🚨New preprint alert! The thalamus has long been seen as a relay of sensory signals to cortex. But could it also generate its own structured activity? Our study explores this question in the head-direction (HD) system. Some explanation 🧵👇 1/13

Coherent dynamics of thalamic head-direction neurons irrespective of input
While the thalamus is known to relay and modulate sensory signals to the cortex, whether it also participates in active computation and intrinsic signal generation remains unresolved. The anterodorsal...

For those interested in open neuroscience learning tools, check out the preprint for “RetINaBox: A hands-on tool for experimental neuroscience" that a couple students in my lab worked on in collaboration with the Trenholm lab:

Such a fun collaboration to be a part of! Turns out, like many things in the brain, inhibition-stabilization is the answer. 👀🧭⚖️

This was a real testament to just how fun and fruitful a collaborative project can be. Thank you Emilie, Dom, and Stuart for inviting us in! Hope you enjoy reading it as much as I enjoyed working on it!

Ok is this a LinkedIn kind of social media platform, or a pre-Musk Twitter kind of social media platform?

Stoked to see this paper finally out! It answers two big questions: where visual objects are encoded in the brain, and how head-direction cells get oriented using visual landmarks. Super fun collaboration with
@mace-lab.bsky.social
and Stuart Trenholm.

Thrilled to share that our work is now published in Science! ✨ We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭
