| Abstract |
Although alcohol consumption is linked to increased aggression, its neural correlates have not directly been studied in humans so far. Based on a comprehensive neurobiological model of alcohol-induced aggression, we hypothesized that alcohol-induced aggression would go along with increased amygdala and ventral striatum reactivity and impaired functioning of the prefrontal cortex (PFC) under alcohol. We measured neural and behavioral correlates of alcohol-induced aggression in a provoking versus non-provoking condition with a variant of the Taylor aggression paradigm (TAP) allowing to differentiate between reactive (provoked) and proactive (unprovoked) aggression. In a placebo-controlled cross-over design with moderate alcohol intoxication (~0.6 g/kg), thirty-five young healthy adults performed the TAP during functional magnetic resonance imaging (fMRI). Analyses revealed that provoking versus non-provoking conditions and alcohol versus placebo increased aggression, and decreased brain responses in the anterior cingulate cortex/dorso-medial PFC (provoking<non-provoking), and the ventral striatum (alcohol<placebo) across our healthy sample. Interestingly, alcohol specifically increased pro-active (unprovoked) but not reactive (provoked) aggression (alcohol x provocation interaction). However, investigation of inter-individual differences revealed (1) that pronounced alcohol-induced pro-active aggression was linked to higher levels of aggression under placebo, and (2) that pronounced alcohol-induced reactive aggression was related to increased amygdala and ventral striatum reactivity under alcohol, providing evidence for their role in human alcohol-induced reactive aggression. Our findings suggest that in healthy young adults a liability for alcohol-induced aggression in a non-provoking context might depend on overall high levels of aggression, but on alcohol-induced increased striatal and amygdala reactivity when triggered by provocation.Neuropsychopharmacology accepted article preview online, 14 May 2015. doi:10.1038/npp.2015.141. |

Attention Score in Context
This research output has an Altmetric Attention Score of 30. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 November 2023.
All research outputs
#1,262,088
of 24,795,084 outputs
Outputs from Neuropsychopharmacology
#560
of 4,384 outputs
Outputs of similar age
#15,719
of 269,526 outputs
Outputs of similar age from Neuropsychopharmacology
#10
of 105 outputs
Altmetric has tracked 24,795,084 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 94th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,384 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 20.8. This one has done well, scoring higher than 87% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 269,526 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 94% of its contemporaries.
We're also able to compare this research output to 105 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 91% of its contemporaries.
