                      hyperalgesia processes have been widely investigated with
                      neuroimaging methods. However, few studies have directly
                      compared these two processes and it remains unclear whether
                      common or distinct neural circuits are involved. To address
                      this issue, we implemented a coordinate-based meta-analysis
                      and compared neural representations of placebo analgesia (30
                      studies; 205 foci; 677 subjects) and nocebo hyperalgesia (22
                      studies; 301 foci; 401 subjects). Contrast analyses
                      confirmed placebo-specific concordance in the right ventral
                      striatum, and nocebo-specific concordance in the dorsal
                      anterior cingulate cortex (dACC), left posterior insula and
                      left parietal operculum during combined pain anticipation
                      and administration stages. Importantly, no overlapping
                      regions were found for these two processes in conjunction
                      analyses, even when the threshold was low. Meta-analytic
                      connectivity modeling (MACM) and resting-state functional
                      connectivity (RSFC) analyses on key regions further
                      confirmed the distinct brain networks underlying placebo
                      analgesia and nocebo hyperalgesia. Together, these findings
                      indicate that the placebo analgesia and nocebo hyperalgesia
                      processes involve distinct neural circuits, which supports
                      the view that the two phenomena may operate via different
                      neuropsychological processes.Keywords: Activation likelihood
