title: An autoradiographic study of the development of [3H]hemicholinium-3 binding sites in human and baboon basal ganglia: a marker for the sodium-dependent high affinity choline uptake system.
abstract: The developmental distribution of the sodium-dependent high affinity choline uptake (SDHACU) system has been studied in the caudate and putamen of the baboon and of the human by in vitro autoradiography with the ligand, [3H]hemicholinium-3 [( 3H]HCh3). Our results show that [3H]HCh3 binding sites in the newborn baboon and fetal human neostriatum are localized to patches, and then adopt a 'striosome-like' distribution in the juvenile baboon brain. These findings indicate a reorganization of [3H]HCh3 binding site distribution during the ontogeny of the primate neostriatum.
