Happy birthday to #neurologist Santiago Ramón y Cajal (1852 - 1934), here in front of Purkinje and granule cells from a pigeon, based on one of his own drawings! 🧪🐡 #histsci Cajal &Golgi won the Nobel in 1906, “in recognition of their work on the structure of the nervous system”. He was as much of 🧵

Vectorized instructive signals in cortical dendrites - Nature

Mice learning a neurofeedback brain–computer interface task show neuron-specific teaching signals in cortical dendrites, consistent with a vectorized solution for credit assignment in the brain.

I need hand-tracking in social VR for my research, but gestures just don't work well. I invented a solution. I call it #CyberFinger. We shipped first beta-dev units in late 2025. Now its 2026 and it's really satisfying to start to get community interest and feedback ... here's one of my favorites👇

We just introduced ResoniteLink - an open protocol for working with @resonite.com's data model! It's going to be building block for official Unity SDK, but (hopefully) also many community tools and integrations! store.steampowered.com/news/app/251... #Resonite #socialVR #gamedev

This CyberMonday, we are launching the #CyberFinger to creators and developers of the #Resonite community for a developer evaluation beta now at scicortex.com. Its a hands-free wearable VR controller for optical hand tracking that plays well with keyboards. www.youtube.com/watch?v=AIAD...

Check out our new paper! Vision models often struggle with learning both transformation-invariant and -equivariant representations at the same time. @hafezghm.bsky.social shows that self-supervised prediction with proper inductive biases achieves both simultaneously. (1/4) #MLSky #NeuroAI

Preprint Alert 🚀 Can we simultaneously learn transformation-invariant and transformation-equivariant representations with self-supervised learning? TL;DR Yes! This is possible via simple predictive learning & architectural inductive biases – without extra loss terms and predictors! 🧵 (1/10)

This is bleak reading

For understanding learning in neocortex 🧠, self-supervised learning 🤖 is interesting, but has several shortcomings. Seq-JEPA is a step in the right direction. It learns by predicting sensory outcomes from series of interactions. Cool things emerged! 👇with @shahabbakht.bsky.social #MLSky #NeuroAI
