This report in Nature on the costs of competing for & administering scientific grants is shocking: "In other words, European taxpayers will have spent more on the funding process than on the funding itself, and the scientific ecosystem has been drained." www.nature.com/articles/d41... 🧪

SAVE THE DATE! On June 16-17, 2026, the NEST Initiative is excited to invite everyone interested in Neural Simulation Technology and the NEST Simulator to the NEST virtual Conference 2026. Registration and abstract submission will open soon! nest-simulator.org/conference

0/10 Thanks for the interest in our preprint. Some takes say it negates or fully supports the “manifold hypothesis”, neither quite right. Our results show that if you only focus on the manifold capturing most of task-related variance, you could miss important dynamics that actually drive behavior.

Y’all are reading this paper in the wrong way. We love to trash dominant hypothesis, but we need to look for evidence against the manifold hypothesis elsewhere: This elegant work doesn't show neural dynamics are high D, nor that we should stop using PCA It’s quite the opposite! (thread)

A study led by Cina Aghamohammadi is now out in ‪@natcomms.nature.com‬! We developed a mathematical framework for partitioning spiking variability, which revealed that spiking irregularity is nearly invariant for each neuron and decreases along the cortical hierarchy. www.nature.com/articles/s41...

Undecided which workshop to attend at #BernsteinConference ? We put together a stellar lineup for a satellite workshop on the effects of top-down signals on neuronal dynamics! 🧠✨📣 Join us tomorrow in room 0.101 ! bernstein-network.de/bernstein-co... With @ackurth.bsky.social

On the first workshop talk (Monday), I'll make the case that everything might be everywhere when you decode, but that is not the end of the story: different regions have very different dynamics and encoding geometries. This workshop is organized by @aitormg.bsky.social and @ackurth.bsky.social

Our current approach to defining neural populations is largely arbitrary. We need new methods for grouping cells, ideally by their dynamics, writes @markdhumphries.bsky.social #neuroskyence www.thetransmitter.org/systems-neur...

1/3) This may be a very important paper, it suggests that there are no prediction error encoding neurons in sensory areas of cortex: www.biorxiv.org/content/10.1... I personally am a big fan of the idea that cortical regions (allo and neo) are doing sequence prediction. But... 🧠📈 🧪
