A year ago these things could just shuffle along slowly and would fall down if you looked at them wrong

Message for participants of the #SNUFA 2025 spiking neural network workshop. We got almost 60 awesome abstract submissions, and we'd now like your help to select which ones should be offered talks. Follow the "abstract voting" link at snufa.net/2025/ to take part. It should take <15m. Thanks! ❤️

🚨 New preprint!
“A Computational Perspective on the No-Strong-Loops Principle in Brain Networks”
www.biorxiv.org/content/10.1...

Over the past 3 years, we’ve been investigating why cortical networks avoid strong reciprocal loops — and what this means for computation.

Costs: €100 for members of DGPA and bioDGPS, €150 for members of DGPA or bioDGPS, €200 for non-members.

🚨 Excited to share the latest preprint form the lab ➡️https://tinyurl.com/32d3be9f

Here we tackle a long-standing chicken-or-egg 🐣🥚question in #autism and developmental neuroscience

➡️ Is excitation–inhibition (E:I) imbalance a "cause" or a "consequence" of #autism?

Large-scale maps of altered cortical dynamics in early-stage psychosis are related to GABAergic and glutamatergic neurotransmission Cortex-wide changes in neural dynamics in early-stage psychosis relate to GABA-A or NMDA receptors and clinical symptoms.

I think Altman assumes that “PhD-level expert” means someone who speaks confidently on everything as opposed to saying “it’s nuanced,” losing their keys, and getting maniacally fixated on their current topic to the point of seeing it in everything.

Spiking neural networks people, this message is for you!

The annual SNUFA workshop is now open for abstract submission (deadline Sept 26) and (free) registration. This year's speakers include Elisabetta Chicca, Jason Eshraghian, Tomoki Fukai, Chengcheng Huang, and... you?

Thanks to Maryada (@giacomoi.bsky.social lab)! Due to component variability it is hard to set the weights across neuromorphic devices. Using our crosshomeostatic learning rule, that governs all four weight classes, we drove neuromorphic RNNs into balanced E/I regimes.
