The movie reconstruction from brain activity work was from my lab, thanks for the shout out!

The problem with many methods of analyzing and modeling functional MRI data is that the signal-to-noise varies hugely across time, across individuals and across brain regions within an individual. Unfortunately, the most common methods of analyzing and modeling fMRI data do not incorporate any principled method for dealing with this SNR variability.

What makes this frustrating from a practitioner's point of view is that we do have methods for analyzing and modeling these data that can account for these uncontrolled SNR changes. The problem is that most people don't use these methods. (My lab has pioneered many of these techniques, and that is why we could produce those compelling decoding results.)
