Happy to see my last PhD paper (finally!) out 🥳
Cross-species ferret vs. human, fUSI vs fMRI, round 2!
Is the human cortical hierarchical gradient in background invariance also found in ferrets? Yes!
Are they supported by the same mechanisms? No!

Thrilled to share that our work is now published in Science! ✨
We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭

Two flagship papers from the International Brain Laboratory, now out in @Nature.com:
🧠 Brain-wide map of neural activity during complex behaviour: doi.org/10.1038/s41586-025-09235-0
🧠 Brain-wide representations of prior information in mouse decision-making: doi.org/10.1038/s41586-025-09226-1 +
Promising solution to facilitate or extend the uses of fUSI! 🤩

This looks pretty cool: ultrasound can now see through the skull! 🧠🔊
The skull has long been a barrier to ultrasound. This reprint shows how to make it quickly transparent → enabling full-depth, high-res fUSI in mice (& humans! 🤯🤯)
Huge congrats to the authors!!!

Introducing our new favorite stimulus. A few minutes are enough to map the visual preferences of thousands of neurons.

A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently.
Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries.

Brainwide blood volume reflects opposing neural populations
Brainwide fluctuations in blood volume arise from two populations with opposite relation to brain state and distinct relationships to blood supply
