The decarboxylation of DOPA in the parkinsonian brain: in vivo studies on an animal model.


The site of decarboxylation of exogenously administered L-DOPA was studied in corpora striata of rats with near-total unilateral nigrostriatal lesions. After DOPA administration, the absolute increases in dopamine (DA) levels were lower in lesioned than in unlesioned striata, suggesting that, in the intact striatum, a major part of exogenous DOPA is… (More)
