abstract = {There is considerable evidence that emotion dysregulation
and self-control impairments lead to escalated aggression in
populations with psychiatric disorders. However, convergent
quantitative evidence on the neural network explaining how
aggression arises is still lacking. To address this gap,
peak activations extracted from extant functional magnetic
resonance imaging (fMRI) studies were synthesized through
coordinate-based meta-analyses. A systematic search in the
PubMed database was conducted and 26 fMRI studies met the
inclusion criteria. Three separate activation likelihood
estimation (ALE) meta-analyses were performed on (1)
individual differences in trait aggression (TA) studies, (2)
individual differences in TA studies examining executive
functioning, and (3) elicited aggression (EA) studies across
fMRI behavioral paradigms. Ensuing clusters from ALE
meta-analyses were further treated as seeds for follow-up
investigations on consensus connectivity networks (CCN)
delineated from meta-analytic connectivity modeling (MACM)
and resting-state functional connectivity (RSFC) to further
characterize their physiological functions. Finally, we
obtained a data-driven functional characterization of the
ensuing clusters and their networks. This approach offers a
boarder view of the ensuing clusters using a boarder network
perspective. In TA, aberrant brain activations were found
only in the right precuneus. Follow-up analyses revealed
that the precuneus seed was within the frontal-parietal
network (FPN) associated with action inhibition,
visuospatial processing and higher-level cognition. With
further restricting to only experiments examining executive
functioning, convergent evidence was found in the right
rolandic operculum (RO), midcingulate cortex (MCC),
precentral gyrus (PrG) and precuneus. Follow-up analyses
suggested that RO, MCC and PrG may belong to a common
cognitive control network, while the MCC seems to be the hub
of this network. In EA, we only revealed a convergent region
in the left postcentral gyrus. Follow-up CCN analyses and
functional characterizations suggested that this region may
also belong to the same cognitive control network found in
the TA sub-analysis. Our results suggested that escalated
aggression arises from abnormal precuneus activities within
the FPN, disrupting the recruitment of other large-scale
networks such as adaptive cognitive control network.
Consequently, failure to recruit such a network results in
an inability to generate adaptive responses, increasing the
likelihood of acting aggressively.},
