When neurons change, but behavior doesn’t: Excitability changes driving representational drift New preprint of work with Christian Machens: www.biorxiv.org/content/10.1...

Top-down feedback is ubiquitous in the brain and computationally distinct, but rarely modeled in deep neural networks. What happens when a DNN has biologically-inspired top-down feedback? 🧠📈 Our new paper explores this: elifesciences.org/reviewed-pre...

Just a couple days until Cosyne - stop by [3-083] this Saturday and say hi! @nandahkrishna.bsky.social

Hi BlueSky fam, for my first post and to celebrate our recent paper being physically published I thought I’d do a summary thread! This has been my most favourite (and toughest) work to date. Please help share around!! www.cell.com/cell/abstrac... (Reach out if you can’t access)

How do interneurons reshape neural responses? I'm excited to present work with @eerosim.bsky.social at #NeurIPS2024 that proposes a nonlinear recurrent circuit model motivated by efficient coding theory. Poster: 4:30p on Fri, Dec 13 Paper: openreview.net/forum?id=ojL...

Why does #compneuro need new learning methods? ANN models are usually trained with Gradient Descent (GD), which violates biological realities like Dale’s law and log-normal weights. Here we describe a superior learning algorithm for comp neuro: Exponentiated Gradients (EG)! 1/12 #neuroscience 🧪

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!
