FMRI (functional Magnetic Resonance Imaging) is an increasingly popular imaging technique used to understand brain functionality. Scans of the subject's head are taken at regular intervals as the subject performs some mental task resulting in hundreds of 3D datasets. Large databases containing thousands of fMRI scans are already accessible to the research community: the Brain Image Database (BRAID), the fMRI Data Center (fMRIDC), etc.
