Outline of Final Research Achievements

Despite theoretical and behavioral advances of studies about salience of a cue acquired through associative learning between the cue and reward, the neural mechanisms underlying the salience remained elusive. We show that spiking activities of optogenetically-identified midbrain dopamine neurons may contribute to heighten the salience of a cue associated with uncertain reward. We also show that the orbitofrontal cortex causally contributes to reversal of stimulus-outcome associations in a context- and temporally specific manner.
