Case pg91, fig5,6. Soma notes PHA-L injections. In all 3 cases examined, the efferent projections displayed the same basic pattern. Two bundles originate from the APc and course ipsilaterally in the descending and ascending directions, each being made of a dorsal and a ventral bunch. Terminal notes ventral bunch of the ascending bundle runs across the lateral part of the ventrobasal complex and distributes terminals into the zona incerta, especially in its pars caudalis and pars ventralis.

Case pg86, fig2. Soma notes The labelled cells were distributed essentially between two structures: the ventral lateral geniculate body and the zona incerta. Labelling particularly dense in the pars caudalis and ventralis.. Terminal notes HRP/WGA-HRP injs, In cases HP25 & HP26 the uptake area was larger and spread beyond the limits of the APc, reaching the dorsal border of the pars reticulata and the posterior thalamic nucleus. Case HP26 illustrateS the overall afferent input to the APc..
