• Dopamine discharge encodes changes in expected free energy under posterior vs. prior policy beliefs, representing precision updates.claim0.811
  Links dopamine to precision modulation; reward prediction error reflects expected free energy changes.
• Midbrain dopamine neurons fire above baseline for rewards better than predicted, at baseline for matching predictions, and below baseline for worse-than-predicted rewards, matching the temporal difference errorfinding0.767
  The foundational finding linking dopaminergic activity to formal RL prediction error
• Dopamineconcept0.756
  Neurotransmitter reinterpreted not merely as reward signal but as encoding conditional certainty/precision of predictions; modulates top-down and bottom-up balance.
• These dynamics are consistent with predictive processing since active inference prescribes dynamics that minimise prediction error.concept0.751
  Connection between active inference neuronal dynamics and predictive processing theory.
• Modern machines, including quantum computers and machine learning systems, achieve reliable function through uncertain events, making unpredictability a feature rather than a defect.claim0.744
  Argument that predictability is no longer an essential property distinguishing machines from life
• The temperature parameter regulating precision of policy selection has a clear biological interpretation in terms of confidence encoded in dopaminergic firing.claim0.744
  Links precision to dopamine, Section 6.3.
• Dopaminergic Reward Prediction Errorconcept0.735
  Midbrain dopamine neurons encoding TD error; the most extensively studied evaluative system
• What are the neuronal mechanisms by which prior beliefs from one agent's model are received and properly implemented by a naive agent (neuronal hermeneutics)?question0.734
  Open question about inter-agent communication beyond model-space assumption
