I've always found the comparisons between "amateur" and a "professional" interesting [1], where professionals show spatially tighter activity and overall lower activity. So, it sometimes largely imaging areas where optimization hasn't happened yet. Seems like there would still be some use in looking at what's physically there. And, knowing that all humans have roughly the same activity patterns seems very important, in the sense that we're not some blank slate for concepts to be encoded.
