Introduction: Obsessive-compulsive disorder (OCD) has been associated with abnormal brain activation in regions related to response inhibition, such as the dorsal anterior cingulate cortex (dACC), as well as dysregulation of the glutamate system. We

BACKGROUND: The dorsal anterior cingulate cortex (dACC) plays an important role in the pathophysiology of obsessive-compulsive disorder (OCD) due to its role in error processing, cognitive control and emotion regulation. OCD patients have shown alter

Increased amygdala and visual cortex activity and functional connectivity towards stimulus novelty is associated with state anxiety.

Autor: Olga T Ousdal, Ole A Andreassen, Andres Server, Jimmy Jensen

Publikováno v: PLoS ONE, Vol 9, Iss 4, p e96146 (2014)

Novel stimuli often require a rapid reallocation of sensory processing resources to determine the significance of the event, and the appropriate behavioral response. Both the amygdala and the visual cortex are central elements of the neural circuitry

Dissociable Effects of Serotonin and Dopamine on the Valuation of Harm in Moral Decision Making

Autor: Molly J, Crockett, Jenifer Z, Siegel, Zeb, Kurth-Nelson, Olga T, Ousdal, Giles, Story, Carolyn, Frieband, Johanna M, Grosse-Rueskamp, Peter, Dayan, Raymond J, Dolan

Publikováno v: Current Biology

Summary An aversion to harming others is a core component of human morality and is disturbed in antisocial behavior [1–4]. Deficient harm aversion may underlie instrumental and reactive aggression, which both feature in psychopathy [5]. Past work h

Association of Neural and Emotional Impacts of Reward Prediction Errors With Major Depression

Autor: Robb B, Rutledge, Michael, Moutoussis, Peter, Smittenaar, Peter, Zeidman, Tanja, Taylor, Louise, Hrynkiewicz, Jordan, Lam, Nikolina, Skandali, Jenifer Z, Siegel, Olga T, Ousdal, Gita, Prabhu, Peter, Dayan, Peter, Fonagy, Raymond J, Dolan

Publikováno v: JAMA psychiatry. 74(8)

Major depressive disorder (MDD) is associated with deficits in representing reward prediction errors (RPEs), which are the difference between experienced and predicted reward. Reward prediction errors underlie learning of values in reinforcement lear

Dopamine Increases a Value-Independent Gambling Propensity

Autor: Francesco, Rigoli, Robb B, Rutledge, Benjamin, Chew, Olga T, Ousdal, Peter, Dayan, Raymond J, Dolan

Publikováno v: Neuropsychopharmacology

Although the impact of dopamine on reward learning is well documented, its influence on other aspects of behavior remains the subject of much ongoing work. Dopaminergic drugs are known to increase risk-taking behavior, but the underlying mechanisms f
