What's the mechanism? Dendrites. PCA of dendritic voltages shows that harder tasks recruit higher-dimensional dynamics, more semi-independent dendritic branches doing local computations. It's a distributed, high-rank representation across the tree. (9/15)

NEW PAPER🚨👀 in Science Advances with a wonderful transatlantic team. (incl @sylvainbaillet.bsky.social @olejensen.bsky.social @katduecker.bsky.social) Using human MEG, we found lower-order and higher-order neural processes that underlie illusory transitions in conscious visual perception. 🧵👇

Hierarchical brain dynamics supporting visual perceptual transitions

Illusory transitions in conscious visual perception involve both early visual cortex and higher-order motor cortices.

Almost done with my next lecture, so going back now to work on some new memes

The biggest problem holding neuroscience back right now isn’t data or tools, thanks in large part to the BRAIN Initiative. It’s fragmentation across species. I wrote this to hopefully spark discussion around an issue that can only be solved as a community👇 www.thetransmitter.org/animal-model...

Neuroscience has a species problem

If neuroscience is serious about building general principles of brain function, cross-species dialogue must become a core organizing principle.

🚨 New preprint! Why do some insights from spikes translate to field potentials while others don't? In this paper we compare visual memory representations in spikes and LFPs to propose a general framework that answers this question. www.biorxiv.org/content/10.6... 🧵 (1/10) 🧠🟦 🧠💻

Neural representations of visual memory in inferotemporal cortex reveal a generalizable framework for translating between spikes and field potentials
