Cortico-Limbic Response to Personally Challenging Emotional Stimuli After Complete Recovery from Depression
(Elsevier, 2009)People vulnerable to depression are at increased risk of relapse if they live in highly critical family environments. To explore this link, we used neuroimaging methods to examine cortico-limbic responding to personal ... -
Enhanced Negative Feedback Responses in Remitted Depression
(Lippincott Williams & Wilkins, 2008)Major depressive disorder (MDD)is characterized by hypersensitivity to negative feedback that might involve frontocingulate dysfunction. MDD patients exhibit enhanced electrophysiological responses to negative internal ... -
Individual Differences in Reinforcement Learning: Behavioral, Electrophysiological, and Neuroimaging Correlates
(Elsevier, 2008)During reinforcement learning, phasic modulations of activity in midbrain dopamine neurons are conveyed to the dorsal anterior cingulate Cortex (dACC) and basal ganglia (BG) and serve to guide adaptive responding. While ... -
Response Conflict and Frontocingulate Dysfunction in Unmedicated Participants with Major Depression
(Pergamon Press, 2008)Individuals with major depressive disorder (MDD) often exhibit impaired executive function, particularly in experimental tasks that involve response conflict and require adaptive behavioral adjustments. Prior research ... -
The Role of the Nucleus Accumbens and Rostral Anterior Cingulate Cortex in Anhedonia: Integration of Resting EEG, fMRI, and Volumetric Techniques
(Elsevier, 2006)Anhedonia, the reduced propensity to experience pleasure, is a promising endo-- phenotype and vulnerability factor for several psychiatric disorders, including depression and schizophrenia. In the present study, we used ... -
Single Dose of a Dopamine Agonist Impairs Reinforcement Learning in Humans: Evidence from Event-related Potentials and Computational Modeling of Striatal-Cortical Function
(Wiley-Blackwell, 2009)Animal findings have highlighted the modulatory role of phasic dopamine (DA) signaling in incentive learning, particularly in the acquisition of reward-related behavior. In humans, these processes remain largely unknown. ...
