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! 🤩

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

The supply of blood to brain tissue is thought to depend on the overall neural activity in that tissue, and this dependence is thought to differ across brain regions and across brain states. However, studies supporting these views have measured neural activity as a bulk quantity and related it to blood supply following disparate events in different regions. Here we measure fluctuations in neuronal activity and blood volume across the mouse brain, and find that their relationship is consistent across brain states and brain regions but differs in two opposing brainwide neural populations. Functional ultrasound imaging (fUSI) revealed that whisking, a marker of arousal, is associated with brainwide fluctuations in blood volume. Simultaneous fUSI and Neuropixels recordings showed that neurons that increase activity with whisking have distinct haemodynamic response functions compared with those that decrease activity. Their summed contributions predicted blood volume across states.Brainwide Neuropixels recordings revealed that these opposing populations coexist in the entire brain. Their differing contributions to blood volume largely explain the apparent differences in blood volume fluctuations across regions. The mouse brain thus contains two neural populations with opposite relations to brain state and distinct relationships to blood supply, which together account for brainwide fluctuations in blood volume.

When it comes to blood flow in the brain, not all neurons are created equal. Rather, only a subset of neurons may be driving vascular changes, a new study finds. By @claudia-lopez.bsky.social #neuroskyence www.thetransmitter.org/neurovascula...

Arousal neuron activity explains brain blood flow in mice

The findings could impact how researchers interpret signals from techniques that use blood flow as a surrogate for neural activity.

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

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.
