Here are our submissions for Cosyne 2022. Broad theme: Task Abstractions/Coordinate Systems and how to use them. You'll have to come to Lisbon to find out which were accepted.

Oh dear. Look at this ridiculous attempt at summarising all the recent hippocampal state space models. Laughable. (👀James Whittington, mccaffary,Jacob Bakermans) [2202.01682] How to build a cognitive map: insights from models of the hippocampal formation arxiv.org/abs/2202.01682

nature.com/articles/s4158… some ideas summarised, along with Matthew Nour Nico Schuck Tim Behrens & Ray Dolan

I'm pleased to share our Perspective on 'Functional Neuroimaging in Psychiatry', out today in Neuron, with Yunzhe Liu and Ray Dolan, Max Planck UCL Centre for Computational Psychiatry. We reflect on progress and impasses over 3 decades' research. sciencedirect.com/science/articl… cell.com/neuron/fulltex…

This is one of our featured Perspective, freely accessible here: cell.com/neuron/fulltex… A recommended read!

If everything's a big manifold, why do neurons often code for human-interpretable factors? In arxiv.org/abs/2210.01768 we show the most efficient biological representation puts different factors in different neurons. This lets us build machines that disentangle too! 1/9

New pre-print with Peter Latham, Tim Behrens & James Whittington: arxiv.org/abs/2209.15563 We formalise path-integrating representations of space, explain why the optimal representation is multiple modules of grid cells, make testable predictions, and apply to non-2D (1/12)

Excited to share our preprint, with Jo Warren, James Whittington, and Tim Behrens! Hippocampus famously supports memory and scene construction, but recent state-space models have also explained a wealth of hippocampal results. Maybe it does both? biorxiv.org/content/10.110… 1/10

Ever wondered how your brain makes sense of threads like this? So did we! Tim Behrens haim dub and I tried to answer this question in our new paper, now available in Nature Neuroscience. rdcu.be/ddgnK 1/13

Hi all. I presented the brain-modes paper at our group meeting and for this I made a Google Colab to replicate some of it and compare with spherical bases and PCA. Due to popular demand from my lab, I am sharing here. Feel free to play.

With simultaneous EEG-fMRI, we probed human replay in both fine time and space! Amazing work led by Qi Huang Qi Huang et al., along with Ray and Tim Tim Behrens

If you’re at MEG UKI, you can hear Lilian Aline Weber talk about the study tomorrow – and her many cool follow-on studies using MEG with time-varying volatility/stochasticity, EEG+ketamine, and cool new versions of the task that are genuinely clinically tractable with high reliability.

Very happy to share our work providing evidence for distributional reinforcement learning in prefrontal cortex. This suggests it may be a common mechanism for reward-guided learning in the brain. Now out in Nature Neuroscience. 1/n tinyurl.com/2ut5uase

distRL in the primate PFC by the amazing Tim Muller et al.!

what a beautiful historical event of love and trust in science

30 years ago, Wilson & McNaughton (1994, Science Magazine) kickstarted the study of 'offline' hippocampal reactivation, and its role in memory. What a journey it's been since then... Sharing my favorite insights below. #Neuroscience science.org/doi/abs/10.112… 1/13

Temporal structure of experience etched on firing of human hippocampal-entorhinal neurons to serve memory & prediction. See our study nature at UCLA Neurosurgery 🧠, great work by lead author Pawel Tacikowski with Guldamla Kalender & Davide Ciliberti support NINDS. nature.com/articles/s4158…

both beautiful and profound, congrats Mohamady El-Gaby !
