    Alcohol Clin Exp Res 30:791-801. 2006
    ..The current experiment investigated the predictive role of anxiety-like behaviors in ethanol self-administration and the relationship of NPY in the central nucleus of the amygdala (CeA) with anxiety and ethanol self-administration...

    Dietary Obesity Laboratory, Pennington Biomedical Research Center, 6400 Perkins Road, Baton Rouge, Louisiana 70808, USA
    Behav Brain Res 180:190-6. 2007
    ..Therefore, strain specific alterations in hypothalamic NPY may account for increased food intake in the obesity-prone rats following OBX, and suggests a potential mechanism to explain the comorbidity of obesity and depression...

    Neuropsychopharmacology 30:1589-97. 2005
    ..Rats receiving BIBP 3226 exhibited increased anxiety-related behaviors in this test. The results of these experiments provide further support for the role of amygdalar NPY in anxiety-related behaviors...
