IN previous studies in the monkey, it was observed that there is a direct relationship betwen interruption of ascending nervous fibers at level ventromedial area upper brain stem, retrograde cellular degeneration ipsilateral substantia nigra,<sup>1</sup>and depletion dopamine both parts homolateral striatum.<sup>2-4</sup>Similarly, serotonin striatum attributed to most dorsomedial cerebral peduncle on corresponding side.<sup>5,6</sup>These neuroanatomical and neurochemical changes are...
Abstract A morphological study of the red nucleus and its efferent nervous pathways based on retrograde cellular degeneration (cell loss) degenerated fibers impregnated with osmic acid gave folowing results. Interruption rubro‐tegmentospinal tract was associated a complete disappearance cells in contralateral magnocellular some cell loss adjoining tegmental gray. central bundle results parvicellular part ipsilateral nucleus. Such lesion is rubro‐olivary that terminate along dorsal lamella...
Lesions were placed in the left ventromedial tegmental area of brains nine monkeys (Macaca mulatto). After 1–4 months, removed, and striatum was dissected prepared for chemical analysis. In seven animals which lesion strictly unilateral, striatal dopamine very much reduced below level found on intact side brain. two impinged right brain, concentration both sides. Homovanillic acid 3,4-dihydroxyphenylacetic acid, metabolic derivatives dopamine, measured striata four five respectively. Both...
The spontaneous activily of the putamen and related structures was studied on both sides brain in cats with chronic unilateral lesions interrupting corresponding nigrostriatal pathway at level upper midbrain or area medial forebrain bundle. frequency activity recorded these animals after high cervical cord transection greater deprived its incoming fibers than intact side normal cat. Under such conditions l-dopa increased lesion but not side. These results suggest that absence endings...
