🔎👀 for a postdoc position…
- 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!!!
- 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🧵
- All details, links, code etc. can be found here: tomge.org/papers/simpl/ And a huge shout out to my amazing collaborators Pierre Glaser as well as @clopathlab.bsky.social, Kim Stachenfeld and @caswell.bsky.social ! 2/21
- TL;DR 1. Start by assuming the latent IS behaviour (e.g. the animals position) … 2. ...fit tuning curves to this latent… 3. …re-decode the latent from these tuning curves… 4. …repeat steps 2 and 3 You will, very quickly, converge on the “true” latent space.

View full threadAt the risk of rambling I'll end the thread here and perhaps do a deeper dive in the future. Give it a read (or better, try it on your data) and let us know your thoughts! tomge.org/papers/simpl/ 21/21
- 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!)
