The nucleus accumbens (NAc) is central to heroin addiction. Activation of opiate receptors in the NAc dissociates G(i/o) into alpha and betagamma subunits. Galpha(i) inhibits cAMP production, but betagamma regulates several molecular pathways, including protein kinase A (PKA). We show in NAc/striatal neurons that opiates paradoxically activate PKA signaling(More)
