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.
now we know that they actually require different brain regions. So we don't only have a theory, we don't only have a light environment that showed they can be dissociated. We know that they use completely different brain regions.
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.
So the SCN that I told you about earlier, the place where the central pacemaker is, the one that receives direct input from the retina through the IPRGCS to adjust your circadian clock is not the area that receives the light input for mood regulation. It's a completely different brain region. And what's really amazing, this region also receives direct input from the IPRGC's but projects to areas in the brain that are known to regulate mood including the vententral medial prefrontal preffrontal cortex which has been studied for many years to be impacted in a human depression.
