Hippocampal seizures and striatal regulation: a possible functional pathway.

abstract：:The effect of dopamine on the 3',5'-cyclic adenosine monophosphate (cAMP) generating system of membrane particles of rat prostate gland was studied. Dopamine increased the concentration of cAMP in a dose-dependent manner. The selective D1 receptor inhibitor SCH 23390 caused a decrease in dopamine-elicited cAMP levels....
