Research interests regarding the psychopharmacology of salvinorin A have been motivated by the recreational use and widespread media focus on the hallucinogenic plant, Salvia divinorum. Additionally, kappa opioid (KOP) receptor ligands may have therapeutic potential in the treatment of some...

Hypothalamic proopiomelanocortin (POMC) neurons release the endogenous opioid beta-endorphin and POMC neuron activity is inhibited by opioids, leading to the proposal that beta-endorphin acts to provide feedback inhibition. However, both intrinsic properties and synaptic inputs contribute to the regulation of...

G protein-coupled receptors (GPCRs) signal through allostery, and it is increasingly clear that chemically distinct agonists can produce different receptor-based effects. It has been proposed that agonists selectively promote receptors to recruit one cellular interacting partner over another, introducing allosteric...

Repeated intermittent administration of cocaine (20 mg kg-1, i.p.) for 3 days dramatically increased basal dopamine (DA) overflow in the nucleus accumbens (ACB) 48 h after the final daily injection. This cocaine pretreatment also produced a significant increase in stereotypy...
