COMT and ANKK1 gene-gene interaction modulates contextual updating of mental representations
The differential expression of the dopamine transmitter through its prefrontostriatal pathway has been proposed to account for individual differences in the updating of higher order task representations. Here we examined the interaction between two polymorphic variations of genes involved in the regulation of prefrontal and striatal dopamine (catechol-O-methyltransferase-COMT and ANKK1) on the ...
متن کاملNegative emotional context enhances auditory novelty processing.
We used an auditory-visual distraction task to investigate the functional relationship between distraction elicited by auditory novel events and a context of negative emotional processing, both at behavioural and electrophysiological (event-related brain potentials) levels in humans. Participants performed a decision task on pictures disclosing sceneries with a task-irrelevant emotional load or...
متن کاملEmotional context enhances auditory novelty processing: behavioural and electrophysiological evidence.
Viewing emotionally negative pictures has been proposed to attenuate brain responses towards sudden auditory events, as more attentional resources are allocated to the affective visual stimuli. However, peripheral reflexes have been shown intensified. These observations have raised the question of whether an emotional context actually facilitates or attenuates processing in the auditory novelty...
متن کاملGene duplication and evolutionary novelty in plants.
Duplication is a prominent feature of plant genomic architecture. This has led many researchers to speculate that gene duplication may have played an important role in the evolution of phenotypic novelty within plants. Until recently, however, it was difficult to make this connection. We are now beginning to understand how duplication has contributed to adaptive evolution in plants. In this rev...
متن کاملNovelty Processing in Human Robot Interaction
Our interest is pragmatic, driven by our engineering research culture; we want to break down the barriers to human-robot interaction, enabling people to communicate their wishes to subservient robots. It is notoriously difficult for humans to get machines and computers to understand and carry out tasks on behalf of the users. Normally many hours, much expertise and considerable funds are needed...
