Time and decision making: differential contribution of the posterior insular cortex and the striatum during a delay discounting taskMarc Wittmann
Department of Psychiatry, University of California San Diego, 9500 Gilman Drive, La Jolla, CA 92093 9116A, USA
Exp Brain Res 179:643-53. 2007....
Young adult stimulant users' increased striatal activation during uncertainty is related to impulsivityDavid S Leland
Laboratory of Biological Dynamics and Theoretical Medicine, Department of Psychiatry, University of California, San Diego, USA
Neuroimage 33:725-31. 2006..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...- Anterior cingulate cortex and benefit of predictive cueing on response inhibition in stimulant dependent individualsDavid S Leland
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... - Reduced behavioral and neural activation in stimulant users to different error rates during decision makingMartin P Paulus
Laboratory of Biological Dynamics and Theoretical Medicine, Department of Psychiatry, University of California, San Diego, California, USA
Biol Psychiatry 63:1054-60. 2008..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... - Impaired time perception and motor timing in stimulant-dependent subjectsMarc Wittmann
Department of Psychiatry, University of California San Diego, 9500 Gilman Drive, La Jolla, CA 92093 9116A, USA
Drug Alcohol Depend 90:183-92. 2007..Altered time processing in SDI could explain why SDI have difficulty delaying gratification... - Individuals with schizophrenia present hypo- and hyperactivation during implicit cueing in an inhibitory taskEstibaliz Arce
Laboratory of Biological Dynamics and Theoretical Medicine, University of California San Diego, CA 92093 0985, USA
Neuroimage 32:704-13. 2006..The primary purpose of this investigation was to assess the neural correlates of implicit cueing during an inhibitory task in schizophrenia when performance accuracy was matched with healthy comparison subjects... - Increased risk-taking decision-making but not altered response to punishment in stimulant-using young adultsDavid S Leland
Laboratory of Biological Dynamics and Theoretical Medicine, Department of Psychiatry, University of California, San Diego, CA 92093-9116, USA
