The Preston Lab will be at @sfn.org #SfN2025! Come see what we've been working on 🧠
We'll discuss how kids & adults remember when things happen, how memory changes impact reasoning & how we learn different actions have different consequences based on the setting.
Find us Monday & Wednesday 🤘

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🧵
