It was again a great pleasure to collaborate with team! Check out our most recent work! 🤔how does brain 🧠 solve time and space in generalization task!
Excited to share our latest story! We found disentangled memory representations in the hippocampus that generalized across time and environments, despite the seemingly random drift and remapping of single cells. This code enabled the transfer of prior knowledge to solve new tasks
Redundancy and high dimensionality are overlooked in robotics. They are crucial aspects to building a "complex" system, instead of just a "complicated" system. What you get is speed, smoothness, robustness, and performance.
Can an AI model predict perfectly and still have a terrible world model? What would that even mean? Our new ICML paper formalizes these questions One result tells the story: A transformer trained on 10M solar systems nails planetary orbits. But it botches gravitational laws 🧵
'Night science' is what you do when you're not sure what's the question.
Our new paper is out in Science. We identified a subgroup of cholinergic neurons that mediate sensory modality-specific attention. They change their funcitonal properties within secs of behavioral context change. Congrats to Bin and the team! science.org/doi/10.1126/sc…
#PR Our study on sleep & learning is out in PLOS Biology! We show how synaptic connections may strengthen during sleep, called WISE: Wake Inhibition Sleep Excitation. Congrats Fukuaki! Experimental proof will follow in the future. Recruiting grads! Ms→journals.plos.org/plosbiology/ar…
Happy to share my first post-doc paper with Peter Dayan just published at @NeuroCellPress "Multistability, Perceptual Value, and Internal Foraging" Paper (free access before Oct 18th): authors.elsevier.com/a/1ffq33BtfH1Y… No access? Email me at [email protected] 🧵👇
Thank you Antonio Fernandez Ruiz, PhD (@antferrui) and Robert Hill, PhD (@bobalhill) for presenting their research at the recent Klingenstein Fellowship Awards in Neuroscience Conference. 📷 : @SimonProPhoto1

I’m incredibly honored to receive the 2025 @WeintraubAward! I’m extremely grateful for my advisor, PI, and friend @jesseGlab for his unwavering support and all members of the Goldberg Lab, as well as everyone at @CornellNBB! A huge congrats to my fellow recipients!
A huge congratulations to the recipients of the 2025 Weintraub Award! These ten exceptional graduate students exemplify the bold, creative, and pioneering spirit embodied by Dr. Hal Weintraub. fredhutch.org/en/news/releas…
Don’t miss this amazing work on long-term hippocampal population dynamics underlying the development of cognitive maps. So happy to have @sunw37 as a neighbour !
1/12 How do animals build an internal map of the world? In our new paper, we tracked thousands of neurons in mouse CA1 over days/weeks as they learned a VR navigation task. @nspruston @HHMIJanelia, w/ co-1st author @JohanWinn Video summary: youtube.com/watch?v=yw_4uV… Paper:…

Glad to share my first paper in postdoc! This was a huge undertaking by many people over the years: @SetayeshRadkani Neelima Valluru @neuromochi @mjaz_jazlab I hope you read it! But the short version is this: ACC integrates evidence from self experience and observed experience...

First paper from my PhD is out! 👀arxiv.org/abs/2502.08009 Together with @s_y_chung and @kchonyc we show that different prompting methods (like in-context learning with demonstrations, abstract task instructions and prompt tuning) have distinct effects on the geometry of internal…
Brain circuits, gene networks, social media - they all share the same underlying pattern of connections called small-world graphs, which optimally balance local clustering with global integration 🧠 In the new video we talk about what small-worldness is and how it gives the…
#拡散希望 東大医の佐藤さんの論文がiScienceに掲載。佐藤さんおめでとう。頑強な睡眠時徐波の機構の理論研究です。最近ラボ内でCa2+以外にNa+やK+中心の機構が理論上可能と判明し、本論文はNa+を詳述。今後の実験での解明に期待 原著は→ sciencedirect.com/science/articl… PRは→ u-tokyo.ac.jp/content/400255…
Happy 2/11 - International Day of Women and Girls in Science!!
The world needs science, and science needs women. 👩🔬🧪 Yet, they remain under-represented and struggle to get recognition for their achievements. More from @UNESCO on Tuesday’s International Day of Women & Girls in Science: on.unesco.org/WomenInScience
