions... - Regulating action: alternating activation of midline frontal and motor cortical networksP Luu
Department ofPsychology, University of Oregon, Eugene, OR 97403, USA
Clin Neurophysiol 112:1295-306. 2001..The nature of these electrical fields and how they are related to cortical areas involved in response execution remains to be clarified... - Frontal midline theta and the error-related negativity: neurophysiological mechanisms of action regulationPhan Luu
Electrical Geodesics, Inc, 1600 Millrace Dr Suite 307, Eugene, OR 97403, USA
Clin Neurophysiol 115:1821-35. 2004..Our previous analyses of ERP and EEG data suggested that the ERN is dominated by partial phase-locking of intermittent theta-band EEG activity. In this paper, this possibility is further evaluated... - Mood and spatial memory: emotion and right hemisphere contribution to spatial cognitionD M Tucker
Psychology, University of Oregon, Eugene 97403, USA
Biol Psychol 50:103-25. 1999..Motivation may be important to this frontal effect: It was enhanced for subjects describing themselves as high in either positive or negative affective arousal during the task... - Scalp electrode impedance, infection risk, and EEG data qualityT C Ferree
Electrical Geodesics, Inc, Riverfront Research Park, 1850 Millrace Dr, OR 97403, Eugene, USA
Clin Neurophysiol 112:536-44. 2001..The present study was designed to evaluate the effect of electrode-scalp impedance on EEG data quality... - Localizing acute stroke-related EEG changes: assessing the effects of spatial undersamplingP Luu
Electrical Geodesics, Inc, Eugene, OR 97403, USA
J Clin Neurophysiol 18:302-17. 2001..The EEG provides useful information about the localization of acute cerebral ischemia, but recording densities of 64 channels or higher are required for accurate spatial characterization of focal stroke-related EEG changes... - Dynamics of task sets: evidence from dense-array event-related potentialsCatherine Poulsen
University of Oregon, Eugene, OR 97403, USA
Brain Res Cogn Brain Res 24:133-54. 2005..In contrast, the centroparietal P3b and N384 effects related to the contextual ambiguity of bivalent trials are consistent with the context monitoring and updating functions associated with the posterior cingulate learning circuit... - Frontolimbic response to negative feedback in clinical depressionDon M Tucker
Department of Psychology, University of Oregon, Eugene, OR, USA
J Abnorm Psychol 112:667-78. 2003..Localization analyses suggested that negative feedback engaged sources in the anterior cingulate and insular cortices. These results suggest that moderate depression may sensitize limbic networks to respond strongly to aversive events... - Neural mechanisms for learning actions in contextPhan Luu
Electrical Geodesics, Inc, 1600 Millrace Dr Suite 307, Eugene, OR 97403, USA
Brain Res 1179:89-105. 2007..Although preliminary, these findings suggest that the specific mechanisms of learning in animal neurophysiology studies may prove informative for understanding the neural basis of human learning and executive cognitive control... - Corticolimbic mechanisms in emotional decisionsDon M Tucker
Department of Psychology, University of Oregon and Electrical Geodesics, Inc, Eugene 97403, USA
Emotion 3:127-49. 2003..An evaluative decision thus begins by recruiting motivational and semantic influences within limbic networks, and these influences appear to shape the development of the decision within multiple neocortical regions... - Geodesic photogrammetry for localizing sensor positions in dense-array EEGGerald S Russell
Electrical Geodesics Inc, Eugene, OR 97403, USA
Clin Neurophysiol 116:1130-40. 2005..56 mm). CONCLUSIONS: Accurate determination of 3D sensor positions can be accomplished with minimal demands on the time of the subject and the experimenter using the photogrammetric method... - Love hurts: the evolution of empathic concern through the encephalization of nociceptive capacityDon M Tucker
Electrical Geodesics, Inc, University of Oregon, Eugene 97403, USA
Dev Psychopathol 17:699-713. 2005.... - Discharges in ventromedial frontal cortex during absence spellsDon M Tucker
Electrical Geodesics, Inc, Riverfront Research Park, 1600 Millrace Drive, Suite 307, Eugene, OR 97403, USA
Epilepsy Behav 11:546-57. 2007..Disrupted in absence, this circuit appears to regulate important aspects of the voluntary control of conscious attention... - Anterior cingulate cortex regulation of sympathetic activityPhan Luu
Brain 126:2119-20. 2003
