We used rabies virus 👾 to map how #psilocybin modifies long-range circuits 🧠, revealing network-specific reorganization that we didn’t expect.
Full study now online at Cell @CellCellPress
Paper 👉 doi.org/10.1016/j.cell.2025.…
Thread for a synopsis 👉 teapawt.net/kwanalexc/status/19534…
New preprint + thread 🧵
#Psychedelics induce the formation of new synapses, but where do they connect?
Our rabies tracing study reveals that #psilocybin shifts connectivity across specific cortical networks.

For us, #OpenScience also means investing in sharing our resources and techniques with the community through courses like the Summer Workshop on the Dynamic Brain.
Happy #OpenScienceWeek!
Recently wrapped up two incredible weeks of intense team 🧠 science on San Juan Island 🌲🌊 @ the Dynamic Brain Workshop by @AllenInstitute. Easily the best learning experience I’ve ever had—huge thanks to the organizers, and deep gratitude for the community, ideas, & teamwork 🙏

My lab with @MontrealRobots was honoured to present our recent research and explain how machine learning enables robotics that will drive innovation in Canada. It was a pleasure getting into the details!
We were delighted to welcome the Honorable @MarkJCarney and @EvanLSolomon to Mila today for a rich discussion on AI's potential to drive innovation, social progress, and economic resilience in the country, alongside key players from our ecosystem.

In case you can't make it to Amsterdam, check out
@VeronicaChelu's talk from earlier this year at the #KempnerInstitute's #NeuroAI2025 symposium.

Looking forward to presenting my research on Excitatory-Inhibitory Dynamics in Adaptive Decision-Making @ the 'RNNs Making Decisions' workshop @ #CCN2025 later today (sites.google.com/view/rnnsma…) and a poster Wed, Aug 13, during the main conference.

#CCN2025 is starting tomorrow in Amsterdam, and our lab is presenting and contributing in several ways. A summary thread:

Planning to attend #CCN2025 in Amsterdam next week? Interested in recurrent network models of decision making? Then join us in our Satellite Workshop on Monday at 3pm. We'll have @summerfieldlab @veronicachelu and many more! sites.google.com/view/rnnsma…

Dispatch: The Neurobiology of Psychedelics Gordon Research Conference (Part 1)
200 psychedelic scientists met in Rhode Island to discuss the field via the first Gordon Research Conference on psychedelics.

The first #GRCPsychedelics was referred to as the Woodstock of conferences. Feeling extremely lucky to learn from pioneers of psychedelic neuroscience, and get to know so many of the legends and new scientists who are making discoveries in this exciting field.
Veronica Chelu retweeted
Easily one of the best conferences I have attended so far! @GordonConf
Shout out to the leadership of @kwanalexc @VVyazovskiy @MelissaHerman4 @ViditaVaidya
This experience had so many highlights (but apparently, I can only post 4 pictures in one post). #GRCPsychedelics

In 1993, it was looking like the internet was actually going to be a thing, so I made a homepage for myself. This is what I wrote for my personal statement:
"I am seeking to identify general computational principles underlying what we mean by intelligence and goal-directed behavior. I start with the _interaction_ between the intelligent agent and its environment. Goals, choices, and sources of information are all defined in terms of this interaction. In some sense it is the only thing that is real, and from it all our sense of the world is created. How is this done? How can interaction lead to better behavior, better perception, better models of the world? What are the computational issues in doing this efficiently and in realtime? These are the sort of questions that I ask in trying to understand what it means to be intelligent, to predict and influence the world, to learn, perceive, act, and think."
The point being that is was always all about experience for me.

The brain as it's never been seen before.
Scientists have created the largest wiring diagram and functional map of a mammal brain to date.

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. 🧵

Neuroscientists have observed for the first time how structures deep in the brain are activated when the brain becomes aware of its own thoughts

Rich's slogans for AI research (revised 2006):
1. Approximate the solution, not the problem (no special cases)
2. Drive from the problem
3. Take the agent’s point of view
4. Don’t ask the agent to achieve what it can’t measure
5. Don't ask the agent to know what it can't verify
6. Set measurable goals for subparts of the agent
7. Discriminative models are usually better than generative models
8. Work by orthogonal dimensions. Work issue by issue
9. Work on ideas, not software
10. Experience is the data of AI
