abstract = {Posttraumatic stress disorder (PTSD) has a well-defined set
of symptoms that can be elicited during traumatic imagery
tasks. For this reason, trauma imagery tasks are often
employed in functional neuroimaging studies. Here,
coordinate-based meta-analysis (CBM) was used to pool eight
studies applying traumatic imagery tasks to identify sites
of task-induced activation in 170 PTSD patients and 104
healthy controls. In this way, right anterior cingulate
(ACC), right posterior cingulate (PCC), and left precuneus
(Pcun) were identified as regions uniquely active in PTSD
patients relative to healthy controls. To further
characterize these regions, their normal interactions, and
their typical functional roles, meta-analytic connectivity
modeling (MACM) with behavioral filtering was applied. MACM
indicated that the PCC and Pcun regions were frequently
co-active and associated with processing of cognitive
information, particularly in explicit memory tasks.
Emotional processing was particularly associated with
co-activity of the ACC and PCC, as mediated by the thalamus.
By narrowing the regions of interest to those commonly
active across multiple studies (using CBM) and developing a
priori hypotheses about directed probabilistic dependencies
amongst these regions, this proposed model-when applied in
the context of graphical and causal modeling-should improve
model fit and thereby increase statistical power for
detecting differences between subject groups and between
treatments in neuroimaging studies of PTSD. Hum Brain Mapp,
