Recent data from animal studies raise the possibility that dopaminergic neuromodulation
promotes the encoding of novel stimuli. We investigated a possible role for the dopaminergic …

Most studies investigating semantic memory have focused on taxonomic or associative relations.
Little is known about how other relations, such as causal relations, are represented and …

Exploring a novel environment can facilitate subsequent hippocampal long-term potentiation
in animals. We report a related behavioral enhancement in humans. In two separate …

The amygdala is thought to enhance long‐term memory for emotionally arousing events by
modulating memory formation and storage in the hippocampus and in neocortical areas. …

New episodic memory traces represent a record of the ongoing neocortical processing
engaged during memory formation (encoding). Thus, during encoding, deep (semantic) …

The capacity to evaluate causal relations is fundamental to human cognition, and yet little is
known of its neurocognitive underpinnings. A functional magnetic resonance imaging study …

Faces expressing fear may attract attention in an automatic bottom–up fashion. Here we
address this issue with magneto-encephalographic (MEG) recordings in subjects performing a …

Abstract Knowledge about cause and effect relationships (eg, virus–epidemic) is essential
for predicting changes in the environment and for anticipating the consequences of events …

BACKGROUND: Declarative memory disturbances, known to substantially contribute to
cognitive impairment in schizophrenia, have previously been attributed to prefrontal as well as …

Perception and practice of violence have hedonistic aspects associated with positive
arousal (appetitive aggression). Earlier studies have mainly investigated the aetiology of …
