I love how this illustration makes clear that the eyes (neural retinas at back of the eyes to be specific) are part of the brain/CNS.

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.

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.
Your eyes are extruded out from the rest of your brain during development.
If ever there was doubt that our eyes (retinas to be exact) are pieces of brain extruded from the rest to eventually reside outside the cranial vault, see this video.
So, you said there's contradictory activity, looking up is controlled by the one set of cranial nerves. And then the closing of the eyelids, is controlled by another cranial nerve.
the retina, including your photoreceptors, are not just connected to your brain. They're not just near your brain. They are actual central nervous system tissue. They are the only two pieces of your brain, meaning your neuroretinas are the only two pieces of your brain that reside outside your skull, or at least outside the cranial vault.
they are two bits of brain your retina is central nervous system
