My co-authors have yet to move to Bluesky, so I'm pleased to announce our latest work has just been published in @nature.com Neuroscience. Amazing work led by Junheng Li, revealing that falling asleep follows a predictable bifurcation pattern #neuroskyence #sleep www.nature.com/articles/s41...

Tomorrow, Sept 19 | 3:30 PM, at #CCNP2025 (ccnp.ca) in Montreal, I’ll be co-chairing the symposium “Psychedelics & Psychiatry” 🍄🧠 with @swubat.bsky.social. We’ll explore how psychedelics reshape brain circuits & behavior, bridging preclinical & clinical perspectives.

🧵Recently wrapped up two incredible weeks of intense team 🧠 science on San Juan Island 🌲🌊 @ the Dynamic Brain Workshop by @alleninstitute.org Easily the best learning experience I’ve ever had—huge thanks to the organizers, and deep gratitude for the community, ideas, & teamwork 🙏

Looking forward to presenting my research on Excitatory-Inhibitory Dynamics in Adaptive Decision-Making @ the 'RNNs Making Decisions' workshop later today (sites.google.com/view/rnnsmak...) and a poster Wed, Aug 13 @ #CCN2025 🙏 @jorgefmejias.bsky.social @molanomazon.bsky.social

We start strong on Monday at 15h, when we organize the Satellite Workshop 'RNNs making decisions' together with @molanomazon.bsky.social. Speakers @summerfieldlab.bsky.social, @veronicachelu.bsky.social, @seanfw.bsky.social and others: sites.google.com/view/rnnsmak...

If you are planning to attend #CCN2025 in Amsterdam next week and are interested in recurrent network models of decision making, please join our Satellite Workshop on Monday at 3pm. We'll have @summerfieldlab.bsky.social , @veronicachelu.bsky.social and many more! sites.google.com/view/rnnsmak...

Seriously, though, the actual principle needs to be: only request letters of reference for shortlisted candidates. The amount of unnecessary work created by forcing every single applicant for everything in academia to get 2-3 letters of reference is mind boggling. What a waste of everyone's time...

Had a fantastic time at the Neurobiology of Psychedelics GRC. Only a week yet feels like it could have been months. New community, new lab, novel and diverse ideas and perspectives, unpublished brand new research, a lot of growth. Easily one of my favourites #GRCPsychedelics

I had a great time at #GCRpsychedelics, discussing our data on the non-hallucinogenic derivative of LSD, alongside a stellar panel of researchers! Very grateful to @alexkwan.bsky.social and @vladvysotsky.bsky.social for inviting me and putting together a very exciting program!

Somehow we got almost all the students and postdocs in one photo!! Until next time #GRCPsychedelics 🫡

Had a lovely time at #GRCpsychedelics Only took pics of bunnies, sunsets, and @cllantz.bsky.social Already looking forward to 2027!

The inaugural #GRCPsychedelics was a success! I am honored to have been one of a few chosen to receive a travel award and be able to share the stage with the leaders in the field. 🙏 to the organizers! @alexkwan.bsky.social @vyazovskiy.bsky.social @melissaherman.bsky.social @viditavaidya.bsky.social

So happy the first #GRCPsychedelics was such a success. It was great to see everyone and share all the amazing science and community. Thank you to all the speakers and congratulations to the travel awardees!!

Had a blast at the first ever #GRCPsychedelics - thanks so much to Chairs @alexkwan.bsky.social @vyazovskiy.bsky.social & Vice Chairs @melissaherman.bsky.social @viditavaidya.bsky.social for bringing our community together 🫶 Per usual, I took no pics - but luckily Missy had it covered for me 😂

Fun unexpected dinner experience at the end of #GRCPsychedelics 🦞

Excited to attend Neurobiology of Psychedelics GRC this week! Looking forward to deep dives into the mechanism of action of psychedelics and how they modulate neuroplasticity, cognitive flexibility, and adaptive decision-making—across behavior and neural dynamics. 🧠🍄 #GRCPsychedelics

Just got back from Tokyo, where I learned many fascinating things about synaptic plasticity, dynamics of decision-making, the role of astrocytes in neural computation, just to name a few @ RIKEN Center for Brain Science during the summer program on Neural Circuits: Coding, Computation & Cognition 🧠

Had a lot fun last week @ IRCN, @ University of Tokyo during the Neuro-inspired Computation Course 2025 🧠🤖✨

Back from @psychedelicscience.bsky.social by @mapsorg.bsky.social in Denver, Colorado—energized by the convergence of neuroscience, psychiatry, psychopharmacology, and data-driven approaches to psychedelic research. Grateful to be part of this evolving conversation. #PS2025 #MAPS 🧠✨🌀🍄

NEW: Veronica Chelu ( @veronicachelu.bsky.social‬ ) from @mcgilluniversity.bsky.social‬ shows how excitatory-inhibitory dynamics in recurrent neural networks can affect decision making and reinforcement learning. Watch the video: youtu.be/NnKmVObJJUQ #NeuroAI2025 #ML #neuroscience #NeuroAI

🧵Grateful for the opportunity to present @harvard.edu's Frontiers in NeuroAI Symposium @kempnerinstitute.bsky.social on how decision-selective E/I dynamics shape adaptive learning & decision-making 🎥 Talk youtu.be/NnKmVObJJUQ 📄 Abstract tinyurl.com/yxvtn39v 🖼️ Poster tinyurl.com/mu3r24vx

Next was a short talk by @veronicachelu.bsky.social on modeling neural system excitatory-inhibitory dynamics at the @kempnerinstitute.bsky.social www.youtube.com/watch?v=NnKm... (3/14)

Just landed in Dublin 🇮🇪 for @rldmdublin2025.bsky.social ! Looking forward to presenting my research on “Excitatory/Inhibitory Dynamics in Adaptive Decision-Making” and chatting about all things neuroscience, RL, and decision-making. Hope to see you around! #RLDM2025

New preprint! 🧠🤖 How do we build neural decoders that are: ⚡️ fast enough for real-time use 🎯 accurate across diverse tasks 🌍 generalizable to new sessions, subjects, and even species? We present POSSM, a hybrid SSM architecture that optimizes for all three of these axes! 🧵1/7

Excited for the Frontiers in NeuroAI Symposium tomorrow @kempnerinstitute.bsky.social, where I'll be presenting some recent work on Excitatory-Inhibitory Dynamics in Adaptive Decision-Making 🧠🤖 #NeuroAI2025

Our work with Pablo Tano, @hyunggoo-kim.bsky.social Athar Malik, Alexandre Pouget and @naoshigeuchida.bsky.social exploring how dopamine neurons could enable multi-timescale reinforcement learning in the brain is out in @nature.com www.nature.com/articles/s41...

Was just pointed to this important preprint from @minsanally.bsky.social : www.researchsquare.com/article/rs-4... tl;dr: classically "non-responsive" cells are preferentially recruited by top-down inputs and are critical for learning. So, my neuro-friends: Don't ignore untuned cells!!!! 🧠📈 🧪

Excited to share that I’ll be starting as a postdoc in @rcbagot.bsky.social’s lab at @mcgilluniversity.bsky.social, studying the neural mechanisms of psychedelics ✨🐁🌀 Grateful for this new adventure into the unknown.

Thrilled to see this part of my PhD work with @rcbagot.bsky.social now out in @natcomms.nature.com! (1/14) www.nature.com/articles/s41...

how fascinating!! 🧠🐁✨

How does the brain work? Scientists are closer to the answer with the largest wiring diagram and functional map of a mammalian brain to date. 🧵 🧠📈

I just sent a message to my MP, encouraging them to support #neuroscience research in the 2025 federal election during and after the election. I encourage you to do the same! Visit www.vote4brainhealth.ca for tools that make it easy. See also @cbrs-scrc.bsky.social 🧠📈 #canpoli

First day of spring marked new personal beginnings 🌱 PhD was the best of times...a wondrous trip 🥹, but I'm super excited to start a new chapter 😬

👏🎉✨

OK If we are moving to Bluesky I am rescuing my favourite ever twitter thread (Jan 2019). The renamed: Bluesky-sized history of neuroscience (biased by my interests)
