Caution to fMRI researchers: "Remember the Dead Salmon"

As a caution to their fellow researchers reporting ever more optimistic interpretations based on fMRI studies comes this research.

A dead salmon was placed in a fMRI machine and shown "a series of photographs depicting human individuals in social situations."  By appropriately setting the detection thresholds on subsequent voxel analysis, the investigators could generate results showing correlated brain activity in the dead fish when "viewing" images. 

Their recommendations?  Don't be fooled by false positives in your research data -- Like their test subject, it could start to smell later.
