Functional neuroimaging studies establish function-location correlations in the human brain using imaging modalities such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). A vast amount of research has been published in this field in the last two decades, involving a wide array of tasks and cognitive or perceptual processes. Recently, quantitative meta-analysis methods have been developed to assimilate results from across these studies, with the ultimate goal of constructing a human functional brain atlas. Multiple meta-analytic strategies and applications will be presented, including a meta-analysis of the Stroop task, a well-known test of response inhibition. In addition, meta-analysis can also be useful in generating models of connectivity across spatially diverse brain regions. As an example, results of a study examining motor connectivity using transcranial magnetic stimulation (TMS) and structural equation modeling (SEM) will be presented.
