Textbook: tracking position during navigation is primarily the job of the hippocampus. Recent findings suggest a more complicated story. Recording >20k neurons brainwide, we indeed find spatial representations in every region! With @kenneth-harris.bsky.social and @carandinilab.net

1/7 🧠 My journey into development begins with this work and question: how does the brain's spatial navigation system develop? We found that the neural networks for spatial navigation (tori and rings) are preconfigured and only later anchor gradually to the world with experience! 🧵

Latent geometry to describe neural variability with stable decoding! (use case in remapping) With the amazing @billpod.bsky.social Check it out! 🧠

When neurons change, but behavior doesn’t: Excitability changes driving representational drift New preprint of work with Christian Machens: www.biorxiv.org/content/10.1...

Representational drift without synaptic plasticity
Neural computations support stable behavior despite relying on many dynamically changing biological processes. One such process is representational drift (RD), in which neurons' responses change over ...

Our preprint on tracking cells in 2p calcium imaging during development is now online at @elife.bsky.social ! Its cool that the reviews are open - now its revision time 🫡🫡🫡 doi.org/10.7554/eLif...

Made a generic feed/timeline with filters for AI safety, control, alignment and interpretability. Hope a community around this builds here. bsky.app/profile/did:...
