Abstract

Mesolimbic dopamine (DA) was measured by ventral striatum (including nucleus accumbens) microdialysis in freely moving streptozotocin (STZ)-diabetic male rats. DA and dihydroxyphenylacetic acid (DOPAC) basal levels and amphetamine-induced DA increase were lower in diabetic than in normal rats. These results are discussed in terms of decreased DA neuron activity and DA receptor hypersensitivity in the mesolimbic system of STZ-diabetic rats.
