Very cool! Thanks Peter!

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/...

My first first-author paper is on bioRxiv! Here we ask whether the same subset of neurons in ACC always display object correlates during extensive familiarisation to 2 objects. A short 🧵1/10

Do you love quantifying animal behavior as much as we do? We have just the tool for you! Presenting #OCTRON - a pipeline that helps you create rich annotation data and enables training of custom segmentation models. Have a look, particularly if you work with non-model / invertebrate organisms!

In Vivo Analysis of Medial Perforant Path-Evoked Excitation and Inhibition in Dentate Granule Cells Across brain regions and species, the dynamics and balance of excitation and inhibition critically determine neuronal firing. The hippocampal dentate gyrus is a brain area thought to be strongly regul...

Thrilled that the last bit of my PhD work (and my original PhD project) finally found its way to the light:

For them lovers of dentate gyrus. We quantify the excitatory and inhibitory responses of granule cells to distinct inputs from the medial perforant path.

Still at SfN on the last day? During the morning session on the 19th, 8:00AM - 12:00PM, come check out our posters from the Moser, Zong, and Gonzalo Cogno groups in row QQ ('Grid cells and spatially modulated cells'). Ephys, imaging, remapping, development, sweeps and more! 🧠
Detailed thread below 👇

QQ2: Where are the grid cells and if so, how many? We find that grid cells form a discrete "hot spot" segregated from other functional cell types in the superficial layers of MEC and PaS. @martipof.bsky.social

Our new paper out now in Science explores how neural activity in the lateral entorhinal cortex (LEC) *drifts* over time - and *jumps* at key boundaries - to help organize events in memory.
