Journal ArticleDOI
Placebo and opioid analgesia - Imaging a shared neuronal network
TL;DR: Using positron emission tomography, it is confirmed that both opioid and placebo analgesia are associated with increased activity in the rostral anterior cingulate cortex and the brainstem, indicating a related neural mechanism in placebo and opioid analgesia.
Journal ArticleDOI
When Fear Is Near: Threat Imminence Elicits Prefrontal-Periaqueductal Gray Shifts in Humans
Dean Mobbs,Predrag Petrovic,Jennifer L. Marchant,Demis Hassabis,Nikolaus Weiskopf,Ben Seymour,Raymond J. Dolan,Chris D. Frith +7 more
TL;DR: Using functional magnetic resonance imaging, it is found that as the virtual predator grew closer, brain activity shifted from the ventromedial prefrontal cortex to the periaqueductal gray, and showed maximal expression when a high degree of pain was anticipated.
Journal ArticleDOI
The Predictive Coding Account of Psychosis
Philipp Sterzer,Rick A. Adams,Paul C. Fletcher,Chris D. Frith,Stephen M. Lawrie,Lars Muckli,Predrag Petrovic,Peter J. Uhlhaas,Martin Voss,Philip R. Corlett +9 more
TL;DR: The current evidence for aberrant predictive coding is reviewed and challenges for this canonical predictive coding account of psychosis are discussed, portending a framework for psychosis more equipped to deal with its many manifestations.
Journal ArticleDOI
Oxytocin Attenuates Affective Evaluations of Conditioned Faces and Amygdala Activity
TL;DR: The data suggest that oxytocin modulates the expression of evaluative conditioning for socially relevant faces via influences on amygdala and fusiform gyrus, an effect that may explain its prosocial effects.
Journal ArticleDOI
Placebo in Emotional Processing— Induced Expectations of Anxiety Relief Activate a Generalized Modulatory Network
Predrag Petrovic,Thomas Dietrich,Peter Fransson,Jesper L. R. Andersson,Katrina Carlsson,Martin Ingvar +5 more
TL;DR: The behavioral part of this study indicates that placebo treatment has an effect on how subjects perceive unpleasant pictures and event-related fMRI demonstrated that the same modulatory network, including the rostral anterior cingulate cortex and the lateral orbitofrontal cortex, is involved in both emotional placebo and placebo analgesia.
