1/ Excited to share our recent work in #ICML2025, “A multi-region brain model to elucidate the role of hippocampus in spatially embedded decision-making”. 🎉 🔗 minzsiure.github.io/multiregion-br… Joint w/ @FieteGroup @jaedong_hwang, @brody_lab, @PrincetonNeuro ⬇️ 🧵 for key takeaways…

Is that a B or a 13 in the middle? 🤯 A classic case of top-down signals shaping bottom-up perception. ✨Excited to share our work at #NeurIPS2024 w/ @abhiramiyer (*co-first*), Valmiki Kothare, & @FieteGroup: a framework to study context-driven sensory processing. ✨ (1/n)

🧠 A story about the brain, told through self-supervised learning: Grid cells, known for mapping physical spaces, also appear to track *abstract spaces* like ideas and sounds. How? 🤔 Excited to share the first of 2 papers at #NeurIPS2024! With @SarthakChandra @FieteGroup. 1/n

1/5 Very excited to announce our new paper that formally defines compositionality, giving us theoretical insight into what it actually is and helping us build it into AI models. This was work with @tomjiralerspong, @Yoshua_Bengio, and @g_lajoie_. arxiv.org/abs/2410.14817…

JOB ALERT: Computational Cognitive Neuroscience Postdoc position in Osaka, Japan! Possible start in October 2025 (contact me ASAP), or from April 2026. PLEASE REPOST! 1/

We have one poster in this afternoon's session at #ICML2025 (West Exhibition Hall B2-B3, W-414). Unfortunately, none of the authors could attend the conference, but feel free to contact me or @EvaYiXie if you have any questions! icml.cc/virtual/2025/p…

1/ Our paper appeared in @Nature today! nature.com/articles/s4158… @FieteGroup @KhonaMikail. Explains emergence of multiple grid cell modules, w/ excellent match to data! Novel mechanism for applying across vast systems from development to ecosystems. 🧵👇

1/ Super-excited to share our new work “Episodic and associative memory from spatial scaffolds in the hippocampus”, out in Nature today! nature.com/articles/s4158… @FieteGroup @sugsharma @rischaudhuri. Key insights and ideas 👇#tweeprint

New paper out in @NeuronCellPress: A general theory of sequential working memory in prefrontal cortex and RNN/SSMs with their exact neural mechanism. Plus unifying this new mechanism with the alternate mechanism of hippocampal cognitive maps! (1/9) cell.com/neuron/fulltex…

My 2nd to last #neuroscience paper will appear @unireps !! 🧠🧠 Maximizing Neural Regression Scores May Not Identify Good Models of the Brain 🧠🧠 w/ @KhonaMikail @neurostrow @BrandoHablando @sanmikoyejo Answering a puzzle 2 years in the making openreview.net/forum?id=vbtj0… 1/12

This is today :)) #CCN2024
