For years the media has misrepresented brain scan studies (“Brain centre for liking cheese discovered!”) but we are now at an interesting point where neuroscientists are starting to seriously look for problems in their own methods of analysis.
In fact, many of these problems have now been corrected, but we still have 100s or 1000s of previous studies that have been based on methods that have now been abandoned.
In part, the piece was inspired by a post on the Neurocritic blog entitled “How Much of the Neuroimaging Literature Should We Discard?” that was prompted by growing concerns among neuroscientists.
The fact is, fMRI is a relatively new science – it just celebrated it’s 20th birthday – and it is still evolving.
I suspect it will be revised and reconsidered many times yet.
