1/2 🎇 Good news! 🎇 The kind people at Behavioral and Brain Science have made the new collection on "Conscious AI and biological naturalism" #OpenAccess for a limited time: target article, all 50 commentaries, & my response. Go to the link and click 'save pdf': doi.org/10.1017/S014.... Do share!

Behavioral work is not that demanding. The main difficulty, I would say, is that the little critters never do what you want. Which is kind of the point, I guess. Actually there's still much computational work to do on video analysis (not currently solved by AI).

Well for one, I'm pretty sure OpenAI doesn't care. Plus, even a theoretician can do experiments!

If you want to move to unicellular neuroscience I will help :)

Le cerveau est un organe à la fois fascinant et complexe. Il n’est pas toujours aisé de comprendre son fonctionnement. Alors... on se laisse happer par des explications séduisantes et intuitives qui sont en réalité fausses - ce sont les neuromythes. Sommes-nous accros aux mythes sur le cerveau ? 🧠

Neuro arnaque sort aujourd'hui chez Textuel.

On nous explique les crise écologiques par le striatum, l'inégalité scolaire par les gènes, les préférences genrées par l'évolution... La neurobiologie réelle raconte une tout autre histoire.

Avant la manif, pensez à écrire à vos député·es. On a 48h pour les alerter - au moment de l'examen du Projet de Loi de Finances. J'ai écrit et envoyé ça:

Mail type pour alerter les députés du délabrement des universités et des conditions d'études déplorables offertes aux jeunes

One reason (among many) to study protists: as a toolbox, nature is unbeatable

In that post, I pointed out that an LLM does not understand language because LLMs are trained on form, not meaning. There's a paper by @emilymbender.bsky.social and @akoller.bsky.social that makes this point in detail. From 2020, but still accurate.

Ah ben non dotation c'est un financement récurrent, non sujet à appel d'offre. Et bourse c'est pour des financements individuels. Financement de projet, ou à la limite subvention.

Les titres sont faits par ChatGPT, ou bien c'est juste un titre scandaleux?

I think there are two key lessons from Linguistics as we deal with LLMs/chatbots being imposed on us everywhere. Grateful for Undark Magazine giving space for me to lay these out:

++ Linking the unity of consciousness to the unity of metabolism

Also, @anilseth.bsky.social makes an error by relating thermodynamic free energy to informational free energy (not a physical quantity). An organism imports (not minimizes) free energy in order to survive. The opposite basically.

Let's celebrate the "beauty of microscopy" with fake microscopy images! Yay!

We are looking forward to tomorrow, on September 23rd, 2026 at 10h30 for the presentation of the book The Brain in Theory and the Q&A with Romain Brette at the Institute Pasteur. Here it's the link to follow the event online and be part of the Q&A. www.crowdcast.io/c/brain-in-t...

Isn't it 10:30am?

We think this is exciting because foraging is a complex ecologically relevant behavior potentially involving sensory processing, memory, decision making, and motor control, and now we can study this in a unicellular organism!
