This is an important one. That soma-targeting interneurons can do background subtraction and gain modulation is well understood. But the roles of dendrite-targeting interneurons in normalizing top-down learning signals have not been studied in detail.

Really stoked to see this project in (pre)print. On how to implement normalization-via-inhibition in ANNs, and what it might mean for inhibition in the brain. ⚖️ Great job @royeyono.bsky.social and the team 👏👏👏

Here's a lovely #blueprint on a new study from our lab led by @royeyono.bsky.social. tl;dr: it implies that there may be interneurons whose role is to normalize credit assignment signals during learning. #neuroscience 🧪

How do neural circuits in the brain implement normalization? 🧠 In our new paper, we show that just normalizing sensory input isn't enough. Crucially, we must also normalize the error signals! 🧵👇 Paper: arxiv.org/abs/2603.17676

Inhibitory normalization of error signals improves learning in neural circuits

Normalization is a critical operation in neural circuits. In the brain, there is evidence that normalization is implemented via inhibitory interneurons and allows neural populations to adjust to chang...

Thrilled to announce I'll be starting my own neuro-theory lab, as an Assistant Professor at @yaleneuro.bsky.social @wutsaiyale.bsky.social this Fall! My group will study offline learning in the sleeping brain: how neural activity self-organizes during sleep and the computations it performs. 🧵

Apropos of never ending discussions about whether ANNs are "good" models of the nervous system, here is a slide I present to masters students showing a network that is found in motor control circuits *across phyla* (that's pretty ubiquitous!) I ask them to guess what it does...

1/ Okay, one thing that has been revealed to me from the replies to this is that many people don't know (or refuse to recognize) the following fact: The unts in ANN are actually not a terrible approximation of how real neurons work! A tiny 🧵. 🧠📈 #NeuroAI #MLSky

Why does anyone have any issue with this? I've seen people suggesting it's problematic, that neuroscientists won't like it, and so on. But, I literally don't see why this is problematic...

OK If we are moving to Bluesky I am rescuing my favourite ever twitter thread (Jan 2019). The renamed: Bluesky-sized history of neuroscience (biased by my interests)

Delighted to be in Leeds joining the School of Computing! Fantastic first impressions — like a "less offensive London" (youtu.be/watch?v=_6_VVLgrgFI). Stay tuned for a PhD position starting next October. Meanwhile, drop me a message with your CV and research interests—I'd love to hear from you!

Pleased to welcome @repromancer.bsky.social - a computational neuroscientist - to the @universityofleeds.bsky.social today - working on the boundary of neuroscience and AI. Welcome Jonathan!

1. Hi all: I’m here to advertise our new preprint: www.biorxiv.org/content/10.1..., with Fabrice Normandin, @tyrellturing.bsky.social, and @glajoie.bsky.social!

The oneirogen hypothesis: modeling the hallucinatory effects of classical psychedelics in terms of replay-dependent plasticity mechanisms

Classical psychedelics induce complex visual hallucinations in humans, generating percepts that are coherent at a low level, but which have surreal, dream-like qualities at a high level. While there a...

I have admired Thomas Sankara for as long as I can remember. In this blog, I put myself in his shoes and imagine what he would have thought of this new age of AI. Thought this would be fitting as my inaugural post on BlueSky!
