1932] Poliak: Afferent Fiber Systems, Primate Cerelral Cortex 241 



Fig. 36, Experiment I. A figure showing the section where the instrument 

 reached the pulvinar from the internal capsule (L = lesions). All fiber bundles in 

 the ventral portion of the pulvinar were interrupted and degenerated towards the 

 superior colliculus of the midbrain (Colsup). They form the brachium of the 

 colliculus and enter mainly the superficial medullary layer of the colliculus. 

 (Compare with fig. 96.) The pulvinar is completely separated from the hemi- 

 sphere. Superior parietal gj'rus (PS), inferior parietal gyiois (PI).
