The regionalization of [3H]dihydrotetrabenazine binding sites in the mouse brain and its relationship to the distribution of monoamines and their metabolites.
[3H]Dihydrotetrabenazine binding was measured in 8 areas of the mouse brain. In all areas, binding occurred on a homogeneous class of sites (Kd approximately equal to 2.6 nM). The density of [3H]dihydrotetrabenazine binding sites strongly varied between the different brain structures; it was compared to endogenous levels of biogenic monoamines and their metabolites: the density is independent of the nature of the monoamine and of neuronal activity, but is highly correlated to the total amount of monoamines present in each structure.
