Neurosynth is a platform for large-scale, automated synthesis of functional magnetic resonance imaging (fMRI) data.
It takes thousands of published articles reporting the results of fMRI studies, chews on them for a bit, and then spits out images that look like this:
507891 activations reported in 14371 studies
Interactive, downloadable meta-analyses of 1334 terms
Functional connectivity and coactivation maps for over 150,000 brain locations
