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
Integration of Word Meaning and World Knowledge in Language Comprehension
TL;DR: Electroencephalogram data are presented that show the rapid parallel integration of both semantic and world knowledge during the interpretation of a sentence and indicate that the brain keeps a record of what makes a sentence hard to interpret.
Journal ArticleDOI
Declarative memory consolidation in humans: a prospective functional magnetic resonance imaging study.

TL;DR: Over the course of the entire study, hippocampal activity for correct confident recognition continued to decrease, whereas activity in a ventral medial prefrontal region increased, which may prompt a revision of classical consolidation theory, incorporating a transfer of putative linking nodes from hippocampal to prelimbic prefrontal areas.
Journal ArticleDOI
Neuronal Dynamics Underlying High- and Low-Frequency EEG Oscillations Contribute Independently to the Human BOLD Signal
René Scheeringa,René Scheeringa,Pascal Fries,Pascal Fries,Karl Magnus Petersson,Karl Magnus Petersson,Robert Oostenveld,Iris Grothe,David G. Norris,Peter Hagoort,Peter Hagoort,Marcel C. M. Bastiaansen,Marcel C. M. Bastiaansen +12 more
TL;DR: The results indicate that the BOLD-gamma coupling observed in animals can be extrapolated to humans performing a task and that neuronal dynamics underlying high- and low-frequency synchronization contribute independently to the Bold signal.
Journal ArticleDOI
Pain-related cerebral activation is altered by a distracting cognitive task
TL;DR: In this paper, the authors investigated whether attention-related modulations are present in the processing of pain, measuring the regional cerebral blood flow was measured using [(15)O]butanol and positron emission tomography in conditions involving both pain and parallel cognitive demands.
