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!!!

Our didactic review on machine learning for causal inference, now open access:
• identifiability (theory of when the data can answer a causal question)
• machine-learning estimators
• study design (asking well-framed questions + loopholes, eg with timewise data)

Thanks to @physmedparis.bsky.social @iconeus.bsky.social @mickaeltanter.bsky.social and Sophie Pezet as well as all my other incredible co-authors!

We tackle energy consumption modeling for path integration using fUSI data and, finally, fUS minute-scale oscillations vs. minute-scale behavior.

Other behavioral correlates do appear, but not as striking as animal speed.

Metrics for decoding continuous locomotion speed with fUSI data match decoding results using standard ephys methods (for speed cells or theta freq, for example).

We show that robust spatiotemporal correlation patterns appear when comparing relative cerebral blood volume with continuous animal speed. These patterns start from dorso-thalamic nuclei than go to parahippocampal regions (MEC, PaS, PrS…) to finally peak in the hippocampus proper (CA1, CA3).

🚨 Preprint alert 🚨
The main results of my PhD are online and I only now could find some time to post about it!

We explored the neurovascular activations of spatial navigation by using functional ultrasound imaging (fUSI) in freely moving rats during open field.

We need your help!!! 🧠🧪💤

If you are human, you fall asleep at least once a day! What happens in your mind then?

Scientists know actually very little about this private moment.

We propose a 20-min survey to get as much data as possible!

Enormous amount of work put into it by @sdiebolt.bsky.social! Glad to be part of it :)

🚨 New preprint alert!

We benchmarked 792 denoising pipelines for #fUSI in awake mice 🐭🧠

Our results show how they reduce motion artifacts and impact seed-based connectivity analyses.

Illustration done for the first publication of my colleague Nicolas Zucker. He managed to measure heart and breathing rate by monitoring tissue motion in the brain using ultrasound, what a crazy idea ! #sciart 🐡 #scicomm 🧪 #neuroscience 🧠🫀🫁🤯

Hey fUSI users. As you were well aware, the next meeting on fUSI-BIDS, our soon to be data sharing standard, is happening next week 12/02 4pm CET. Please join us (details in the doc docs.google.com/document/d/1...) to discuss bidsification, metadata and share your opinion before your data 😉

Join us at fUSbrain #DAYS, a workshop on ultrasound neuroimaging, in 19-20/06/2025 in Paris. Submit your abstract on www.physicsformedicine.espci.fr/fusbrain2025
Organized by PhysMedParis, with the support of Iconeus.

Our preprint of my PhD’s work in @gisellavetere.bsky.social lab is finally out on BiorXiv: doi.org/10.1101/2024..., and I’m so excited to share it! If you’ve ever wondered about reconciling engram manipulation experiments and neuronal activity during encoding, you’re on the right thread! 1/14
