Making big data open: data sharing in neuroimaging

Nat Neurosci. 2014 Nov;17(11):1510-7. doi: 10.1038/nn.3818. Epub 2014 Oct 28.


In the last decade, major advances have been made in the availability of shared neuroimaging data, such that there are more than 8,000 shared MRI (magnetic resonance imaging) data sets available online. Here we outline the state of data sharing for task-based functional MRI (fMRI) data, with a focus on various forms of data and their relative utility for subsequent analyses. We also discuss challenges to the future success of data sharing and highlight the ethical argument that data sharing may be necessary to maximize the contribution of human subjects.
