🚨 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. Check it out on @biorxivpreprint 👇 🔗 biorxiv.org/content/10.110…

1/8. New preprint! Using fUSi in head-fixed mice🐭, we found that arousal events trigger a brain-wide wave of activity 🌊🧠. Surprisingly, this pattern was preserved during manipulations of the locus coeruleus, pointing to a minor role for noradrenaline. biorxiv.org/content/10.648…

Next #fUSI - #BIDS meeting coming up! 🧠 📅 March 19, 5PM CET 🎯 Solving remaining spec remarks & moving toward official maintenance. Newcomers welcome! 🚀 Planning to BIDSify your data? Join us, we’re here to answer your questions. Details on the GDoc: docs.google.com/document/d/1W3…

fMRI signals “up,” but neural metabolism might be going “down.” In our @NatureNeuro paper, we show that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funding @ERC_Research 🧵:

Long-awaited #fUSI - #BIDS meeting scheduled! 🧠 📅 Nov 27, 5PM Paris time 🎯 Finalizing BEP for BIDS maintainer discussions Implemented fUSI-BIDS or planning to? We need your input to strengthen the spec. Join us! Details on the specification GDoc (docs.google.com/document/d/1W3…)

#STROKE: Multimodal imaging (fUS + MRI) in fully awake mice reveals hyperacute stroke dynamics and connectivity changes, enhancing translational relevance. @AmaBonnet @LesageFabreLab @SamuelDiebolt @TanterM @Inserm @PhysMedParis ahajrnls.org/47HjxhO

@handikawisnu You’ll find guides for Neovim and VS Code here: docs.astral.sh/ty/editors

@SamuelDiebolt Is there a guide I can follow to enable ty's lsp? Pyright crapped when I open my 20k+ loc files lol

ty is incredible for diagnostics AND as a language server! Orders of magnitude faster than Pyright and will eventually replace it. Still need Pyright for on-hover info for now, but we're moving toward a complete Astral-backed Python environment! ⚡

Although the question about lowercase vs uppercase "i" remains 🧐

🧠✨ Amazing #fUSbrainDAYS2025 conference! Thanks to the organizers for bringing together the fUSI community. Poll results (53 participants): 🏝️ Corsica vs Paris: 41 vs 11 🔬 fUSi vs fUS: 33 vs 14 Looks like we're heading to Corsica next year, and embracing #fUSI!

📍fUSbrain #DAYS 2025📍 🧠Day 1 of fUSbrain #DAYS 2025 is underway in Paris! This event brings together the international fUS community to share advances in brain imaging using functional ultrasound. We are proud to support the event as a sponsor, and to contribute to today's program and special evening cruise on the Seine River. ✨ It’s been a great day for the fUS community, and a chance to show our ongoing commitment to neuroscience innovation worldwide. #FunctionalUltrasound #BrainImaging #Paris2025 #Iconeus

In our new study just out in NeuroImage (doi.org/10.1016/j.neur…)we benchmark fUS against LSCI & show it captures age-related declines in neurovascular coupling and vascular density with superior resolution. Grateful to the whole team! @iconeus @OU_Neurosurgery @OUNeuroscience

1/ Six years in the making! Our preprint on SORDINO fMRI is out. We're sharing the raw data and sequence to facilitate brain-wide mapping in awake, behaving rodents. If this could be useful to your colleagues and friends, please help spread the word! biorxiv.org/content/10.110…

Can we use brain scans to identify biologically distinct "autisms"? And If so, how? In our latest cross-species study 🐭👨we dive into these questions! Find out more here 👇👇 biorxiv.org/content/10.110… Thread below 🧵 1/n

A lack of programming experience can derail experimental aspirations. Andrew Jahn shares how new educational tools that broaden both access and ease of use for neuroimaging are helping researchers fulfill their experimental ambitions. By Andrew Jahn thetransmitter.org/future-of-fmri…

🧠 Can diet impact brain health and neurodegenerative disease risk? A poor diet is a well-known risk factor for neurodegenerative disorders—but what is the underlying mechanism? 🔬 Groundbreaking research from @ESPCI_Paris and Université Paris Cité, using our Iconeus One fUS system, has provided direct imaging evidence of how a high-fat, high-sugar diet disrupts blood flow regulation in the brain. 💡 Key finding: This loss of functional hyperemia—critical for proper brain function—can be reversed with a dietary supplement that restores a healthy fatty acid balance. These exciting results pave the way for simple dietary interventions that could help maintain brain health and potentially reduce the risk of neurodegenerative diseases later in life. 👏 Congratulations to all the authors, including our Senior Scientific Application Specialist Haleh Soleimanzad, Hirac Gurden and Iconeus co-founder @TanterM, for this significant contribution to neuroscience! 📄 Read the full study here: nature.com/articles/s4136… #Neuroscience #BrainHealth #Neurodegeneration #fUSimaging #FunctionalUltrasound #Research #Innovation #Iconeus

🚨 fUSI-BIDS users Just a quick reminder that we're meeting today at 4:00 PM (CET) to discuss specification details and BIDSification challenges. You should have received an email with the meeting link, or you mail find it on the GDoc (docs.google.com/document/d/1W3…) See you all soon!
