Fig. 65, Experiment II. This figure represents the upper lip of the calcarine 

 fissure of figure 56 at a higher magnification (about 50 x) and turned upside 

 down, showing finer relations of the afferent visual fibers to the striate cortex. 

 Field 17 or striate area (marked by number 17) contains three intracortical 

 layers characteristic of the striate cortex, the uppermost of these correspond- 

 ing with the stria Gennari-Vicq d 'Azyr. The limit of the striate cortex at the 

 right extremity of the figure marked by an arrow. In the cortex itself many 

 degenerated afferent visual fibers do not quite correspond to the "radiated" 

 bundles, some of the first observing a more or less horizontal or oblique course 

 within the lower layers. As the afferent visual fibers reach the stripe of 

 Gennari or Vicq d'Azyr they become thinner and sparser. Note the gradual 

 decrease in thickness of the three intracortical stripes toward the boundary of 

 the striate cortex.
