Chart 3 Showing the relative vascularity of the five cortical areas studied 

 and of the five laminae in each. Based on table 24. 



/, lamina zonalis 

 ///, lamina pyramidalis 

 IV, lamina granularis interna 

 V, lamina ganglionaris 

 VI, lamina multiformis 



I, insular area 

 O, occipital area 

 P, parietal area 

 Pr, praecentral area 

 T, temporal area 



From these data it appears that on the average the vascular 

 supply to the cortex is about 5.08 times that to the white mat- 

 ter in the ventral funiculus of the cord, and about 1.12 times 

 that to the gray matter in the ventral horn.
