"Evaluation of temperature elevation associated with low-intensity focused ultrasound (LIFU) stimulation with or without a deep brain electrode" Letter to the editor of Brain Stimulation. Rao et al. 2025.
brainstimjrnl.com
Low-intensity focused ultrasound (LIFU) uses low-energy acoustic waves to transiently modulate neuronal activity. Tissue heating from LIFU has been reported to be < 2 °C at up to 12W/cm2 [1] which is...

Just out in TMS: Here we explain in more detail the differences between NCG-TMS and Heart-Brain Coupling in response to work from Mark George's group on heart-rate as a biomarker for TMS. Together with @Jcoetzee and @NolanRyWilliams

Mourning the loss of Dr. Nolan Williams, who passed away unexpectedly October 8th. He was an extraordinarily creative physician-scientist who created highly effective treatments for psychiatric disorders. For me, he was also a mentor and a friend. He will be sorely missed.

Does the brain’s state before stimulation shape its response? 🧠⚡ Check out our latest preprint 👇 https://t.co/DLLiztf6gT w/ @GRabuffo @MariannaAngiol1 @FukaiTomoki @GustavoDeco @PierpaSorre
🧠⚡️Brain stimulation is powerful, yet its effects are notoriously variable: identical parameters can produce very different outcomes. In our new preprint, we show how the brain’s state before stimulation helps explain and reduce this variability. 1/n https://t.co/ouVuQGn77c

And there it is! #SB79, Sen. Scott Wiener’s bill to legalize multifamily housing near major public transit stops across California, just passed the state assembly! We are one vote away from the most significant shift in land-use policy California has ever seen!

🧠 We treat depression with TMS, but don't understand how it works. Our team tracked brain changes during Stanford Neuromodulation Therapy (SNT) and found treatment reduced brain excitability by 40%, with predictive changes by day 3. Progress moving from guesswork to precision
