Persistent Decision-Making in Mice, Monkeys, and Humans

This study compares persistence in decision-making across mice, monkeys, and humans in a dynamic task, finding that primates outlast mice in exploitation strategies.

Dopamine and norepinephrine differentially mediate the exploration-exploitation tradeoff

This study investigates how dopamine and norepinephrine differentially influence exploration-exploitation tradeoff in mice using pharmacological manipulations and behavioral tasks.

Hierarchical organization of rhesus macaque behavior

This study identifies hierarchical organization in rhesus macaque behavior through automated posture analysis using 3D motion tracking data.

Sex differences in learning from exploration

This study identifies sex differences in exploration patterns during value-based decision making in mice, showing males explore more but get stuck, while females explore less but learn faster.

Divergent strategies for learning in males and females

The paper finds that female and male mice use different strategies to learn value-based decisions in a two-armed bandit task, with females learning faster and using a more constrained approach.
