How does the retina distinguish an object moving through the world from the world moving around us? In work led by Pratyush Ramakrishna (w. Josh Morgan), we discover motion-coherence selectivity—and show how single-cell and population geometry create it. https://t.co/7LkrdtFWG9

Delighted to see our latest test of Active Space-Time Visual Encoding published!

Saccades do more than select where we look: their amplitude also helps determine what information we extract from a scene, as predicted by the transients they generate.

Very excited that our paper is now out at @arxiv🎉

As a neuroscientist🧠, I wand to understand how (single) neurons encode the visual world. But how to do this in an automated yet interpretable way when we record thousands of neurons to complex natural stimuli?

Here, we use vision language models, specifically @GeminiApp, to convert neural selectivity in monkey visual cortex into language, i.e. a semantic hypothesis, which we verify with text-to-image generation!

Every experimental neuroscientist knows the feeling: you have a hypothesis, but running the experiment takes months👩‍🔬

In our new preprint @biorxiv_neursci , we present an openly available functional ''digital twin'' of the retinal input to the mouse superior colliculus that lets you test hypotheses in the model first — try it out yourself using the link below 🧠

We combined chronic two-photon imaging of >200k retinal ganglion cell axonal boutons in the mouse superior colliculus (SC) with deep dynamic models that predict neural responses to parametric light stimuli and natural movies.

Key findings⚡️

▸ Retinal inputs to the SC form functionally distinct, laminar-organized response types, identified via Gaussian mixture model clustering

▸ The functional diversity of retinal output matches that of retinal input to the SC. We show this by aligning our dataset with a retinal reference dataset using a variational autoencoder with adversarial training

▸ Our deep dynamic digital twin learns stimulus–response transformations and generalizes to stimuli it was never trained on, including parametric stimuli used for cell type identification

The model functions as a virtual lab bench: feed in any stimulus you're curious about and generate predicted neural responses. As a proof of concept, we fed in a looming stimulus — known to trigger defensive behavior in mice — and identified putative response types selective for this stimulus

Try it in our Colab notebook with your own stimulus and see what the model predicts

New paper out in @NeuroCellPress 🎉

What determines contextual modulation in primary visual cortex (V1)?

The key result ⚡ V1 neurons are facilitated by surrounds that complete their optimal center feature according to natural scene statistics, and suppressed by surrounds that disrupt it — a principle explained by hierarchical Bayesian inference and conserved across mouse and macaque.

These results converge with Deveau et al. in @NeuroCellPress (https://t.co/THpNjjVuvT) from the lab of @HistedLab, who show that recurrent circuits in V1 filter temporal input sequences to selectively boost natural dynamics, and Lange et al. in @ScienceMagazine (https://t.co/j8EW7SnGUO) from the lab of @haefnerlab, who show that perceptual learning increases population redundancy as predicted by generative inference. A consistent picture is emerging: (early) visual cortex actively infers the statistical structure of the natural world.

Amazing collaboration with @AToliasLab @haefnerlab @sinzlab Antolik Lab & many more — led by @jiakunfu, with co-authors @suhas_shrinivas & @LuchinoBaroni & many more

The paper is open-access and available here: https://t.co/d1tg4MPFlm

More detailed approach:

We trained CNN digital twins on large-scale two-photon recordings from mouse V1 and used them to synthesize, for each neuron individually, the surrounds that most strongly facilitate or suppress its response to its optimal center stimulus. Closed-loop in vivo inception loop experiments confirmed the predictions.

Key qualitative finding:
Surrounds that complete the optimal center feature under natural scene statistics → facilitation
Surrounds that disrupt it → suppression

We verified this with an independent generative diffusion model (blind to our CNN): statistically likely continuations of the optimal center feature were significantly more similar to facilitatory surrounds in V1 representational space. The same principle holds in macaque V1 despite major differences in receptive field organization.

We formalize these results in a hierarchical Bayesian inference model — V1 neurons represent posterior beliefs about local features, with feedback from higher areas encoding global scene structure — and find like-to-like excitatory connectivity in the MICrONS dataset as a candidate circuit mechanism.
