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.

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

Need to dig in to this paper more, but boy does this recent work from the Froemke lab make me excited:
https://www.nature.com/articles/s41586-022-05554-8?WT.ec_id=NATURE-20230112
Understanding how neural interfaces engage plasticity in the brain will be game-changing for improving therapies.

Our society has reached a tipping point with #AI. The harm is skyrocketing, and the claimed benefits are mostly snake oil.
In this blog post, I describe the real-world harm being caused by four different AI systems, all working in gray areas of the law. In the latest development, Microsoft is using voices from public-domain audiobooks for a synthesis system that seems built for deepfake porn and political repression.

I've been an academic for over a decade and I still cannot convince my family that:
- Yes, I do actually work on non-teaching days; and
- Yes, my articles really DO take that long to write

I increasingly think that “freedom” is the most important word to take back from the fascists.
In rightwing hands, freedom often means
“no rules to allow billionaires to accumulate all the profits and power” or “privatize and destroy societal services” — schools to healthcare.
Real freedom is freedom from want, freedom to pursue happiness without worry about healthcare bankruptcy and with good schools for all.
