Patterns of Brain Activation when Mothers View Their Own Child and Dog: An fMRI Study
Stoeckel, Luke E.; Palley, Lori S.; Gollub, Randy L.; Niemi, Steven M.; Evins, Anne Eden (Public Library of Science, 2014)Neural substrates underlying the human-pet relationship are largely unknown. We examined fMRI brain activation patterns as mothers viewed images of their own child and dog and an unfamiliar child and dog. There was a common ... -
Single Dose of a Dopamine Agonist Impairs Reinforcement Learning in Humans: Behavioral Evidence from a Laboratory-based Measure of Reward Responsiveness
Pizzagalli, Diego A; Evins, Anne; Schetter, Erika Cowman; Frank, Michael J.; Pajtas, Petra E.; Santesso, Diane L.; Culhane, Melissa (Springer Verlag, 2008)Rationale. The dopaminergic system, particularly D2-like dopamine receptors, has been strongly implicated in reward processing. Animal studies have emphasized the role of phasic dopamine (DA) signaling in reward-related ... -
Single Dose of a Dopamine Agonist Impairs Reinforcement Learning in Humans: Evidence from Event-related Potentials and Computational Modeling of Striatal-Cortical Function
Santesso, Diane L.; Evins, Anne Eden; Frank, Michael J.; Schetter, Erika M. Cowman; Bogdan, Ryan; Pizzagalli, Diego A (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. ... -
A Single Dose of Nicotine Enhances Reward Responsiveness in Nonsmokers: Implications for Development of Dependence
Goff, Donald; Pizzagalli, Diego; Evins, Anne; Goff, Donald C.; Culhane, Melissa A.; Barr, Ruth S. (Elsevier, 2008)Background: Tobacco smoking, driven by the addictive properties of nicotine, is the most prevalent preventable cause of death in the Western world. Accumulated evidence suggests that nicotine may increase appetitive ...
