Branching Pattern and Geometrical Properties of Dendritic and Axonal Arborizations in the Striato-Pallido-Thalamic System in Macaques
Recently, different organizational levels of the striatopallidal and pallidothalamic projections have been studied through various experimental approaches. This has brought to light important characteristics of this major part of the basal ganglia system. For example it has been shown that the medial pallidum receives a specific and significant input from the lateral pallidum (Smith et al., 1994b), that a single medial pallidal neuron receives both striatal and subthalamic afferences (Bevan et al., 1994) or both subthalamic and lateral pallidal afferences (Smith et al., 1994a; Smith et al., 1994b), that striatopallidal and subthalamopallidal axons end in the form of longitudinal bands in both the lateral and medial pallidal nuclei (Hazrati and Parent, 1992).
