🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!

We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

🚨new paper: the head-direction circuit as a model of primary thalamocortical system. Check this out 👇

kudos to @adrian-du.bsky.social for the huge amount of work put into this opinion piece, starting with the beautiful figures comparing the different thalamocortical systems 🤩
Really excited to share this Opinion piece we've been working on with fellow head-direction cell geeks @apeyrache.bsky.social @desdemonafricker.bsky.social and (bsky-less?) Andrea Burgalossi! While head-direction cells pop up in many cortical regions, we think that one of them is quite unique (1/8)
The postsubiculum as a head-direction cortex
The organisation of thalamocortical networks follows a conserved structure. Traditionally, these are divided into primary sensory systems that receive…

How does genetic and molecular variation, either through evolution or within a species, result in neural and behavioral variation? How many different ways can you evolve a similar behavior?

The brain is incredibly densely connected. Human cerebral cortex may have as many as *one trillion* connections.

Most of those cortical connections are recurrent, inside each area. What do they do?

New preprint! What happens if you add neuromodulation to spiking neural networks and let them go wild with it? TLDR: it can improve performance especially in challenging sensory processing tasks. Explainer thread below. 🤖🧠🧪 www.biorxiv.org/content/10.1...
Neuromodulation enhances dynamic sensory processing in spiking neural network models
Neuromodulators allow circuits to dynamically change their biophysical properties in a context-sensitive way. In addition to their role in learning, neuromodulators have been suggested to play a role ...

How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

I am very happy to share our work with
@fredcrevecoeur.bsky.social

Here, we move away from the complexity of training a neural network and ask - what minimal ingredients produce motor‑cortex-style dynamics?

Does your research involve comparing experimental conditions? Then our latest publication is for you: We developed generalized contrastive PCA (gcPCA), a tool for comparing high-dimensional datasets. 🧠📊 doi.org/10.1371/journal.pcbi.1012747
This tool was born out of necessity, here is the story. 🧵

Confused by all the talk abot NIH indirect grant rates? Today's blog is an explainer.

tl;dr: the actual amount of $ at stake right now is not that large, but bigger picture is the symbolism of a sector largely at the mercy of a malevolent central government.
