🎉 "High-dimensional neuronal activity from low-dimensional latent dynamics: a solvable model" will be presented as an oral at #NeurIPS2025 🎉
Feeling very grateful that reviewers and chairs appreciated concise mathematical explanations, in this age of big models.

Some neurons respond more strongly to visual stimuli than others. But the rest of the brain doesn’t prioritize signals from those neurons, according to a new study. Read more in this month’s Null and Noteworthy.

Null and Noteworthy: Downstream brain areas read visual cortex signals en masse in mice
The finding contradicts a theory that the regions prioritize neurons that are adept at identifying specific stimuli. Plus, a response to a study that questioned immune memory in astrocytes.

Introducing our new favorite stimulus. A few minutes are enough to map the visual preferences of thousands of neurons.

Brainwide blood volume reflects opposing neural populations
Brainwide fluctuations in blood volume arise from two populations with opposite relation to brain state and distinct relationships to blood supply

Our new preprint 👀
The firing of neural populations is high-dim even if their subthreshold activity is low-dim! This work by @bio-emergent.bsky.social and @haydari.bsky.social shows how, with a solvable model, a data analysis technique, and data from mouse visual cortex: www.biorxiv.org/content/10.1...
High-dimensional neuronal activity from low-dimensional latent dynamics: a solvable model
Computation in recurrent networks of neurons has been hypothesized to occur at the level of low-dimensional latent dynamics, both in artificial systems and in the brain. This hypothesis seems at odds ...

Excited to share my PhD paper! In it, we use targeted 2-photon optogenetic stimulation to determine how V1 activity is read-out in a detection task. We found that network influence, not visual coding properties, predicted the impact of ensembles on behavior - contradicting our expectations (1/5).

If you do multi-plane 2p imaging, you may see the same cells across planes. We built Suite3D exactly for this purpose! It removes duplicates, corrects axial movement, finds more cells with less noise, much faster than alternatives.
