Shared Latent Decision Strategies Underlie Reward-Guided Behavior Across Species

This study identifies a shared latent reward-learning strategy in mice and humans using probabilistic reversal learning tasks and latent state modeling.

Sex-specific exploration accounts for differences in valence learning in male and female mice

This study shows that sex differences in valence learning in mice are due to baseline exploratory behavior rather than inherent learning differences, highlighting the importance of mixed-valence paradigms.

Reward integration in prefrontal-cortical and ventral-hippocampal nucleus accumbens inputs cooperatively modulates engagement

The paper identifies a common neural motif in prefrontal-cortical and ventral-hippocampal inputs to nucleus accumbens that integrates reward history and shows how these inputs co-operatively modulate task engagement.
