New paper from my PhD out in @elife.bsky.social! 🎉 We asked: when the state of the world is changing, how does the brain adjust how much incoming evidence is accumulated? Turns out there isn't one answer—there are (at least) two. 🧵

🎯New preprint! The resource-rational dynamics of evidence accumulation www.biorxiv.org/content/10.6... Evidence accumulation isn’t stationary. It is dynamically controlled to trade off information gain against cognitive effort. With Jiang Mao, Tobias Donner @donnerlab.bsky.social, Alan Stocker

Cow Tools! We have lived alongside cows for nearly 10,000 years. We breed them and exploit them It is now, only now, that we have discovered THEY CAN USE TOOLS Here I describe our study (paper) www.sciencedirect.com/science/arti... in @currentbiology.bsky.social with @auersperga.bsky.social

Go, Catrina and high-gamma activity!

🚨 New preprint! Why do some insights from spikes translate to field potentials while others don't? In this paper we compare visual memory representations in spikes and LFPs to propose a general framework that answers this question. www.biorxiv.org/content/10.6... 🧵 (1/10) 🧠🟦 🧠💻

@weratedogs.com -- We completed our puzzle to find that important dog parts have been redistributed. Our soccer-prodigy corgi was given a bonus limb at the cost of a friend's snoot. Athleticism unmatched. Anatomy concerning. We hoped for one of each piece, but everyone is still perfect. 13.5/10

With all the fuss over tylenol, we're missing a bigger issue: we don't know enough about medication safety in pregnancy because so few drug studies include pregnant people. And that harms both women and their fetuses. My latest @sciam.bsky.social www.scientificamerican.com/article/what...

There's a Dangerous Gap in Drug Research in Pregnancy

Less than 1 percent of clinical trials include pregnant or breastfeeding people. Experts say that needs to change
