New preprint! Why are long-range connectomic interactions in the cortex dominant in shaping dynamics in some experiments but apparently negligible in others? We (w/ Rishi M, @eli_j_muller) address this by studying a new hybrid model of cortical dynamics. arxiv.org/abs/2506.19800
📜Out in Nat. Commun! We propose a novel framework called “predictive alignment”, which trains the chaotic RNN via a biologically plausible rule. Collaborated with @ClopathLab nature.com/articles/s4146…
🚀Out in PNAS! We find that recurrent networks trained with the predictive plasticity rules explain many features of prediction errors observed in experimental studies pnas.org/doi/10.1073/pn… @ClopathLab
Our preprint is finally out! How can we understand the role of Behavioral Timescale Synaptic Plasticity in credit assignment? Does it fit into existing supervised and unsupervised learning frameworks? What theoretical gaps are still left unexplained? biorxiv.org/content/10.110…
Another paper on embedding stimulus statistics just got published @eLife! "Predictive learning rules generate a cortical-like replay of probabilistic sensory experiences" doi.org/10.7554/eLife.…
Now in @eLife “Biologically plausible excitatory/inhibitory plasticity rules in recurrent spiking networks embed state-transition statistics into spontaneous activity.” doi.org/10.7554/eLife.… @ClopathLab
The @ClopathLab has a fully funded PhD position open for Oct in Computational Neuroscience at Imperial College London. If you are interested, just send us an informal e-mail!
Excited to share our recent work "Flexible gating between subspaces in a neural network model of internally guided task switching", just out on @NatureComms! 🧵👇

Where in the brain is abstract map generated? It is the lateral entorhinal cortex (LEC) and the medial prefrontal cortex (mPFC), working together!! Here is our new finding published in @Nature Prefrontal and lateral entorhinal neurons co-dependently learn item–outcome rules…
Our long awaited feature-specific RPE (previously known as the vector RPE) paper is finally out! 🎇🎇🎇 nature.com/articles/s4159… Huge thanks to co-authors @SagivYotam , @BenEngelhard, @IlanaWitten, @nathanieldaw
