🤖 🧠 🧪 New paper! I'm presenting it TOMORROW at #ALIFE2026! What if a chip could heal itself the way a brain does: not with a spare part, but by rewiring around the wound? Meet Self-Organising Digital Circuits. 👉 self-organising-circuits.github.io/ (go murder some logic gates, I'll explain) 🧵⬇️

Self-Organising Digital Circuits

Extending the Neural Cellular Automata paradigm from pattern formation on grids to functional logic generation and self-repair on arbitrary graphs.

Now published @commsaicomp.nature.com with @neural-reckoning.org We: 🤖 Define a taxonomy of neural network architectures (here 128 unique structures) 🦾 Train > 25,000 models on different navigation tasks #RL 🧠 Link each architecture's behaviour to its memory dynamics doi.org/10.1038/s444...

A taxonomy of recurrence. We defined a family of neural networks for exploring questions in neuroscience and machine learning. Here each network is represented by three circles joined by different connections (short, coloured lines). Networks are joined by longer, pale grey lines if they differ by one connection. Moving from left to right takes us from the simplest to the most complex network.

How does the structure of a neural circuit shape its function? @neuralreckoning.bsky.social & I explore this in our new preprint: doi.org/10.1101/2025... 🤖🧠🧪 🧵1/9

New (and updated) preprint is now out!🔬🧠 We propose a hypothesis regarding how the genome, despite its limited information-carrying capacity, can initialize a brain with billions of neurons that comprise a diverse set of functions. Relevant to: #neuroscience #devleopmental-biology Details 👇

Factorization and spatial encodings: a hypothesis about the foundations of the genomic code

The genomic mechanisms that efficiently encode the initial architecture and synaptic connectivity of neural circuits remain poorly understood. We hypothesise that two primary mechanisms — spatial enco...

If you're in London and want to sit in air conditioning (so I am told) tomorrow afternoon, you can also get a free lecture out of it! Come join me to talk about consciousness, neuroscience, & adversarial collaborations tomorrow afternoon at the Crick! www.eventbrite.co.uk/e/understand...

Understanding the brain in theory and practice

A series of interactive workshops on building better experiment-theory collaborations in neuroscience.

eventbrite.co.uk

Next meeting in this series is this Thursday 4.30pm at Crick institute with Caswell Barry @caswell.bsky.social presenting work on place and grid cells, and how to integrate theory and experiment better. Free registration, free food and free thinking. 😉

How can we build better experiment-theory collaborations in neuroscience? We're hosting a series of 6 in-person, interactive workshops to discuss this. Come along! www.eventbrite.co.uk/e/understand...

If you're in London next Thursday afternoon/evening, come along to our seminar/workshop on how to get theory and experiment working together better in neuroscience. There'll be a short talk by @marcusghosh.bsky.social on "A taxonomy of recurrence" (see below) and a long discussion with free food.

Come do your PhD with me and @ktsetsos.bsky.social ! It's such an exciting time for cognitive and computational neuroscience at @tcddublin.bsky.social . And in this PhD you get to do both!
