My main postdoc work is now published: www.nature.com/articles/s41...! We (myself, Isabel Low, Frances Cho, and @lgiocomo.bsky.social) discovered task-relevant remote representations in entorhinal cortex independent of CA1. #paperthread below! 1/13

Brilliant work on the development of grid cells by Matteo et al!

1/N: Dear cognitive map fans, I’d like to share a model I’ve been working on for a while (clearing backlog :). I show how a vector navigation architecture (VNA) and a “positional inference network” (PIN) can build Universal Cognitive Maps (UCMs) for abstract spaces.

Fantastic opportunity to do pioneering single-unit recordings from the HUMAN hippocampus and other parts of the brain, with @jorgen-sugar.bsky.social at @uio.no, Norway.

Is there micro-scale spatial topography in the hippocampus?

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

Happy belated publication of some of my PhD work!

Building on our findings that grid field firing rate changes can cause hippocampal remapping and memory impairment, here we show that this effect has a fixed input-output relationship, and we can even predict how place cells will remap!

Have you ever wondered how the brain should represent the sensory world in order to generate behavior? Read our new preprint: work by Shuhong Huang shuhonghuang.bsky.social with our long-standing collaborator James Fitzgerald at Northwestern.

New paper alert! 🚨

We found that the brain's compass is remarkably stable at two scales

1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit

This may be key to how the brain aligns its other maps.

Thanks! Our hunch is that parasubiculum converts these egocentric vectors to allocentric ones by adding allo HD and ego "attention" signals, perhaps similar to how flies do it (eg Hulse 2021, Lyu 2022, Lu 2022).

By adjusting the direction, width and frequency sweeps, the sweep system may provide a mechanism for allocating spatial attention in allocentric hippocampal maps. Check out the preprint for more findings and videos!

www.biorxiv.org/content/10.6...

We had a lot of fun doing these experiments! Theta sweeps in MEC and internal direction signals in parasubiculum track moving objects during pursuit and reverse during backward movement. Simultaneously recorded HD cells in other areas remain locked to head direction across behaviors:

Such an elegant study, congratulations to all of you!

I’m excited to share my first PhD preprint!🎉
We studied how interactions between medial entorhinal cortex (MEC) and hippocampus shape theta sequences during navigation, and asked whether some “planning-like” patterns in hippocampus could arise from upstream MEC dynamics. (1/8)

Wow, congrats Flavio!!

Congrats, Adrian!

How can the brain create countless unique memories using a single, universal metric of space? We’ve been waiting for the answer to this for two decades!

Your brain doesn’t just passively track time ⏳ - it structures it.
In @Science.org we show that activity in 🧠 memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2)

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.

We identify a hypothalamic-brainstem circuit linking internal states to locomotion: These projections drive safety-focused movement over competing behavior.
