🧠🌟🐭 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🧵

I, too, can become aggressive toward my pups (children) when hungry #hangrymom #cantgentleparentonanemptystomach
Researchers at the Crick found that virgin female mice can become aggressive towards pups when hungry, but only in certain hormonal states.
It highlights the importance of understanding hormones when observing how different physical states interact in the brain.

Anyone out there know of a good public benchmark/dataset for rodent vocalizations?
Something intended for benchmarking ML models (detection, classification, etc) would be ideal, eg like AnuraSet but mice/rats/etc 🐀🐀🐀

A nice, layperson writeup of my latest work, which is now out on eLife!
TLDR: Using snRNA-seq, we find cell type abundance differences and sex-biased gene expression differences that may explain innate differences in mating + parenting behavior

The parenting styles of deer mice
Single-nuclei RNA-sequencing sheds new light on how two closely related species of deer behave differently when mating and caring for young.

Hello, world! Always exciting to join a new platform early enough to actually get my name as my handle 💃
