Comparison of Dopamine Uptake in the Basolateral Amygdaloid Nucleus, Caudate‐Putamen, and Nucleus Accumbens of the Rat
Abstract: Regional differences in the kinetics and pharmacological inhibition of dopamine uptake were investigated with fast‐scan cyclic voltammetry in both the intact rat brain and a brain sliceExpand
