The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
The increase in epinephrine that occurs just afterward is what's going to consolidate the information. It's going to ensure that the proper circuits and mechanisms in the brain for neuroplasticity are engaged during sleep later that night or the next night which is when the real rewiring occurs.
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.

It's correlating neural chemical states of the brain and body, different patterns of electrical activity in the brain. This is important because it really emphasizes the fact that both negative and positive emotional states and the different but somewhat overlapping chemical states that they create, or the conditions, as we say the and gates through which memory is laid down. An and gate is simply a condition in which you need one thing and another to happen in order for a third thing to happen. So you need epinephrine elevated and you need robust activity in a particular brain circuit if in fact that brain circuit is going to be strengthened. It's not sufficient to have one or the other, you need both. Hence, the name and gate. And the amygdala is very good at establishing these and gate contingencies.
