 motor areas and are as follows: 



1. A head and eye area. 



2. A face area. 



FIG. 245. DIAGRAM OF THE MOTOR AND SENSOR AREAS ON THE MESIAL SURFACE OF 

 THE MONKEY BRAIN. (After Horsley and Schafer.) 



FIG. 246. DIAGRAM OF THE MOTOR AND SENSOR AREAS ON THE LATERAL SURFACE OF 

 THE MONKEY BRAIN. (After Horsley and Schafer.) 



3. An arm area. 



4. A trunk area. 



5. A leg area. 



The location of these areas will be apparent from an examination of Figs. 

 245 and 246.
