Neural representations of tasks change over time, even in the absence of changes in task performance. But neurons change tuning at different rates. How does a neuron's stability relate to its interactions with the population?

Writing forces your brain to coordinate memory, reasoning, and meaning-making simultaneously. Every time you write, you rewire toward clearer thinking. Every time you let an LLM do it, you rewire toward consumption.

Cosyne invited me to give a long tutorial (4 hours!) on methods to quantify differences high-d neural recordings across animals, brain regions, deep neural nets, etc. The recording is up on youtube. I hope it inspires more research on this fundamental topic!

โชEver wondered how GABAergic interneurons shape cognition? The IN-CODE consortium's latest NeuroView article introduces a "population approach", shifting the focus from individual interneurons to cooperative networks. Dive into the future of interneuron research here:

The 6x US memory champion โ Nelson Dellis โ can memorize a deck of cards in 40 seconds and knows the first 10K digits of pi. To figure out how, he let us peak inside his brain. Here is what we learned in our precision brain mapping study

I tracked every keyword in 22 years of Cosyne abstracts to map how computational neuroscience evolved โ from Bayesian brains to neural manifolds to LLMs โ and where it's heading next.

Kristine's paper "Information theoretic measures of neural and behavioural coupling predict representational drift" is now available on PLOS Comp. Biology. Link:
doi.org/10.1371/jour...
This work was led by Kristine (former PhD student) while visiting University of Cambridge during her PhD.
