I just read an article that is not satisfying. Not because it is wrong (although…), but because of the findings it discussed.
Memory. As I’ve discussed often, it is a critical component of PTSD (post-traumatic stress disorder). Those episodes where we felt that intense fear can reverberate and then periodically (or continually) revisit our consciousness. In PTSD, it’s the amygdala and the cingulate cortex portions of the brain that are prominent in these recurrences.
