The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
those brain networks can be revealed by putting people with PTSD into functional Imaging machines getting them to recall a traumatic event or even looking at the resting state of connectivity between the amygdala and the insula so those experiments have been done
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
a shift from 8 out of 10 to 7 out of ten in another person and to see less shift in brain connectivity in the same network and then perhaps in the person that went from full-blown PT PSD to full remission of PTSD something that believe it or not has been observed in single sessions with MDMA if that person demonstrates an even greater reduction in the connections between the amygdala and the incilla
well then that gives even more confidence that this connection between the amygdala and the insula is actually perhaps causally related to the reduction in symptoms of PTSD or even if it's just correlated with reduction in symptoms of PTSD
there seems to be heightened input from the threat detection centers of the brain to this area of the brain the insula that is responsible for our sense of interception which provides a logical explanation for why people with PTSD often will feel the memory or sense the discomfort or just feel agitation or even other types of bodily Sensations like back pain or just perhaps just a sense within their body that's more generalized it doesn't even have to be pain doesn't even have to be negative but that's associated with the negative memory of some traumatic event or series of events
but I want to emphasize that the modern Neuroscience really points to the fact that PTSD is caused by the exact sorts of brain Network activations that we were discussing earlier things like heightened levels of activation in the amygdala to insulate pathway which of course would exacerbate bodily Sensations related to the trauma or heightened activation of the hippocampus this memory Center in the brain too amygdala to insula circuitry
