Delighted to see that @ohbmossig.bsky.social has confirmed dates for the 2026 @ohbmofficial.bsky.social brain hack!
ohbm.github.io/hackathon2026/ 11-13 June Thur-Sat, in the usual 3 days before the meeting, at the Campus Victoire, University of Bordeaux

Looking forward to it!

We can do without them: how the UG is cutting ties with Big Tech By 2030, the university aims to be digitally independent. And that’s not a pipe dream, say proponents of the plan.

University of Groningen: ⭐ no more big-tech by 2030 ⭐ Google Workplace 🚫 Windows 🚫 MS Office 🚫 ChatGPT 🚫 A huge challenge! Meeting culture won't get us there. Dedication and focus will. 💪🚀 Let's get to work.

Anyone have a thought about this weird mol on my hand?

We need more tools in this spirit to help make sense of science.

Thank you so much @markcembrowski.bsky.social, your own reviews on the subject of neural heterogeneity have provided excellent starting conditions for our work!

thank you very much, David Dahmen, Axel Hutt, @giacomoi.bsky.social, @antihebbiann.bsky.social, Jeremie Lefebvre, Luca Mazzucato, Adilson E. Motter, Rishikesh Narayanan, @melikapayvand.bsky.social, and Henrike Planert, this has been wonderful learning experience, and I hope it serves the field!

Another contribution to this question is the study of how different aspects of neural network heterogeneity impact the dynamic and computational properties of these networks. This is what my co-authors and I are attempting in this perspective.

Electrophysiological classification of human layer 2–3 pyramidal neurons reveals subtype-specific synaptic interactions - Nature Neuroscience Using multineuron patch clamp in human cortex, the authors uncover four functional subtypes of pyramidal neurons with distinct morphology and subtype-specific synaptic interactions, revealing conserve...

See recent work from Henrike Planert, one of our co-authors, for example www.nature.com/articles/s41..., as well as the work by @markcembrowski.bsky.social and @nspruston.bsky.social on the relationship between transcriptomic and electrophysiological cell identity www.nature.com/articles/s41...

It's a fundamental question of neuroscience how brain function emerges from its diverse networks of neurons. One contribution to this question is to characterize neurons in terms of their electrophysiology, morphology, etc., including the relationships between those properties.

How heterogeneity shapes dynamics and computation in the brain No two neurons are the same, yet models often treat neural populations as pools of identical and interchangeable elements. Here, Dahmen et al. highlight recent theoretical advances that reveal the imp...

At the Bernstein Conference 2024, Jeremie Lefebvre and I organized a workshop on the computational consequences of neural heterogeneity. Now, slightly more than a year later, we funneled the emerging discussions into a perspective piece: www.cell.com/neuron/fullt...

Greetings from Kyiv,
where the night brought missiles and drones.
Explosions still continue this morning.

Emergency power outages.
Heating problems.
Residential buildings hit.

Christmas Procession in Kyiv.

I want the world to see this.

anyone got any advice on the following situation? I wrote and did a big chunk of the admin for a large MRC grant which also also awarded. I am named in the Staff breakdown on the grant as "researcher co-lead" with 100%FTE, and I am mentioned by name as "postdoctoral researcher Maria Niedernhuber"

The Tasselled Wobbegong is a master of disguise that can eat a fish almost as big as itself in one gulp. It's classified as a shark, but when it lays on the sea floor it looks like a harmless rug if you manage to see it. But with powerful jaws and sharp teeth they are no fish to mess with.

This is a scandal.

Public universities should be banned from paying these insane buyouts for college coaches.

No pro sports teams are paying $33 million to fire their incompetent coach, so why are colleges paying this kind of money?!?

And I swear, once again, this is not dunking on kids. We are seeing this at all levels--even grad students. AI + social media has had a profound impact on how we think and process our world, and we can't stop to reflect on it, because billionaires keep hurling addictive tech at us.

Neural dynamics outside task-coding dimensions drive decision trajectories through transient amplification Most behaviors involve neural dynamics in high-dimensional activity spaces. A common approach is to extract dimensions that capture task-related variability, such as those separating stimuli or choice...

“Our findings challenge the conventional focus on low-dimensional coding subspaces as a sufficient framework for understanding neural computations, demonstrating that dimensions previously considered task-irrelevant and accounting for little variance can have a critical role in driving behavior.”

Tonight was a very bad night.

I want you to understand what it is like to live in Chicago during this time. Every day my phone buzzes. It is a neighborhood group: four people were kidnapped at the corner drugstore. A friend a mile away sends a Slack message: she was at the scene when masked men assaulted and abducted two people on the street. A plumber working on my pipes is distraught, and I find out that two of his employees were kidnapped that morning. A week later it happens again. An email arrives. Agents with guns have chased a teacher into the school where she works. They did not have a warrant. They dragged her away, ignoring her and her colleagues’ pleas to show proof of her documentation. That evening I stand a few feet from the parents of Rayito de Sol and listen to them describe, with anguish, how good Ms. Diana was to their children. What it is like to have strangers with guns traumatize your kids. For a teacher to hide a three-year-old child for fear they might be killed. How their relatives will no longer leave the house. I hear the pain and fury in their voices, and I wonder who will be next. Understand what it is to pray in Chicago.

“I want you to understand what it is like to live in Chicago during this time.”

Today, as the Fed cuts, is another good day to note how we’ve just totally normalized & moved on from the unprecedented violation of central bank independence that Stephen Miran represents. This would’ve been a huge scandal requiring his resignation from at least one post in any prior admin. Now? 🤪

The whole Third Term Project isn’t actually about Trump. The people behind it know he will likely be dead or enfeebled by 2029. It is about them, the vastly unpopular group around Trump, wanting to grift us forever without elections.
