TABLE 8 
Giving for each litter group in this study the average brain weight, the corrected areas 
of the cortex in the sagittal and frontal sections, and the area of the entire frontal 
section, respectively, compared with the corresponding standard values for the 
same brain weight. The standard values are all entered according to my previous 
presentation (Sugita, ’18b). This table was condensed from an original complete 
table 8a for each individual. The averages for the test and control groups are given 
at the end of the table.
