I had the privilege of working with Dionnet on this work. Such a pleasure! Pay attention to this one!

My PhD work on how lateral septum cells and circuits process threat cues to guide defensive actions is now online at @nature.com rdcu.be/fjNgT w/ @gordfishell.bsky.social and others

Thoughts on Anthropic and the pentagon....The US military has 3000 strikes in Iran, all determined using Claude's help -assume 94% accuracy and 0 hallucinations. So 180 errors in targeting. How many civilians are killed in those errors? That is why we can't autonomize warfare!

Excited to be on the organization meeting for the 6th annual NCM conference on Neural Circuits in Health & Disease. Terrific line up of speakers!

Excited for the publication of our recent work on how pyramidal cells shape the identity of interneurons in the Cortex! Big shout out to @artofbiology and Sherry Jingjing wu! www.nature.com/articles/s41...

Pyramidal neurons proportionately alter cortical interneuron subtypes - Nature

Pyramidal neuron-driven mechanisms actively promote the survival and terminal differentiation of their associated interneuron subtypes.

Thrilled to see our PNAS paper featured in @giacomoi.bsky.social commentary. A fantastic recognition of how biologically grounded cortical microcircuits can accelerate the next generation of NeuroAI—and a meaningful step connecting it to neuroscience www.pnas.org/doi/10.1073/...

And now the Neuromorphic piece has been picked up a one of the 10 most notable AI papers this week! Exciting! Well done Suraj!! aiworld.eu/story/this-w...

Well to complement my son's efforts here is some background into my own first foray into neuromorphic computing. The original article can be seen in PNAS! A big shout out to Suraj Honnuraiah, who made it all happen! www.growkudos.com/publications...

Well when it rains it pours. My son Will @fishell_will , just published a paper on biorxiv, much closer to my heart with my lab member Suraj Honnuraiah on spiking neural networks and understanding why they struggle as LLMs. www.biorxiv.org/content/10.1...

SNNs Are Not Transformers (Yet): The Architectural Problems for SNNs in Modeling Long-Range Dependencies

Spiking Neural Networks (SNNs) have gained increasing attention for their ability to operate on low-power neuromorphic hardware, offering a pathway toward energy-efficient large language models (LLMs)...

In a whimsical review of his arXiv.org paper, my son Will discusses the use of TempoBench in evaluating LLMs. I particularly enjoyed the faux ad for the TempoBench "product". You go Will! wfishell.github.io/landing.html

Really excited to see my son Will @fishell_will publish his first work Tempobench that measures temporal causality and reasoning in LLMs. arxiv.org/abs/2510.27544

Mechanics of Learned Reasoning 1: TempoBench, A Benchmark for Interpretable Deconstruction of Reasoning System Performance

Large Language Models (LLMs) are increasingly excelling and outpacing human performance on many tasks. However, to improve LLM reasoning, researchers either rely on ad-hoc generated datasets or formal...

New updated on how pyramidal neurons impact interneuron subtypes. Turns out spontaneous activity, Wnt signaling in PV Interneurons and integrin-signaling in SST neurons are the culprits! Also see how optimal transport tracks identity.https://www.biorxiv.org/content/10.1101/2024.07.20.604399v2

I am so excited about this combined analysis of the selective CRHR2 population within the lateral septum and how they control defensive behavior. Dionnet was truly a gifted graduate student. Keep your eyes on this one!

At my last year of attending the McKnight conference. Such an amazing group of scientists. A big shout out to Lauren Orefice who gave an amazing talk this morning!

Here is a chat with Bosilijka Tasic and myself about the enhancer-mediated AAVs that we were both centrally involved in publishing. I truly believe these approaches are fundamentally important for both basic and clinical approaches! braininitiative.nih.gov/news-events/...

Our recent paper in Science was co-led by @sandehaan.bsky.social, former PhD student in a @ki.se -NIH project. NIH support for international projects is transformative, seeding dynamic collaborations, and looks like it may stop. It is with great sorrow that I watch the dismantling of US science.

In the battle against brain disease, researchers can now rely on a new arsenal of genetic tools – The Armamentarium. Together with scientists from across the NIH BRAIN Initiative, we’ve created and published over 1000 new enhancer AAV vectors. 🧠📈

Here is the collective effort of 12 labs, lead by my own at the Broad to target the range of cortical interneuron subtypes! These tools should be a game changer for all of you using NHP and other less genetically amenable species! Have at it! urldefense.proofpoint.com/v2/url?u=htt...

Check out the neuroview and all the great articles of new tools to target different cell types with enhancer-mediated AAVs!

I will fly to anywhere in the United States on my own dime to talk to people about basic science! I encourage all of you, particularly senior scientists to make this commitment. If you are looking for material ask @karalmarshall.bsky.social She has put together an amazing basic talk!

Gord Fishell@gordfishell.bsky.social · last yr.

OK inspired by @karalmarshall.bsky.social I am reaching out to the public where ever I can. Traditionally Republicans have been incredibly supportive of science. We as scientists need to reach out to people across the spectrum to rally their support for basic science!

Ask Kara for this talk! It is an amazing walk through for the general public.mmI am going to give a general talk to the public every time I am traveling through the USA. I have had a wonderful career. It is my students and postdocs I am worried about 🥺. Come help out!

Gave a talk at my parents’ retirement community to describe how science is done, and what is at stake. There was a ton of interest, and anyone can do this. Get the word out about how science affects everyone. I’m happy to share slides with anyone who asks- just get in touch! youtu.be/BY_SFgi-Cig

Given all that is going on consider this quote from Bertram Russell's 1930 book The conquest of Happiness: “The man who can be interested in the structure of atoms or the way in which a beetle navigates, is likely to get a joy in life which no amount of success in the pursuit of power can give. ”

Heads up: A ton of papers from my group at the Broad, Pittsburgh, Irvine, Caltech, Duke, Berkeley and especially the Allen are on deck for a big consortium publication on new methods to target range of specific neuronal and non-neuronal cells coming out in Neuron and associated journals May 20th!
