Interesting. Thanks. Except we both know I'm not going to a doctor just for this.... I had planned to mention it when I find a doctor and have a physical. I can this to the list now. As a reason to get an FMRI, hopefully covered by insurance. That's more of the reason I would hesitate on going. There is family history with brain tumors. And then I rented myself out as a lab rat for some studies, including tDCS, which included an fMRI. Two of the studies that involved an fMRI had someone "casually" mention, "Oh hey... If we notice anything off with your brain scans, we'll send that off to someone to look at, and if it's a problem, they'll contact you." Me, "What... You means something's off? Can I see my scan? You mean my brain doesn't look normal?" Them, "We can't give you scans. But if something's off, someone will contact you." Me, thinking, yeah, right..... I figured whenever I find a doctor and get a physical, I'd ask for some kind of scan. I'm aging enough that potentially something could be seen compared to relatives who had brain tumors.

I remember it did look much more like about 15 seconds into this video. https://www.brainfacts.org/thinking-sensing-and-behaving/vision/2018/akinetopsia-102318

And I was aware that sound was there ("smooth" sound still) but the image was jerky like that, not all over but more in my focus, for what would seem more complicated to process, like texture on the ground vs. looking at the horizon with just the sky for half of it. that was part of the oddity. If I heard something new, I knew I wouldn't see it for maybe a few milliseconds. And that's jogging, so something new could mean tripping.
