    Psychopharmacology (Berl) 211:175-85. 2010
    ..Little is known about mechanisms underlying female rodent aggression during the late postpartum period with no pups present. Studies of aggression, dominance, and oxytocin (OT) response in cocaine-treated females are sparse...

    Department of Psychiatry, The University of North Carolina at Chapel Hill, Chapel Hill, North Carolina 27599, USA
    Pharmacol Biochem Behav 81:769-85. 2005

    Josephine M Johns
    Department of Psychiatry, The University of North Carolina at Chapel Hill, 424 Taylor Hall, CB 7096, Chapel Hill, NC 27599 7096, USA
    Int J Dev Neurosci 22:321-8. 2004
    ..Results of the present study support previous data indicating that alterations in oxytocinergic and perhaps serotonergic system dynamics in the amygdala may play a role in cocaine-induced postpartum aggression...

    Josephine M Johns

    Dev Neurosci 24:522-30. 2002
    ..This study also demonstrates gender-specific development of serotonin (5-HT(1A)) receptors across postnatal ages, demonstrating a fundamentally different pattern of development of 5-HT(1A) receptors between males and females...
  7. ncbi An oxytocin antagonist infused into the central nucleus of the amygdala increases maternal aggressive behavior
    Deborah A Lubin
    Department of Psychology, University of North Carolina at Chapel Hill, 27599, USA
    Behav Neurosci 117:195-201. 2003
    ..OTA did not affect other behaviors, suggesting that disruption of oxytocin activity in the CNA may be sufficient to selectively alter maternal aggressive behavior...

    Kathleen C Light
    Department of Psychiatry, School of Medicine, University of North Carolina, CB 7175 Medical Building A, Chapel Hill 27599 7175, USA
    Addict Behav 29:1541-64. 2004
    ..Although they tended to hold their babies less often at home, baby holding in the laboratory led to decreased BP in cocaine mothers who then did not differ from no-drug mothers in BP or observed affect...

    Neurotoxicol Teratol 31:291-302. 2009
    ..Prenatal exposure to these drugs sex-specifically decreased ethanol preference behavior in offspring unlike reports for either drug separately. The possible role of oxytocin in reduction of ethanol consumption behavior is highlighted...

    Paul E M Phillips

    Brain Res 961:63-72. 2003
    ..We conclude, therefore, that behavioral changes that have previously been observed in rats that were prenatally exposed to cocaine are not mediated through alteration of presynaptic dopaminergic mechanisms in these brain regions...
