Out today in @nature.com: we show that individual neurons have diverse tuning to a decision variable computed by the entire population, revealing a unifying geometric principle for the encoding of sensory and dynamic cognitive variables.

Convergence of efficient and predictive coding in multimodal sensory processing The existence of pathways connecting different sensory modalities in the brain challenges the traditional view of sensory systems as operating independently. However, the reasons and mechanisms underl...

I developed a normative coding theory for feedback-modulated canonical networks, providing a unified view of (1) efficient & predictive coding, (2) computational & algorithmic principles, (3) unimodal & multimodal sensory processing.

Remember what your partner said during a heated argument? Or the rush of getting your first job offer? Why do these emotionally arousing moments stick? Across 3 studies, and 3 arousal measures, we found that emotional arousal enhances memory encoding by promoting functional integration in the 🧠 1/🧵

It is obvious we are using causal inference to understand narratives (with aha moments). But how does the brain work for this? This is a cool paper!!

Congrats @hayoungsong.bsky.social

Would recording all neurons reveal their interactions? For years, I was captivated by the idea that if we could record the activity of every neuron in the brain, we’d eventually crack the code…

If we could record all neurons we still would not know how they communicate: medium.com/@kording/628...

Hi Bluesky!

Happy to share my PhD work:

Spatial information was consistently represented across tasks in a low-dimensional subspace of PFC activity, while task identity was encoded in an orthogonal subspace, providing a stable and independent representation of context.
