This study reports a double dissociation in the neuronal correlates of value-based decision making in monkey prefrontal cortex, with orbitofrontal cortex neurons encoding choice value relative to recent choice values, while anterior cingulate cortex neurons flexibly encode multiple decision parameters and reward prediction errors using a 'common valuation currency'.
