There’s a lot of junk fMRI research out there. Here’s what top neuroscientists want you to know.

If you’ve followed the latest from the world of neuroscience, you might get the impression that the field is in deep trouble. In July, a report in the Proceedings of the National Academy of Sciences declared that as many as 40,000 papers using the standard tool in neuroscience research, functional magnetic resonance imaging (fMRI), could suffer from a statistical flaw that rendered their results to be a false positive. Headlines feared the worst: These studies aren’t necessarily wrong, per se. It’s that the common statistical software they used is prone to wrongly guess the borders of “lit up” areas in the brain. But authors of the PNAS paper quickly realized their estimate of 40,000 papers was too high. (The actual number of papers implicated is probably closer to 3,500, one…
