Functional Magnetic Resonance Imaging Data Analysis: State of Affairs and Challenges
Functional Magnetic Resonance Imagingcan be easily applied anywhere in the world, given the ubiquitous availability of MRI instruments that can run echo-planar imaging sequences, the hallmark of
fMRI. Second, software packages have been developed (e.g., SPM, FSL, AFNI, BrainVoyager) that allow for a cookbook-type analysis of the data without requiring a solid understanding by the investigator of what exactly is being done. Third, there has been a lamentable growing trend among scientific journals to downplay the Methods section of a paper in general, and the detailed explication of statistical analyses in particular, as evidenced by: the pushing of the Methods section to the end of the paper; frequently publishing it in small print; or eliminating it altogether from the main text and allocating it to "Supplementary Material" (Georgopoulos and Karageorgiou 2008).
