Thank you to everyone sharing in this moment! I’m so grateful to all my trainees & collaborators… dlab.stanford.edu/group-members (pic: Peter and I together in 2017) Reading for all those asking: for technical details: dlab.stanford.edu for everyone: deisseroth.org/projections

At long last! I'm excited we can finally share the final published form of CURBD, our method to disentangle multi-regional interactions with RNNs, out today in Neuron. Thanks to @kanakarajanphd.bsky.social and @deisseroth.bsky.social and all of our collaborators! 📃: doi.org/10.1016/j.ne...

Congratulations @kangyongloh.bsky.social, Spencer Zhao, @carolynbertozzi.bskyverified.social, and the whole team– including my longtime and wonderful collaborator Zhenan Bao– for this key step in our journey toward genetically-targeted chemical assembly in biology. www.nature.com/articles/s41...

Please join us in welcoming incoming chairs @tinakim-neuro.bsky.social & @gisellavetere.bsky.social, and newly elected vice-chairs @tristanshuman.bsky.social & @lindsayschwarz.bsky.social. We can’t wait to see what this team has in store for #OptoGRC2028!

We can't wait to hear from #OptoGRC2026 keynote speaker, Sheena Josselyn! Be sure to catch her Sunday evening talk exploring engrams and how memories are encoded in the mouse brain 🐭 🧠 Haven’t registered yet? Applications are still open through April 12 👇 www.grc.org/optogenetic-...

Get ready to map behavior in motion at #OptoGRC2026 🧠📊 With discussion by @neurrriot.bsky.social & speakers Christian Lüscher, @honglab.bsky.social, @biancasilvalab.bsky.social & @derynleduke.bsky.social, this Tuesday PM session highlights innovative ways to monitor, model & make sense of behavior.

Great work from Claire, Ravi, and the whole team– the initial lifelong continuous screen of behaving vertebrates provided a wealth of ideas on progression/staging of brain function across lifespan. Behavior is unmatched as a noninvasive quantitative readout of brain function (and, one that matters).

Thank you @samvesuna.bsky.social‬ and the whole secret cake team! And congrats to all the amazing laboratory and clinical presenters from our program– the surprise cake got us through (I had forgotten how physically challenging being a poster presenter can be). I'll train harder for next year...

We had the most amazing 25 year lab anniversary today. Blown away by the science from my alumni and very proud of the current members. The community they have built is remarkable and it felt like a family reunion. The tacos, drinks, cake, and jazz were pretty great too.

It's time to meet your #OptoGRC2026 chairs! Co-vice chair @tinakim-neuro.bsky.social is an assistant professor at @princeton.edu who spent the summer building a van for weekend adventures 🚐✨ She's most looking forward to meeting new people & exploring areas outside of her usual wheelhouse!

Our microbial-opsin work (and most of the field ) is basic science, but it was intriguing to review clinical progress–direct & indirect–with a wonderful team of co-authors t.co/JrJen2WGBV & adapt a fig. of PMID:28912215 (2017) with my long-time collaborator Peter Hegemann (pic: a memory from 2017).

Amazing collaboration with @alleninstitute.org team—@hongkuizeng.bsky.social, Bosiljka Tasic, Tanya L. Daigle, La'Akea Siverts—to develop new transgenics for all-optical neuroscience. And deeply grateful to @deisseroth.bsky.social for his support and mentorship. 🙏 12/13

✨ New preprint ✨ What if we could watch AND control thousands of individual neurons in behaving mice—with stable access over months? 🧠⚡ Our work introduces transgenic all-optical tools that make this possible - and a resulting surprising discovery! 🔭💡 www.biorxiv.org/content/10.1... 1/13 🧵

Big thanks to all the co-authors. Huge shoutout to Tony Drinnenberg, Charu Ramakrishnan and @deisseroth.bsky.social as well as the team at @alleninstitute.org. This would not have been possible without their new mouse lines. Check out this preprint for more information: doi.org/10.1101/2025...

Our new paper "High-capacity associative memory in a quantum-optical spin glass." Achieves 7-fold increased capacity thru a quantum optical analog of short term plasticity from neuroscience. Atoms (neurons) couple to motion and photons (synapses)! arxiv.org/abs/2509.12202

Celebrating the 100th anniversary of the Scopes trial telling students in central Tennessee about their inner fish. I’m so grateful to the high school and middle school teachers who brought their students from small schools to the event (some from almost an hr away).

congratulations Neil! NAS is lucky to have you leading the way...

HHMI Tangled Bank Studios brings science to life through powerful, visually stunning storytelling.✨ For over a decade, @tangledbankhhmi.bsky.social‬ has delivered award-winning films that engage audiences with the wonder, complexity, and importance of science.

📆 Mark your calendars: #OptoGRC2026 is headed back to Tuscany, May 10-15, 2026! We look forward to reuniting with our amazing community for a week of great science, thoughtful discussions & shared time with colleagues. More details coming soon👇🏽 tinyurl.com/esvrabsu

New paper from the lab: Our teeth arose as sensory organs on the outside of the body of ancient jawless fish.!! Congrats to Yara Haridy and the team! Background and video: phys.org/news/2025-05... Open Access Paper: www.nature.com/articles/s41... News and Views: www.nature.com/articles/d41...

Unforgettable moments honoring @deisseroth.bsky.social, recipient of the Asan Award in Medicine! Watch this great video highlighting his groundbreaking contributions: www.youtube.com/watch?v=tOzK... Proud to celebrate this historic achievement in Seoul. Cheers, Karl! 🎉 #AsanAward #Neuroscience

Congratulations to these two outstanding physician-neuroscientists! Many people now are familiar with the fascinating fundamental research of @michellemonje.bsky.social but most people probably don't know she is a truly great physician. I'm fortunate to be inspired by her every day, in every way.

I am hiring: PhD students, postdocs, admin personnel. Email me if you know somebody that may be interested in joining us in Cologne! 👇👇 Please RT for reach! 🙏🙏

strongly recommend this book... @neilshubin.bsky.social is a great communicator and scientist. We're coming up on the 10 year anniversary of this special moment from February 2015: Neil showing the Tiktaalik fossil to a few of my entranced kids.

Combined analysis of #GWAS and human brain single-cell transcriptomics data to infer the cell-types involved in the etiology of #schizophrenia and other psychiatric disorders 🧪🧠 www.nature.com/articles/s41...

Welcome to Bluesky! and thank you @sykneuro.bsky.social‬! Of course, I was the lucky one, honored to have you in my lab... Looking forward to seeing you again in March!

663 days since the senseless tragedy that took An, we present a manuscript that reports some of the discoveries that she left us. www.biorxiv.org/content/10.1...

Eric @erictopol.bsky.social has deep biomedical knowledge and remains a trusted science communicator, loyal to facts while others veer off. Importantly, he finds these interviews fun—I sure enjoyed talking to him about life, science, and what I’ve learned along the way.

Group selfie after our presidential plenary session at @acnporg.bsky.social this morning in Arizona at the invitation of ACNP President Helen Mayberg! With wonderful speakers Michelle Monje, Botond Roska & David McMullen speaking on advances that accelerate translation in neuropsychiatry!

Preprint dropped! Excited about this study by Yu Wang, a PhD student from Li Ye's lab and mine, now a postdoc in @deisseroth.bsky.social lab. It unveils an unexpected role for PIEZO2/mechanosensation in sensory neurons that innervate fat! What is it sensing in fat? www.biorxiv.org/content/10.1...
