Humans of HBI - Satpreet (Sat) Singh I build "virtual model organisms” with artificial bodies and artificial brains that are trained to behave like real model organisms, such as insects and fish, in simulated worlds.

Meet Satpreet (Sat) Singh on #HumansofHBI

Organizers:
@satpreetsingh.bsky.social @anayebi.bsky.social Elliott Abe

Watch recordings from last year:

Topics include:
• Cognitive and Embodied RL agents modeling natural behavior, brains and ecology
• Learning dynamics, internal goals and interoception
• Bridging experiments, theory, and NeuroAI
• “Digital twin” musculoskeletal models for flies, fish, rodents & humans

📣 Excited to announce the 2nd edition of our workshop
“Agent-Based Models in Neuroscience: Theory, Autonomy, Embodiment & Environment”

2025: A Review of the Year in Neuroscience Enlightening the brain

Just published my review of neuroscience in 2025, on The Spike.

The 10th of these, would you believe?

This year we have foundation models, breakthroughs in using light to understand the brain, a gene therapy, and more

Enjoy!

Congratulations!!

Thrilled to start 2026 as faculty in Psych & CS
@ualberta.bsky.social + Amii.ca Fellow! 🥳 Recruiting students to develop theories of cognition in natural & artificial systems 🤖💭🧠. Find me at #NeurIPS2025 workshops (speaking coginterp.github.io/neurips2025 & organising @dataonbrainmind.bsky.social)

#NeurIPS2025 workshops are underway!

Today’s workshop presentations from the #KempnerInstitute cover a range topics, including the use of #AI in linguistics and the study of communication & sensing in electric fish.

#NeuroAI

Different seeds with same training loss doesn't always mean same solution. When do neural nets converge vs diverge? What are the implications for inverse problems, #AI4Science & #MechInterp?

Mid-conference momentum! 🔬📈

Today’s #NeurIPS2025 presentations from the #KempnerInstitute showcase a wide variety of research projects at the frontiers of #AI and #NeuroAI.

Survey: Which sources fund your neuroscience research? Government sources are the main contributors to neuroscience labs, but funding breakdown varies across labs, career stages and neuroscience subfields.

33 neuroscience researchers from across the world shared how their labs our funded, providing insight into the current state of funding and how that might shift.

We investigate how multi-agent NCAs can develop into artificial life 🦠 exhibiting complex, emergent behaviors like cyclic dynamics, territorial defense, and spontaneous cooperation.

In case you don't know already, the journal Open Mind has a Bluesky account that automatically posts new papers:

The journal is diamond open access (free to read, free to publish) thanks to the support of MIT Press, Harvard Library, & MIT Library.

Congratulations!! 🚀🚀

Differential kinematic coding in sensorimotor striatum across behavioral domains reflects different contributions to movement - Nature Neuroscience Hardcastle and Marshall et al. show that striatal function is domain specific, required for task-related but not spontaneously expressed movements. This functional distinction is reflected in starkly ...

For the past 3 years, I've taught a course on Machine Learning for Climate Change to undergrads. At times, people have asked if the course lectures could be made available online. While I can't offer that, I have decided to start making "5 Minute Papers on AI for the Planet" videos. Hope its useful!
