Want to explore connectivity & projection patterns yourself, like we do here? We released brain_street_view to let you pick any injection site in the Allen Connectivity Atlas and visualize where it projects in your favorite region of interest: github.com/Julie-Fabre/brain_street_view
New method for identifying the fine transcriptomic types of thousands of neurons recorded in vivo!
New preprint, on a very different topic: a mathematical theory of evolution for self-designing AI.
AI is increasingly designed by AI. What systems might emerge after generations of self-designing AIs competing for computing resources? ↓

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states!

Losing one side of Superior Colliculus is bad, but losing both sides seems fine. Wait, what?
Flora & team discovered why: both sides press for contra actions and against inaction, obeying an incredibly simple additive rule.

Excited to share a new review by @kocherlab.bsky.social and me:
Nature-inspired neuroscience
We discuss diverse sensory systems and behaviors across the animal kingdom and argue for their integration into neuroscience. New tools in diverse systems are making this possible ✨

As artificial intelligence systems (AIs) become increasingly produced by recursive self-improvement, a form of evolution may emerge, with the traits of AI systems shaped by the success of earlier AIs ...

How do the basal ganglia turn what you see into what you do?
New preprint w/ @kenneth-harris.bsky.social, @flickerfusion.bsky.social & @carandinilab.net: we recorded across striatum, GPe & SNr in a Go/NoGo task. Striatum encodes which stimulus, GPe & SNr encode action. 🧵
