Abstract

Repeated administration of high doses of methamphetamine produced long-term decreases in dopamine (DA) levels and in the number of DA uptake sites in the rat striatum. These two effects were dose-related and did not appear to be due to the continued presence of drug in striatal tissue. Long-lasting depletions induced by methamphetamine were selective for striatal DA neurons since norepinephrine (NE) levels in all of the rat brain regions examined were not changed on a long-term basis by methamphetamine treatments. Supersensitivity of DA receptors did not accompany the loss of striatal DA and its uptake sites.
