Another fun eye/brain fact: There are two “outputs” for each eye. One goes to your occipital lobe, in the back, and really processes the image (“That’s a cup, it <holds liquid> <is firm with a medium weight>…” etc) and one goes to your brain stem, which processes movement.
It’s possible to have the connection to the occipital lob severed, but not to the brain stem. It’s a condition called blindsight. The result is that if you showed someone a cup, they wouldn’t be “see” it; they wouldn’t know what it is and wouldn’t register you were showing them anything at all… but if you tossed it to them they could catch it.
I met a person long ago that had one hemisphere “dead” after several strokes. So their vision was cut in half in a way I couldn’t really understand before I found out about this.
So they could just see one side (left maybe) but with both eyes, like if you took a screenshot of a FPS view and completely cut off one half of the image
I literally just finished having a migraine aura (it’s only the second time I’ve had one, though no headache the first time and no headache yet now.) I was reading a bit about it and how it’s a caused by a slow wave going across one’s brain. It started in the middle of my vision on the drive home, and after I arrived it continued sweeping off to my left field of vision until it dissipated off into the periphery a few minutes ago.
It’s interesting to look at this image and imagine the wave going across the back of my right brain hemisphere. It’s also interesting how even the visual looked like the cone-shaped wave that follows a sonic boom, slowly spreading out.
And now, with such dire imagery and the potential for upcoming pain, I’m going to lie down and hope nothing else happens.
Wish you a speedy post-drome. I had migraines for a year in the past, and the thought of going through that again fills me with dread.
That explains why one of my eyes turns off when I do loads of ket.
this you?
One eye per hemisphere? Are you that one Hollywood exec who insists humans only use 1% of their brain?
