1/6 Surrogate gradients (SGs) are empirically successful at training spiking neural networks (SNNs). But why do they work so well, and what is their theoretical basis? In our new preprint led by Julia Gygax, we provide the answers: arxiv.org/abs/2404.14964



Awesome to see two Zebrafish Rock! papers out from my old colleagues UCL Research Dept of Cell & Developmental Biology this week (Anya Suppermpool, The Rihel lab, Stephen Wilson etc): ⚪️ Sleep pressure and synapses (doi.org/10.1038/s41586…) ⚪️ Neuronal asymmetry (doi.org/10.1126/scienc…)

Really enjoyed this thoughtful pair of articles, from Máté Lengyel & Jonathan Pillow, on the usefulness of Marr's three levels in #neuroscience: ❤️doi.org/10.1113/JP2795… ❤️🩹doi.org/10.1113/JP2795…

2 years into making, the last chapter of my PhD thesis, and a set of wonderful collaborators: @m00rcheh, @ShreyDixitAI, Bratislav Misic, @caioseguin, @GZamora_Lopez, Claus C Hilgetag. 🧵 What can we learn about communication in brain networks from 7000 million virtual lesions:



Teaching on the TReND-CaMinA (TReND in Africa) summer school (Rwanda) was an incredible experience. Both the students and staff (below) were super inspiring! Saray Soldado-Magraner, Joana Soldado-Magraner, Tom George, Artemis Koumoundourou, Burak Gür, Tom Chartrand, Po-Chen (Frederic) Kuo, Devon Jarvis etc


Had a great time sharing some new work and meeting everyone UCL_NeuroAI (inactive) yesterday!


I hadn’t really thought about the variety of algorithms that *could* optimally underpin multi-modal processing/integration, until this awesome work by Marcus Ghosh & team. Clear findings w/ experimentally testable predictions on nonlinear fusion in agents & organisms! 👌

How should we support research software engineers? One idea from Rory Byrne!


I will be at #BernsteinConference (Bernstein Network Computational Neuroscience) next week - with my Dan Goodman colleagues. Drop me a message if you'd like to meet up. Otherwise, stop by my poster (IV 47) for some new work on multisensory integration

Really enjoyed presenting at both Universität Konstanz & Bernstein Network Computational Neuroscience recently. And, talking with some great people inc: Pip Coen, Serena Ding, Armin Bahl, Katrin Vogt and may more.
