abstract = {Background: Over the past few decades, neuroimaging
research in Bipolar Disorder (BD) has identified neural
differences underlying cognitive and emotional processing.
However, substantial clinical and methodological
heterogeneity present across neuroimaging experiments
potentially hinders the identification of consistent neural
biomarkers of BD. This meta-analysis aims to comprehensively
reassess brain activation and connectivity in BD in order to
identify replicable differences that converge across and
within resting-state, cognitive, and emotional neuroimaging
experiments.Methods: Neuroimaging experiments (using fMRI,
PET, or arterial spin labeling) reporting whole-brain
results in adults with BD and controls published from
December 1999-June 18, 2019 were identified via PubMed
search. Coordinates showing significant activation and/or
connectivity differences between BD participants and
controls during resting-state, emotional, or cognitive tasks
were extracted. Four parallel, independent meta-analyses
were calculated using the revised activation likelihood
estimation algorithm: all experiment types, all
resting-state experiments, all cognitive experiments, and
all emotional experiments. To confirm reliability of
identified clusters, two different meta-analytic
significance tests were employed.Results: 205 published
studies yielding 506 individual neuroimaging experiments
(150 resting-state, 134 cognitive, 222 emotional) comprising
5745 BD and 8023 control participants were included. Five
regions survived both significance tests. Individuals with
BD showed functional differences in the right posterior
cingulate cortex during resting-state experiments, the left
amygdala during emotional experiments, including those using
a mixed (positive/negative) valence manipulation, and the
left superior and right inferior parietal lobules during
cognitive experiments, while hyperactivating the left medial
orbitofrontal cortex during cognitive experiments. Across
all experiments, there was convergence in the right caudate
extending to the ventral striatum, surviving only one
significance test.Conclusions: Our findings indicate
reproducible localization of prefrontal, parietal, and
limbic differences distinguishing BD from control
participants that are condition-dependent, despite
heterogeneity, and point towards a framework for identifying
reproducible differences in BD that may guide diagnosis and
treatment.},
