1932] Poliak: Afferent Fiher Systems, Primate Cerebral Cortex 277 



Fig. 72, Experiment III. The upper lip of the calcarine fissure of figure 71 

 under higher magnification. It shows the upper horizontal branch of the visual 

 radiation degenerated and already descended into the upper lip. (Compare 

 with fig. 57.) The visual fibers supply exclusively the striate area niarkcd with 

 number 17, which contains a double dotted intracortical stripe, its boundary 

 marked by an arrow. Since in this experiment the "boundary bundle" of the 

 visual radiation was interrupted, the limit of the supplied cortical segment and 

 of the striate cortex coincides exactly. None of the afferent visual fibers enters 

 the non-striate cortex (marked with 18) or even approaches it.
