Journal ArticleDOI
Anhedonia in Trauma-Exposed Individuals: Functional Connectivity and Decision-Making Correlates.
Elizabeth A. Olson,Elizabeth A. Olson,Roselinde H. Kaiser,Diego A. Pizzagalli,Scott L. Rauch,Scott L. Rauch,Isabelle M. Rosso,Isabelle M. Rosso +7 more
TL;DR: Greater anhedonia was related to higher positive connectivity between NAcc and right dorsomedial prefrontal cortex and to increased delay discounting, i.e., greater preference for smaller immediate versus larger delayed rewards.
Journal ArticleDOI
One-year-old fear memories rapidly activate human fusiform gyrus
TL;DR: In both the recent and remote recall tests, fear conditioned faces potentiated rapid activation in proximity of fusiform gyrus, even in participants unaware of the contingencies, suggesting that rapid processing enhancements of conditioned faces persist over time.
Journal ArticleDOI
Optimizing assessments of post-error slowing: A neurobehavioral investigation of a flanker task.
Hans S. Schroder,Hans S. Schroder,Stefanie Nickels,Stefanie Nickels,Emilia Cardenas,Micah Breiger,Sarah Perlo,Diego A. Pizzagalli,Diego A. Pizzagalli +8 more
TL;DR: Using behavioral and electrophysiological data from a modified flanker task, different methods of calculating Post-error slowing were considered, their internal consistency was assessed, and their convergent correlations with behavioral performance and error-related event-related brain potentials (ERPs) were examined.
Journal ArticleDOI
Striatal hypofunction as a neural correlate of mood alterations in chronic pain patients.
Minhae Kim,Ishtiaq Mawla,Daniel S. Albrecht,Roee Admon,Angel Torrado-Carvajal,Courtney Bergan,Ekaterina Protsenko,Poornima Kumar,Robert R. Edwards,Atreyi Saha,Vitaly Napadow,Diego A. Pizzagalli,Marco L. Loggia +12 more
TL;DR: In chronic pain, PA reduction and NA increase are accompanied by striatal hypofunction as measured by the MID task, and this hypothesis relates to mood alterations comorbid with chronic pain.
Journal ArticleDOI
Nicotine normalizes cortico-striatal connectivity in non-smoking individuals with major depressive disorder.
Amy C. Janes,Amy C. Janes,Maya Zegel,Kyoko Ohashi,Kyoko Ohashi,Jennifer Betts,Elena Molokotos,David P. Olson,David P. Olson,Lauren V. Moran,Lauren V. Moran,Diego A. Pizzagalli,Diego A. Pizzagalli +12 more
TL;DR: Results indicate that nicotine normalizes dysfunctional cortico-striatal communication in unmedicated non-smokers with MDD and suggest that nicotinic agents may have therapeutic effects on disrupted cortico’sstriatal connectivity.
