Whether the BOLD signal truly correlates well with neural activity is still a matter of contention within the medical community
True, and we should mention that the time resolution on fMRI is on the order of a second or two. This suggests also some significant time walk or smearing in the signal. The point is that minimum brain response time is quite a bit faster than this (a few tens of ms), and this is smaller than the resolution of fMRI.
That being said, if you don't have brain pictures in your grant proposal, your chances of getting a cognitive science grant are greatly diminished. So everyone tries to find some way to use it, whether it makes sense or not.
