MR guided focused ultrasound surgery is an effective and uprising treatment option for Essential tremor. But where is the optimal site to sonicate? Which spots to avoid due to side-effects?

Two-thirds of Americans believe Trump has "gone too far" with ICE. The cruelty & extremism is out of control.

Our new ad features Joe Rogan asking "Are we really going to be the Gestapo?...Is that what we've come to?"

Check it out & share.
This is the ad that Fox News does NOT want you to see.

Fox News rejected our newest ad, which demonstrates that Trump has “gone too far” with ICE.

But we will not remain silent in the face of these attacks.

Share our ad and follow @usjewishdems.bsky.social to join us in the fight.

The highlight of my week was the publication of "Parkinson’s disease as a somato-cognitive action network disorder" in @nature.com. It's a great paper that shows how conceptual changes in fundamental neuroscience - the discovery of SCAN - can improve treatment 🧪 www.nature.com/articles/s41...
Parkinson’s disease as a somato-cognitive action network disorder - Nature
The substantia nigra and all Parkinson’s disease deep-brain stimulation targets are selectively connected to the somato-cognitive action network rather than to effector-specific motor regions.

🧠 Die Tiefe Hirnstimulation bei Parkinson zeigt ihre bestmögliche Wirkung, wenn ein präzises Gehirnnetzwerk im Beta-Frequenzbereich (20–35 Hz) stimuliert wird – das zeigt ein Team um @andreashorn.org @bahnebahners.bsky.social jetzt erstmals gleichzeitig räumlich und zeitlich👇

🧠 Deep brain stimulation for Parkinson’s disease achieves its best results when a precisely defined brain network operating in the high beta frequency range is targeted. This was shown by a team @andreashorn.org @bahnebahners.bsky.social in both space and time for the first time.👇

…well, should there be a difference? Both is terrible, especially if these are truly "random fishermen".. 🙄
He cannot be clearer. There is no difference to him between bombing random fishermen on boats and shooting Americans protesters in the face
I swear this clip is not edited. Trump pivots from downplaying the killing of Renee Good and Alex Pretti ("two people out of tens of thousands and you get bad publicity") to in the very next breath claiming "we've been very tough on the waters," leaving Tom Llamas baffled ("the waters?")

TRUMP: You are so bad. You are the worst report. No wonder CNN has no ratings. She's a young woman. I don't think I've ever seen you smile. They should be ashamed of you.

When I was entering the field of DBS, Ludvic Zrinzo said a few things that were simple in retrospect but formulated so clearly that they fundamentally changed how I think of the therapy. I am super grateful about this super insightful interview at @stimulatingbrains.org – tune in 👇👇
It was a great joy to talk to Ludvic Zrinzo about DBS, lesioning and how it all may work: stimulatingbrains.org/74-ludwig-zr...

Thanks to Niels Pacheco for producing the episode!

I’ve been mentoring a student in Europe who I was hoping would come do a postdoc with our research group in Pittsburgh when she graduated. Today we had the conversation that she isn’t comfortable coming to the US anymore and is looking for options in Europe.

It’s sad and yet completely rational.

This clip is great. The fact that this view isn't the default amongst scientists is so depressing.
There's the way Trump is gleefully happy to accept someone else's Nobel prize, and then there's the way Richard Feynman viewed Nobel prizes.

Deep brain stimulation can improve Parkinson’s disease symptoms, but selecting the optimal stimulation contact still relies on laborious trial-and-error.
