    Eur J Neurosci 24:2643-53. 2006
    ..These results provide direct neurophysiological evidence that exposure to cocaine can cause behaviorally relevant changes in the processing of associative information in a circuit that includes the orbitofrontal cortex...

    Thomas A Stalnaker
    Department of Anatomy and Neurobiology, University of Maryland School of Medicine, Baltimore, MD 21201, USA
    Neuron 54:51-8. 2007
    ..These results are consistent with the hypothesis that OFC facilitates cognitive flexibility by promoting updating of associative encoding in downstream brain areas...

    Thomas A Stalnaker
    Department of Anatomy and Neurobiology, University of Maryland School of Medicine, Baltimore, MD 21201, USA
    Ann N Y Acad Sci 1121:598-609. 2007
    ..A similar mechanism of drug-induced orbitofrontal-amygdalar dysfunction may cause inflexible behavior when animals and addicts are exposed to drug-associated cues and contexts...
