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...

[May 24, 2022] Happy to say our ultrasound paper is now out in Brain Stimulation doi.org/10.1016/j.br... We used cultured neurons to dissect mechanisms of ultrasonic neurostimulation. Most surprising: even an extremely short (4µs) single low-intensity pulse can generate neuronal activity.

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 🧠🫀🫁🤯
A non realistic illustration in which some researchers are working around a brain at least 5 times bigger than a human. They are positioning an ultrasound probe on the top to measure heart and breathing rate. We see literally, heart and lungs inside the brain.
