Neural Circuit Evidence for Hierarchical Processing of Prediction Errors: Distinct Cerebello–Frontal Connectivity for Phonological and Semantic Errors
Predictive coding theories posit that the brain processes prediction errors (PEs) across multiple levels, yet explicit neural circuit evidence for these mechanisms remains elusive. This study investigated effective connectivity within the right cerebellum (RC)–left inferior frontal gyrus (LIFG)–left middle frontal gy...
