Title: Dependence of mesolimbic dopamine transmission on delta9-tetrahydrocannabinol. Author: Tanda G, Loddo P, Di Chiara G. Journal: Eur J Pharmacol; 1999 Jul 02; 376(1-2):23-6. PubMed ID: 10440085. Abstract: Rats were administered daily for 8 days with increasing doses (2-12 mg/kg/day) of delta9-tetrahydrocannabinol (delta9-THC) and than challenged with different doses of SR141716A, an antagonist of cannabinoid receptors. SR141716A dose dependently reduced dialysate dopamine (DA) in the nucleus accumbens shell and precipitated a physical withdrawal syndrome. No such effects were obtained after administration of SR141716A to saline controls.[Abstract] [Full Text] [Related] [New Search]
