This 2017 preprint by @suryaganguli.bsky.social is foundational: the dimension of a neural code can't be > that of the experiment used to measure it. Yet it is not very widely known. Maybe because people don't like the message? And because it's "unpublished"? (After writing it, Gao left for SpaceX)
Low-dimensional activity for simple tasks is a clear prediction from basic coding arguments
A theory of multineuronal dimensionality, dynamics and measurement
In many experiments, neuroscientists tightly control behavior, record many trials, and obtain trial-averaged firing rates from hundreds of neurons in circuits containing billions of behaviorally relev...

We will have a thread and a party when the paper comes out! In the meantime the updated preprint is greatly improved over previous versions thanks to constructive feedback from reviewers!
Re: recent studies about neural coding being high-dimensional, and I thought I'd contribute our recent preprint: www.researchsquare.com/article/rs-1...
@eliezyer.bsky.social and I will do a full thread on this when the paper comes out, but his work shows it's (as usual) a little more complicated 🧵

I'm happy to share that I've recently started a postdoctoral position in the Priya Rajasethupathy Lab at Rockefeller University!
I'm excited for this new chapter where I'll continue exploring brain intrinsic activity and the rules that govern cognition, now diving deeper into molecular approaches.

Stoked to see this paper finally out!
It answers two big questions: where visual objects are encoded in the brain, and how head-direction cells get oriented using visual landmarks.
Super fun collaboration with @mace-lab.bsky.social and Stuart Trenholm.

We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭

Gero's talk at the last SFN about this has been the most mind-blowing seminar in neuroscience I've seen.
Sleep might be an “inescapable consequence” of aerobic metabolism, new findings in fruit flies suggest.

Mitochondria set ‘ancient’ metabolic thermostat for sleep in flies, separate from circadian rhythms
During waking hours, a specialized set of sleep neurons in the fly brain accumulates reactive oxygen species, which eventually trigger sleep to clean up and repair the damage they do.

I previously noticed that to decode body movements from V1 superficial layers required much more neurons (>600) than my recordings of deep layers (~200). It's great to see a head-to-head comparison
A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently.
Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries.
