Updating dopamine reward signals

Highlights ► Dopamine prediction errors are influenced by model-based information. ► Dopamine neurons show limited activations to punishers when proper controls are made. ► Dopamine neurons do not code salience to a substantial extent. ► Intact dopamine mechanisms are required for learning and posys...

Zusammenfassung:	Highlights ► Dopamine prediction errors are influenced by model-based information. ► Dopamine neurons show limited activations to punishers when proper controls are made. ► Dopamine neurons do not code salience to a substantial extent. ► Intact dopamine mechanisms are required for learning and posysynaptic plasticity.
