    ..Drug. Alcohol Depend. 78, 83-90). Since outcome uncertainty is a critical element of risk, we investigated whether such individuals have different neural responses to uncertainty than their stimulant-naive peers...

    Department of Psychiatry, University of California, San Diego, USA
    Biol Psychiatry 63:184-90. 2008
    ..The need to inhibit behavior is often forewarned by cues that do not call for immediate inhibition. We sought to determine whether such cues would engage the ACC and improve inhibition in MD individuals...

    ..Here, the hypothesis is examined that stimulant-using subjects adjust their decision making less as a function of errors as evidenced by attenuated behavioral and neural substrate activation patterns...
