Was a lot of fun working on this piece with Ben Clayton for @annualreviews.bsky.social
Reactive astrocyte heterogeneity is a thoroughly exciting and complicated problem... lots of exciting discoveries in recent years.

Our work about glial induction of cerebral vasomotion during neuroinflammation is out in @ebiomedicine.bsky.social !
You can read it here: www.thelancet.com/journals/ebi...

As pictures are worth a thousand words, here is a movie of the typical inflammatory CBV changes, superimposed on an ULM image

Great article by @thetransmitter.bsky.social on making #neuroimaging tools accessible! As someone working in #fUSI, I strongly believe dedicated #OpenScience solutions are essential for our field to advance. Hope to contribute to these efforts in the future.​​​​​​​​​​​​​​​​

Nice to see the new album from my heavy metal band promoted here on bluesky 🎸
If you like old school stuff with Iron Maiden / Judas Priest vibes, worth to give it a listen!

Exclusive: NIH to terminate hundreds of active research grants Studies that touch on LGBT+ health, gender identity and DEI in the biomedical workforce could be terminated, according to documents obtained by Nature.

In an unprecedented move, the US National Institutes of Health (NIH) has begun mass terminations of research grants that fund active scientific projects because they no longer meet “agency priorities”….

Looking forward to this!

Thanks, I will take a look at it, looks cool!
Anyway this resonates with remarks from many other people that occasionnally see similar waves (brain or not) but do not study them further as they appear rather randomly in specific subjects. Hope this will renew the interest on this phenomenon!

Interesting that you found similar stuff outside the brain. Was there any correlation w/ local inflammation ?
Waves were restricted to small parts of the brain vasculature, similarly to some clinical observations with optical techniques.this made us think of local vasomotion rather than Mayer waves

The gamma rhythm as a guardian of brain health Fast oscillations (30-150Hz), generated by internal brain mechanisms may be essential for the maintenance of healthy brain function.

Induction of hemodynamic traveling waves by glial-related vasomotion in a rat model of neuroinflammation: implications for functional neuroimaging Cerebral hemodynamics are crucial for brain homeostasis and serve as a key proxy for brain activity. Although this process involves coordinated interaction between vessels, neurons and glial cells, it...

Happy to share these findings from a previous work in Lyon: #neuroinflammation can enhance vasomotion, resulting in large hemodynamic traveling waves during #fUSi. This was related to the local presence of reactive glial cells. #glia

Thanks to all involved!

This is a schematic of the first 'neuroimaging' machine, developed by Angelo Mosso in 1882. It was a very carefully calibrated balance, which aimed to measure small changes in the balance due to changes in blood flow. #neuroskyence #psychscisky

🧠 barriers & neurovasculature starter pack - please reply here if you are not on it yet & would like to be added 😊 go.bsky.app/RB6RXKy

You wanted starter packs to be searchable. Our engineers are busy keeping us online, so in the meantime, an independent developer built a new searchable library of starter packs. This is the beauty of building in the open 🦋

Gentle reminder: even if you don't mask regularly, please mask inside airplanes.
