Designations of areas in figure 2. 



Fig. 2. Lateral and dorsal views of the left half of the brain to show the 

 regions in which the measurements of vascularity were made. The exact loca- 

 tion and relations of each of the areas represented is based on a comparison of 

 figures by Fortuyn and Sugita, the names being applied in accordance with 

 Sugita's correlation of Brodmann's terminology with these figures. Comparison 

 with Brodmann's own figures and description seems to indicate that the anterior 

 portion of area B is equivalent to the regio postcentralis. A, regio praecentralis; 

 B, regio parietalis; C, regio temporalis; D, regio occipitalis; E, regio insularis. 



TABLE 24 



Average vascularity of the five areas of the cerebral cortex in the unit volume 



For each area the datum is the average of the five laminae. The ratio of the vas- 

 cularity in each area of the cortex to that of the ventral white matter and the ventral 

 gray matter of the spinal cord, respectively, is also entered. Based on table 3,
