FIG. 5. A scheme of major corticosubcortical interrelations. In each figure the cerebral hemi- 

 sphere has been drawn in coronal section and the brain stem in sagittal \iew. A: .\rrangement 

 of the primary sensory pathway (dashed) and the corticospinal, corticomeduUary, corticostriatal 

 and amygdaiostriatal pathways. B: Major corticothalamic, corticorubral, corticonigral and rubro- 

 reticular connections. C: Corticopontocerebellar, cerebelloreticular, cerebellovestibular and cere- 

 bellorubrothalamic paths. D: Origin of the main subcortical motor influences descending to spinal 

 levels.
