European Starling
I posted a photo of this bird last week. This is a different photo though the pretty much the same pose. The colors are striking, I'd like to get some more photos of these birds sometime.

@seeingwithsound It could be biochemicals... or it could be that re-activated cortical area may cross-talk with other areas. Most brain areas are interconnected, so that's also a possibility. It would be very interesting to see if these things could be tested at a mechanistic level.

I've been listening and reading on AI, and it strikes me how most of the real questions around are far from new, and not technological at all.

So I laughed really hard at this story of a dog who, in 1908, was rewarded with steak for saving a child who'd fallen into the Seine. Naturally, he started pushing kids in to rescue them to get more steak. Much like a bot optimizes to its parameters. (the fancy term is "principal-agent" problem). nytimes.com/1908/02/02/archive

@seeingwithsound Thanks for sharing this interesting story. It's a bit sad that the Argus II implant patients are now on their own.
The mentioned "side-effects" are interesting in terms of neuroscience. I can sort of see how there could be "sharpening" of the residual visual field, which I think may be due to driving feedforward inhibition. But I'm not quite sure what to make of the tingling ear sensation. There was a recent study that suggested that eye movements can cause eardrums to move (pnas.org/doi/10.1073/pnas.1717), but not clear if that'll be related?
Anyway, I do learn a lot from your posts. Thanks :ablobderpyhappy:

Red headed woodpecker.

I took this photo in 2015. We have lots of red bellied woodpeckers visit, but not so many of these guys, they're a little bigger than their red bellied cousins. I didn't see one this year, but I was working a lot.

I'm sure orientation and ocular dominance do not begin to describe what V1 is doing. But they are two important and prominent things that V1 represents, and so a region that gives a complete local representation of them is likely to have a complete local representation of the visual scene.

Goldfinch

I looked through several photos that I had of this bird and think this is the best.

“Caring too much for objects can destroy you. Only—if you care for a thing enough, it takes on a life of its own, doesn’t it? And isn’t the whole point of things—beautiful things—that they connect you to some larger beauty?” - Donna Tartt, The Goldfinch
