Recurrent cortical networks encode natural sensory statistics via sequence filtering The visual cortex receives a stream of high-dimensional sensory input. The role of dense local, recurrent cortical connections in shaping responses to these inputs has been unclear. Here, we show that...

Excited to share our new paper to be published in Neuron!

With Valentin Schmutz @bio-emergent.bsky.social and Wulfram Gerstner @gerstnerlab.bsky.social, we explore how circuit structure in RNNs shapes network computation and single-neuron responses.

Finally getting on top of new papers and god there are so many good ones. This from Lykken, Kanter, @edvardmoser.bsky.social & @m-bmoser.bsky.social is brilliant. Neuropixels showing differential phase shifts across grid modules drive place cell remapping. Elegant grid-to-place transformation story.

Compact deep neural network models of the visual cortex - Nature Parsimonious deep neural network models can be used for prediction of visual neuron responses.

Neurons around a recording ephys electrode

Diagram of monkey looking at a screen in a neuroscience experiment

Spike rasters for two units in response to a checkerboard shown in the screen. One is an ON neuron, the other is an OFF neuron

Waveforms of single neurons within a single ephys electrode sorted using K-means clustering.

Just uploaded some of my *hand-crafted* comp-neuro teaching materials, thought they might be useful to someone out there.

I actually couldn't believe it was JUST seven years ago, feels like I've been doing these implants all my life 😅

Just found this image of a DOWN state in posterior parietal cortex I recorded 7 years ago with my first linear probe, I distinctly remember I couldn't believe my own eyes 😵‍💫

Why You Can’t Remember Being a Toddler This form of amnesia is almost universal, but has long been overlooked.

Why can't you remember being a toddler? Or can you?

Brain Mapping: Redefining borders in the sensorimotor cortex

Place cells in CA1 lack topographical organization of firing locations | PNAS Topography is a well-described and well-known concept for cortical organization in primary sensory and motor cortices of mammalian brains. Similar ...

A half-century old question may have its final answer. Using high-resolution #Mini2P microscopes, we find no evidence of local topography in #PlaceCells. Place fields of neighbouring cells are no more similar than those of randomly selected cells. 🧠🗺️ Out now in @pnas.org www.pnas.org/doi/10.1073/...
