Hi co-activation patterns people! I've been playing around with CAPs recently and wanted to sanity-check something. My understanding is that CAP vs. anti-CAP is usually interpreted not as "activation vs. no activation", but as two opposing configurations (two poles of the same fluctuation).

napari is such an incredible piece of scientific software! 🚀 And it's not just for visualizing static data. I've been using it for the past 6 months to drive a @verasonicsinc.bsky.social ultrasound system for #fUSI, and get a nice GUI for sequence control and live visualization! 🤩

Struggling for something to do in a TWO DAY gap without ⚽? How about trying our pre-release of napari 0.8.0? napari.org/dev/release/... Of note, this release drops Py3.10 support and deprecates PyQt5 in favor of PyQt6. It also adds some neat new features and improvements! See below: 👇

Remember folks: you can ship some of the most advanced LLMs on Earth, but choosing distinguishable colors for a plot remains an open research problem. openai.com/index/previe...

Losing one side of Superior Colliculus is bad, but losing both sides seems fine. Wait, what? Flora & team discovered why: both sides press for contra actions and against inaction, obeying an incredibly simple additive rule. Out today in bioRxiv: www.biorxiv.org/cgi/content/...

Interesting article on something I think is very relevant to open science: several teams analyzed the same ephys dataset and got quite different answers. Not because the analyses were bad, but because this kind of work involves many analysis choices, and those choices can change the result.

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states! Out today in Nature: rdcu.be/fdC2A @uclbrainscience.bsky.social

Want to explore connectivity & projection patterns yourself, like we do here? We released brain_street_view to let you pick any injection site in the Allen Connectivity Atlas and visualize where it projects in your favorite region of interest: github.com/Julie-Fabre/brain_street_view

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 opto manipulations of the locus coeruleus, pointing to a minor role for noradrenergic tone. www.biorxiv.org/content/10.6...

New paper out 🎉 Awake fUSI is powerful, but motion can strongly bias the data, even in head-fixed experiments. In this paper, we tried to systematically characterize those artifacts, benchmark denoising strategies, and turn that into practical recommendations for awake fUSI of mouse brains. 1/12
