New research from #DellMed's @GregFonzo "opens a new frontier" in the use of non-invasive deep brain stimulation for psychiatric treatment. His team used focused ultrasound to modulate amygdala activity, with patients seeing improvement across conditions. bit.ly/430Og66

Compelling testimony in committee from @w_bryan_hubbard of the American Ibogaine Initiative, Navy Cross recipient and retired @USNavy SEAL @MarcusLuttrell, and Dr. @GregFonzo of the @UTAustin @DellMedSchool Center for Psychedelic Research & Therapy in support of SB 2308. SB 2308 enables support for IND-approved clinical trials on Ibogaine—advancing evidence-based solutions to address the mental health and addiction crises impacting our communities, especially among military veterans. It's time to pursue real results with proven innovation.

Our focused ultrasound (FUS) #neuromodulation paper now out in @molpsychiatry! Low-intensity FUS attenuates #amygdala fMRI BOLD signal. Broad therapeutic effects in patients with once-daily FUS. Next up, the RCT! Thanks to @OneMindOrg, who funded this! rdcu.be/ejcYD

These findings open up new possibilities for non-invasive #brain-based treatment of a whole family of psychiatric disorders characterized by abnormal amygdala function. Though the FUS/fMRI findings were double-blind, we need to replicate clinical effects in an RCT.

This was a huge team effort! Big thanks to the X-less Lauren Enten, Annie DeMarco, Rachel Kline, Charles Nemeroff, Bryan Barksdale, & X-friendly @ManojDoss. Excited to see the next set of papers on amygdala FUS from @NoahSPhilipMD!

Replying to @PlazaLasVegas
@PlazaLasVegas is an awful, predatory hotel. They will charge you $500 for a supposed in-room smoking fee based on some automatic detection system (freshairsensor.com/technolog…) that has no white paper or credible evidence base whatsoever. No recourse either. Stay elsewhere.

The manager of the hotel could not even tell me what the detector is measuring, nor when it was last calibrated. Absolute predatory practice. I didn't even know about the charge until I got an automated credit card alert. I had to go inquire about it. Terrible, terrible hotel.

"What is the special sauce here that results in clinical efficacy? Is it the drug, the therapy, or the combination?" Read more from a special issue of The American Journal of Psychiatry on psychedelic medicine, edited by Charles Nemeroff & @GregFonzo. bit.ly/4htRX9I

If you’re at #ACNP2024, check out our posters on focused ultrasound on Tuesday night. I’ll specifically be trying to explain my way out of an unexpected finding in which we inhibited the amygdala and somehow enhanced episodic memory encoding.
