Neural correlates of reward prediction errors (RPEs) have been found in dorsal striatum. Such signals may be important for updating associative action representations within striatum. In order that the appropriate representations can be updated, it might be important for the RPE signal to be specific for the action that led to that error. However, RPEs signaled by midbrain dopamine neurons, which project heavily to striatum, are not action-specific. Here we tested whether RPE-like activity in… CONTINUE READING
