Posterior parietal cortex mediates rarity-induced decision bias and learning under uncertainty

2024-10-26

Abstract excerpt

<h4>Summary</h4> Optimal decision-making under uncertainty is critical for survival, yet real-world decisions often deviate from optimality. Here, we report a rarity-induced bias in humans and mice, where rare events exert a stronger and more persistent impact on future decisions than common events. Optogenetic manipulations demonstrate two opposing roles of the posterior parietal cortex (PPC): generating rarity-...
