Subpopulations of mesencephalic dopamine containing neurons possess different electrophysiological, pharmacological, biochemical, and anatomical properties. In order to determine whether such differences are related to the regulation of tyrosine hydroxylase, the rate limiting enzyme in the synthesis of catecholamines, the regional distribution of tyrosine(More)
Cytochrome oxidase (COase) activity, an endogenous marker of neuronal activity, was examined in the substantia nigra of the adult rat at the light-microscopic level. In addition, the pattern of histochemical staining observed for COase activity was correlated with immunohistochemistry for tyrosine hydroxylase (a marker of dopaminergic neurons) and for(More)
Changes in striatal dopamine turnover and levels of tyrosine hydroxylase messenger RNA were examined in mice injected with D2 selective doses of fluphenazine-N-mustard, an irreversible blocker of dopaminergic receptors. The animals were killed at different times after acute and repeated injections of the drug and dopamine turnover was assessed by measuring(More)
