Why, where and how do top-down and bottom-up signals interact in the primate brain?

2025-06-12

Abstract excerpt

<p>Here we propose a roadmap for addressing hierarchical predictive coding theory (hPC) in the primate brain, theorizing that perception arises from the integration of top-down (TD) pathways carrying priors and predictions with bottom-up (BU) pathways carrying sensory evidence in the form of precision weighted prediction errors. However, given the conceptual importance of hPC for higher cognitive function in human...
