    Abstract : Opioids such as heroin are highly addictive illicit drugs. The μ opioid receptor (MOR) plays a central role in mediating the effects of opiates and related opioid. READ MORE

  5. 18. Erasing Fear : Effect of Disrupting Fear Memory Reconsolidation on Central and Peripheral Nervous System Activity

    Keywords : Maternal deprivation; stress; mood stabilizing drugs; NPY; mood disorders; depression; anhedonia; Hinders Sensitive Line rats; Amygdala-kindling; microdialysis; RIA; histochemistry.;

    Abstract : Experiences of early adverse life events are more frequent among adult depressed patients than healthy subjects. Studies with non-human primates and rats show that maternal deprivation leads to changes in hypothalamic-pituitary adrenal (HPA)-axis activity/reactivity and increased levels of anxiety and alcohol preference.
