cells activated by naturally recalling the unpleasant memory The maps highlighted many regions expected to participate in memory, but also many that were not This feels like a study from decades ago, as if it were done in complete ignorance of the fact brains store event descriptors and entity descriptors separately. "Program data" and "character data" to use an analogy. Of course that sort of unselective "memory make marker go brr" analysis will show up all over the place because the brain is touching a dozen or more different types of data at once. If you want usefully specific results you have to use usefully specific methods.
