Histological findings after injections of high-concentration (800 mm) MnCl2 in OFC of monkey P. A, Thionin staining revealed two areas of complete cell loss in OFC areas corresponding to injection locations. cgs, Cingulate sulcus; los, lateral orbital sulcus; mos, medial orbital sulcus; ps, principal sulcus. B, Higher-power view of the more medial lesion shown in A. This lesion falls within the injection site shown in Figure 2A. The needle track itself is also visible. C, Immunocytochemistry revealed no differences in tyrosine hydroxylase levels in ipsilateral (ipsi) striatal targets of manganese transport versus the corresponding contralateral (contra) areas. Cd, Caudate; Pu, putamen; VS, ventral striatum; cc, corpus callosum; ic, internal capsule.
