How do brains plan actions towards goals? To get at this question we studied mice navigating complex mazes as goals changed on every trial 🧵 New work with Thomas Akam @behrenstimb @KrisTorpJensen now on BioRxiv: biorxiv.org/content/10.64898…

We’re thrilled to introduce the second cohort of FutureHouse AI-for-Science Independent Postdoctoral Fellows: five exceptional scientists pursuing bold research at the intersection of AI and science. Please join us in welcoming: Hanqing Liu, Alexander Starr, Jeremy Koob, Soojung Yang, and Andrew Lu Starting in September, these Fellows will leverage cutting-edge AI Scientists to advance their projects in genomics, neuroscience, protein design, biophysics, and cancer therapeutics. This year, we're also proud to partner with @KavliFoundation, who is sponsoring one of our Fellows. We’re excited to support this cohort as they pursue ambitious, independent research and help expand what AI can make possible in science. Learn more about the 2026 Fellows and the Fellowship program here: futurehouse.org/fellowship-p… #FutureHouse #AiforScience

New lab paper! 🧠 Human hippocampal & MTL theta activity is linked to eye movements, but only during memory-guided navigation. Theta is also strongest during longer, more exploratory eye movements. plos.io/4dwJhR8 Huge congrats to @humza_n_zubair & team! 👏

Just released a new preprint about how well the parameterized tests of GR can capture generic beyond-GR violations when viewed in the geometry of waveform space (arxiv.org/pdf/2602.17524)

Excited to give a talk at @Winter_QBio this Tuesday, 2/18 during session 1! I’ll be discussing our work using spatial transcriptomics to resolve temporal dynamics in the seminiferous epithelial cycle. Come say hello and chat science!

New results for a new year! “Linking neural population formatting to function” describes our modern take on an old question: how can we understand the contribution of a brain area to behavior? biorxiv.org/content/10.1101/… 🧵1/

A bit late to the party, but I’m very excited to share the first publication from my thesis work at @Caltech ! @Nature nature.com/articles/s41586-0… x.com/UeliRutishauser/status…
Delighted our latest finding! We discovered that abstract representations emerge in the human hippocampus when learning to perform inference. This change in neural geometry is due to disentanglement of discovered latent and observable variables. @Nature nature.com/articles/s41586-0…
