This is a great platform of published fmri data. There are up to 9721 studies in this platform. SO, if you are interested in knowing who else found activation in a specific brain area, what type of design was used and the scanning parameters just go to neurosynth.org
Before, be aware of the type of template you have used to normalize your functional data.
Enjoy!
