Fig. 76, Experiment IV. This figure represents a section caudal to the 

 plane of figure 75. (Compare also fig. 74.) It shows the striate cortex, marked 

 by number 17, coating the calcarine fissure {FC) and extending over the internal 

 face of the occipital lobe (upper part of the figure, corresponding with the upper 

 edge of the occipital lobe). Thus in the same section portions of the striate 

 cortex (17) alternate with those of the area parastriata {18). The boundaries 

 of the striate area (where the stria Gennari or Vicq d'Azyr, double dotted 

 intracortical stripe, ceases), are marked by an-ows. This figure demonstrates 

 the fact that the afferent visual fibers reach the striate cortex exclusively. 

 Note the manner in which visual fibers reach the upper lip of the calcarine 

 fissure and partly enter the calcar avis (latter beginning in the right lower 

 corner of the figure); the figure also demonstrates clearly the complete avoid- 

 ance by afferent visual fibers of those portions of the medullary white substance 

 which are closer to the non-striate cortex. (Compare fig. 12.)
