Abstract

Activation likelihood estimation (ALE) meta-analyses allow investigators to integrate the results of multiple neuroimaging studies, potentially yielding novel results that may not have been evident in the individual studies. Here, we provide a brief, introductory description of ALE methods for readers without extensive expertise in neuroimaging.

Coloured areas might represent, for example, brain areas that are significantly more activated in individuals with a particular psychiatric disorder relative to comparisons across all studies retained in the meta-analysis.
