1/ Check out our new modeling paper on predictive learning in the hippocampus! 🧠 www.biorxiv.org/content/10.6... A central idea in neuroscience is that the brain makes sense of the world by learning to predict its environment 🧠➡️🌍.

A little overdue but happy to announce that I 1) Got my PhD 🎓 2) Started a postdoc and CNS fellowship with Blake Richards and Guillaume Lajoie (@glajoie.bsky.social @tyrellturing.bsky.social) Come find me out in @Mila_Quebec, Montreal working on new things neuroAI!

Deadline extended until 31st January!!!

Join us in Zambia for the third TReND-CaMinA course: computational neuroscience & machine learning in Africa. 📆Applications open until 15.01. 🧠🧪 trendinafrica.org/trend-camina/

Very nice work by @sjshipley.bsky.social on place cells and Alzheimers!

Excited to share that our preprint is out! doi.org/10.1101/2024... The structure of place cell reactivations was disordered in AD mice compared to WT! This was predictive of reduced place cell stability and memory performance on a radial-arm maze task. Here are a few details: 1/5🧵

What are the brain’s “real” tuning curves? Our new preprint "SIMPL: Scalable and hassle-free optimisation of neural representations from behaviour” argues that existing techniques for latent variable discovery are lacking. We suggest a much simpl-er way to do things. 1/21🧵

Epic data and representational analysis work by @jquinnlee.bsky.social on CA1, now out in Neuron! Highly recommend people taking a look (+ amazing visuals, these flow diagrams are fascinating to look at!)

Quinn Lee@jquinnlee.bsky.social · 2y ago

When we looked more closely at why this type of model did so well, we found it is because it predicts how the CA1 spatial code moves when you change geometry of the space.

Psyched that my postdoc work w @markbrandonlab.bsky.social + @atkeinath.bsky.social is now in Neuron! TL/DR: remapping in CA1 has a representational structure that is reliable across brains, and we use this representation to test models of cognitive maps. #NeuroSky #NeuroAI 🧪🧠 tinyurl.com/4juhmad8

Identifying representational structure in CA1 to benchmark theoretical models of cognitive mapping

Decades of theoretical and empirical work have suggested the hippocampus instantiates some form of a cognitive map. Yet, tests of competing theories h…
