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.
Normally in a person without ADHD, the task networks and the default mode networks are going in kind of Seesaw fashion, they are actually what we call anti-correlated. So it's not just that they are not correlated, they're actually opposing one another they are anti-correlated.
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.
when somebody gets better, when they're treated for ADHD or when they age out of ADHD, as sometimes it's the case that the default mode networks and the task networks tend to become anti-correlated again, okay?
In a person with ADHD, the default mode networks and the tasks networks are actually more coordinated. That might come a surprising, I think that we all have this tendency to kind of jump to conclusion and assume that somebody who doesn't have an easy time paying attention or has ADHD, that their brain must be completely incoherent that it's not working well and because everything's out of whack, but there's something interesting about people with ADHD whereby the task networks and the default mode networks are actually working together in a way that's correlated and that is what's abnormal.
