My paper is out!! 🎉 "Opponent control of reinforcement by striatal dopamine and serotonin", @Nature Here, we show that dopamine and serotonin signals form a gas-brake system for reward in the mammalian brain 🧠 THREAD ⬇️ 1/n

1/5 Excited to share our new paper where we used a rare selection of direct recordings from the human thalamus to understand its role in coordinating high frequency oscillations, called ripples, in the cortex and hippocampus during sleep. plos.io/3UYXnkb

The #thalamus syncs spindles & Up states in cortex for memory, but what about co-ripples in #hippocampus & neocortex? @cdickey_ &co show that during human sleep, thalamic spindles & Up states sync networks that regulate #memory consolidation #PLOSBiology plos.io/3UYXnkb

We were curious about how much drug and medical device companies compensate psychiatrists, so we looked into it. Here is what we found. psychiatryonline.org/doi/10.1176/ap… @APAPubJournals

This week, the Stanford Bio-X Undergraduate Summer Research Program featured 3 more amazing faculty talks, from Dr. Helen Blau, Dr. Jason Tucciarone, and Dr. Vivek Buch ( @VivekBuchMD )!

We spent hundreds of hours recording neural activity from sleep and arousal-related cell types in the deep brain, all while delivering variant focused ultrasound pulsing schemes to gain insight into one of the most daunting questions in the field: 'What are the parameters?'.

Now out in @brainstimj from @KellerStanfordU and @boeslab! What does TMS do to the human brain? Using a combination of intracranial EEG and TMS, we published one of the deepest explorations of TMS-related change in human neurophysiology to date. 1/7 🧵brainstimjrnl.com/article/S1935-…

This project blew me away from day 1…I am still so fascinated! And grateful to be part of such a fantastic group effort.. Congrats @BelginYalcin_ @michelle_monje and the rest of the team !

Can whole-brain imaging of cellular c-Fos signals be used for #psychedelics drug discovery? This was a project led by @aboharbf and @PashaDavoudian, where they tested a panel of drugs and developed a machine learning pipeline to classify. biorxiv.org/content/10.110…

As promised, here is a 2-minute summary of my newly published paper: “MDMA enhances empathy-like behaviors in mice via serotonin release in the nucleus accumbens.” Science is not complete until it’s communicated! 🗣️ Enormous thanks to @MoeNeuro, @TheBorisLab, & Rob Malenka

Thrilled to share that my postdoc work from the Malenka lab is out today! Of course, this work will not be complete until it’s communicated. Short video summary coming soon science.org/doi/10.1126/sc…
