Our new paper is out today in @NatureNeuro. We investigated how neural activity in physically distant brain regions coordinate during working memory, using human intracranial recordings. (1/5) 🧵👇

How do the basal ganglia turn what you see into what you do?
New preprint w/ @kennethd_harris, @flicker_fusion & Matteo Carandini: we recorded across striatum, GPe & SNr in a Go/No-Go task. Striatum encodes which stimulus, GPe & SNr encode whether to act.

How does the brain process information? We found evidence in favour of a hybrid predictive coding-routing model that combines top-down predictions with superficial-layer inhibition. Models are complementary,not competing-w/ @MillerLabMIT @BastosLabNeuro https://t.co/WbVYIGLvEv

@cyantist Check out Tim Palmer. He proposed that consciousness, free will, creativity, randomness, and quantum mechanics, are inextricably tangled up with each other. I agree with him, and have written up some related ideas in neuroscience. Our theories are on the arXiv. Or just ask!

If you claim to support human rights yet can’t bring yourself to show solidarity with those fighting for their liberty in Iran, you’ve revealed yourself. You don’t give a damn about people being oppressed and brutalised so long as it’s being done by the enemies of your enemies.

[J.K. Rowling @jk_rowling]

If you believe free speech is for you but not your political opponents, you're illiberal.

If no contrary evidence could change your beliefs, you're a fundamentalist.

If you believe the state should punish those with contrary views, you're a totalitarian.

If you believe political opponents should be punished with violence or death, you're a terrorist.

They’re building nuclear plants to power current AI—let alone AGI. Your brain runs on just 20 watts. Clearly, brains work fundamentally differently.

I have a a few friends who are government employees wrapped up in the DOGE "chaos." And unlike what is being reported in the media, they are ecstatic...

Deep down, most (good) people want to feel like their job has meaning and purpose.

They've been spinning their wheels in bureaucracy for years, seeing:
- bosses doing nothing
- complacent colleagues enjoying no-show jobs
- merit and accountability disregarded
- promotions denied in favor of DEI
- corruption and incompetence across the board

It's a breath of fresh air to the good guys... of which, there are quite a few.

This is an absolute rock-bottom moment for the Legacy Media. According to Face the Nation host Margaret Brennan, the Holocaust happened because the genocidal Nazi regime, which defined totalitarianism for the 20th century, allowed too much free speech.

How did we get here? The media is so committed to the narrative that “Trump is Hitler” that anything the administration does must be portrayed as fascist. Hence, if VP Vance gives a speech urging the Europeans to live up their values on free speech, it must now be the case that free speech is a Nazi value. History must be retconned accordingly. Goebbels himself would be impressed by the audacity of this Big Lie!

You can see the hesitation on Brennan’s face and hear it in her voice, as she tries to expound on this chain of thought. She starts to realize the foolishness of her argument, but it’s too late for her to turn back, leading her into an absurd cul-de-sac.

This represent the entire Legacy Media. Their pathological hatred of Trump has led them into a cul-de-sac of absurdity and irrelevance. They have zero credibility left.

In my second book, I wrote about the possibility that the universe might be able to think. You might think I’m joking, or gone off the deep end, or both – but hear me out.

According to multiple new surveys, many people – including scientists – censor personal views. Most worryingly, scientists admit to self-censorship even in academic publications.
