      abstract     = {Meta-analytic contrasts are a promising aspect of
                      coordinate-based meta-analyses in neuroimaging research as
                      they facilitate the statistical comparison of two
                      meta-analytic results. They have been used for a multitude
                      of comparisons, such as task conditions, cognitive
                      processes, and groups. However, it remains to be tested how
                      the results of meta-analytic contrasts relate to those of
                      classic meta-analyses and vice versa. Here we present a
                      comprehensive empirical investigation of this issue using
                      four datasets from three different cognitive domains:
                      working memory, working memory load, cognitive interference
                      processing, and emotional face processing. For all four
                      datasets, we compared the results of a standard
                      meta-analysis across prototypical contrasts (condition A >
                      condition B) reported in individual experiments with those
                      of a contrast between two individual meta-analyses of the
                      same conditions (meta-analysis condition A > meta-analysis
                      condition B). In the meta-analytic contrasts similar brain
                      regions as in the standard meta-analysis were found but with
                      relatively distinct spatial activation patterns.
                      Additionally, fewer regions were revealed in the
                      meta-analytic contrasts, especially in areas where the
                      conditions spatially overlapped. This can be ascribed to the
                      loss of information on the strength of activations in
                      meta-analytic contrasts, across which standard meta-analysis
                      summarize. In one dataset, additional regions were found in
                      the meta-analytic contrast, potentially due to task effects.
                      Our results demonstrate that meta-analytic contrasts can
                      yield similar results to standard meta-analyses but are
                      sparser. This confirms the overall validity, but also
                      limited ability to capture all regions found in standard
                      meta-analyses. Notable differences observed in some cases
                      indicate that such contrasts cannot be taken as an easy
                      substitute for classic meta-analyses of experiment-level
                      contrasts, warranting further research into the boundary
                      conditions for agreement.},
