On 3 June at 11 am/5 pm CEST I am organizing a webinar for (soon-to-be) postdocs in computational neuroscience. Get to know my work and meet my group if you are looking for a postdoc position! Register at events.hifis.net/event/2649/ (11 am) or events.hifis.net/event/2674/ (5 pm).

In this new study we show that cortical resting-state activity is hierarchically organized 🧠 Cool work by @aitormg.bsky.social

Assessing the Similarity of Real Matrices with Arbitrary Shape Singular Angle Similarity measures the similarity of real, arbitrary matrices by taking into account their two-dimensional structure, outperforming standard methods like cosine similarity or Frobenius...

If you need to compare matrices or two-dimensional data that can be brought into matrix form, consider using Singular Angle Similarity: journals.aps.org/prxlife/abst...

The NEST virtual conference is gearing up! Join us June 17-18, 2025 for a chance to exchange ideas and learn about developments in simulation science! Interested in contributing? The abstract submission deadline has been extended to **April 30**. Visit nest-simulator.org/conference. #nestsim

BREAKING:

We are suing the Trump admin on behalf of our members for unlawfully cutting off $400 million in federal funding for crucial public health research to force Columbia University to surrender its academic independence.

Stay Tuned.

DAY 6: Advent of Comp Neuro 🎄🤖🧠🧪

This nifty theory predicts how intrinsic timescales depend on network structure, neuron properties and input. A nontrivial task!

You might add NEST and its GUI tool NEST Desktop under the header of simulators. These are for simulations of point or few-compartment neuron networks. Various example models and tutorials exist.

If you are interested in neural manifolds, dimensionality, brain states, and/or top-down modulation you are gonna like this one! 🧠🙈💫🧪

Modeling neuron-astrocyte interactions in neural networks using distributed simulation Astrocytes engage in local interactions with neurons, synapses, other glial cell types, and the vasculature through intricate cellular and molecular processes, playing an important role in brain infor...

It is now possible to model neuron-astrocyte interactions using the NEST simulator. Check out our latest preprint: www.biorxiv.org/content/10.1...

Wow, so many new followers! Is there a huge X-odus going on?

Academics say flying to meetings harms the climate — but they carry on A survey at one of the biggest UK research universities finds that staff often end up flying to meetings despite a preference to avoid air travel. A survey at one of the biggest UK research universiti...

How do we fix academia's air travel problem?

I've been declining invites in order to avoid flying and it feels weird at first but in my experience, organizers are very understanding and many will allow a virtual presentation.

Daily oscillations of neuronal membrane capacitance Severin et al. describe time-of-day changes in membrane capacitance in excitatory neurons from the visual cortex and hippocampus. Membrane capacitance is usually stable. These daily variations could p...

This randomly popped up in my feed, and I've got to share it since it's just such a "never even thought about this" kind of paper: www.cell.com/cell-reports...

Neuron membrane capacitance oscillates wildly during the day?! 🧪🧠

Eating less beef is a climate solution. Here's why that's hard for some American men Climate researchers have long grappled with how to get Americans to eat less beef, a food with a huge global warming impact. Now some are thinking about it through the lens of gender.

Fellow dudes.

We eat a lot of beef.

Eating less beef and more of nearly anything else would greatly reduce the climate impacts of our food choices.

And we can still be manly men.

That's what Erdoğan's been doing in Turkey. I definitely do not recommend. It's heartbreaking watch everything that's been happening at my alma mater in recent years. Academically unqualified, state appointed bureaucrats gradually replacing admin and faculty ranks; faculty getting purged...

Episode #18 in #TheoreticalNeurosciencePodcast: On electric brain signals – solo episode

theoreticalneuroscience.no/thn18

Electric brain signals (spikes, LFP, ECoG, EEG) are typically modeled statistically. But biophysical forward modeling starting with neurons is an alternative.

If you're new to Bluesky, you should know that since there's no algorithm the Like button is exclusively for *you.*

It doesn't help a post move or spread.

If you want to help spread people's work (especially creators whose work you enjoy) YOU HAVE TO RESKEET.

What's with the Bluesky algorithm? Despite having indicated about 30 times that I'm not interested in posts of people saying they're supposed to write a manuscript or are writing or editing a book, or asking for book suggestions, this is the main kind of post it keeps feeding me.

How very 1984

How I hope that this platform really takes off so X and thereby Elon Musk loses influence

Projection much?
