HEMIPLEGIA. 105 



of the corpus striatum of the opposite side, we find 

 the following phenomena : 



Complete Hemiplegia from Lesion of the Eight 

 Corpus Striatum.* 



1. The head turns to the right. 



2. Both eyes turn to the right, and frequently 

 both upper eyelids are fallen. 



3. The muscles of the belly and chest are weak- 

 ened on the left. 



4. The muscles passing from the trunk to the 

 left limbs are paralyzed. 



5. The face is paralyzed on the left side. 



6. The tongue on protrusion turns to the left. 



7. The left leg is paralyzed. 



8. The left arm is paralyzed. 



Such is the combination of movements, and the 

 compound posture, resulting from a destructive 

 lesion of the right corpus striatum. 



Now, to consider a few of the special movements 

 in more detail. Lateral deviation of the eyes and 

 head both eyes turn to the right as a result of 

 destruction of the right corpus striatum, and the 

 head turns in the same direction. This is an in- 

 teresting phenomenon for comparison with modes 

 of expression by head rotation (see p. 185). 



In the case of a right-sided brain lesion, the head 

 rotates to the right on account of the weakened 

 condition of the left muscles, so that those on the 

 right side pull it over to .the non-paralyzed side.
