- Reposted by Julien CorboCongratulations to @juliencorbo.bsky.social and all the co-authors for this amazing study! 🎉🏅🤯. Don’t miss Julien’s thread 🧵 👇🏻 that summarizes very well the main points of the paper.
- New paper out! 🚨 📰 With @batuhanerkat.bsky.social, John McClure, @hussainyk1.bsky.social, @polacklab.bsky.social we reveal how discretized representations in V1 predict suboptimal orientation discrimination. 🧪🧠🐭 This work reconciles neuro and psychometric curves www.nature.com/articles/s41...
- Through task training, V1 transitions from continuous to categorical representations that predict the 🐭 behavioral performance. Task-driven excitability modulation splits the evoked activity into discrete domains, suggests a probabilistic encoding of the stimuli category (Go/NoGo). More details in 🧵
- Behavioral thresholds vs. neuronal capacity: Mice trained in a Go/NoGo orientation task showed discrimination threshold between 15°–30°. But V1's neural activity contained more information; shallow neural nets trained on V1 data vastly outperformed behavior ➡️ at 20° angle, SNN D'>4, Mouse D'< 1.7

- Reposted by Julien CorboThe wonders of population coding! Recent paper by @juliencorbo.bsky.social et al. @polacklab.bsky.social -> visual cortex in trained mice encodes orientation differently from in naive mice... almost more "messily"(?)... but behavior is good. #neuroskyence #matlab 🧪 🧠 doi.org/10.1038/s414...
