    University of California Los Angeles, Department of Psychology, Los Angeles, CA 90095, USA
    Biol Psychiatry 71:846-54. 2012
    ..Fast dopamine signaling is hypothesized to mediate this form of learning by reporting errors in reward prediction. However, such a role for dopamine release in voluntarily initiated action sequences remains to be demonstrated...

    Neuroscience 163:770-80. 2009
    ..These data suggest that an intact endogenous opioid system is necessary for normal goal-directed learning and more importantly, reveal that a compromised endogenous opioid system during learning enhances the habitual control of actions...
