Abstract: | ![]() δ9-Tetrahydrocannabinol (10 mg/kg) increased homobanillic acid in rat prefrontal cortex and olfactory tubercle. This dose did not affect homobanillic acid in the caudate. Higher doses increased homobanillic acid in all 3 regions. Cocaine (20, 30, or 50 mg/kg) did not affect homobanillic acid in any of these brain regions. |
