Maintained by Dartmouth College, the fMRI Data Center serves as a repository for the functional magnetic resonance imaging data for peer-reviewed, published studies. Intended to help the fMRI research community "speed the progress and the understanding of cognitive processes and the neural substrates that underlie them," the fMRI Data Center is in the process of making all datasets and associated material completely Web-accessible. Currently, the datasets (36 total, with more added every year) are available as free CDs, which the fMRI Data Center will ship directly to interested users. The fMRI Data Center enthusiastically urges researchers to submit peer-reviewed articles and underlying datasets, and may eventually accept any pertinent data.
