We use game theoretic tasks, cross species comparisons, modelling strategies, and mesoscale imaging to reveal a cortical mechanism for unpredictable choices.doi.org 1356
Chunyu Ann Duan @annduan.bsky.social · 08/06/2026Another fun lab retreat with this amazing group of people! This year we went to Isle of Wight and spent 2 days over bbq, pub quiz, board games, and more science. My favorite part is that we paired people from different projects together and had idea smash up sessions. Highly recommend! 1160

With an eye to keeping science at its most rigorous, they cross the line into criticism that's too harsh. They are the ones who risk killing your scientific spirit. They are reviewer 2. /1 77219

Somewhat surprisingly, our monkeys’ choices satisfied IIA (independence of irrelevant alternatives). In OFC, decision variables were represented in the same way under trinary and under binary choices. This property implies IIA. www.biorxiv.org/content/10.1...biorxiv.orgNeuronal Activity in Orbitofrontal Cortex during Trinary Choices under RiskEconomic choice entails computing and comparing the subjective values of different goods. Orbitofrontal cortex (OFC) is thought to contribute to both operations. However, previous work focused almost ... 1154
