TABLE 5 



Nuynher of Purkinje cells per EUA in senescent cerebella. 

 Designations as in table 1 



for the insane. The uniformity of the curve is consequently 

 surprising. Much speculatidn might be based on such results 

 as these, but here it will suffice to call attention to two points: 

 first, the average loss in area 1, the head area, as compared with 

 the values from table 1, is relatively the greatest; second, in 

 areas 3 and 4, the right hemisphere suffers more than the left. 



PARESIS 



It was not originally intended to include any cases of paresis 

 in this study, but as the cerebellum of one case was prepared 

 before the cause of death was known, and as it is of interest 

 because of its similarity in cell losses to the other types of cases 

 presented, it seemed worth while to include it for purposes of 

 comparison. The results of the cell counts for this case are 

 presented in table 6. 



Here again we find the head area very low and the right 

 hemisphere much lower than the left. This was a right-handed 

 man and the cell losses have been greatest on the right side.
