open_questions › What resolves this contention: Whether ventral striatum is a 'pure' model-free RPE locus (Glascher 2010) or a mixed MB+MF prediction-error structure (Daw 2011). / State prediction errors (model-based) and reward prediction errors (model-free) are encoded in anatomically distinct regions: SPE in IPS/lateral PFC, RPE in ventral striatum. / Ventral striatal prediction-error signal contains both model-free AND model-based components in proportion to behavioral arbitration, contradicting strict anatomical segregation. › diff
