Likewise in disease of the optic thalami, the symptoms of hemichorea, of athetosis, 

 and of unilateral tremor were observed not very infrequently. These have also been 

 observed following lesions of other parts of the brain, yet were commonly concerned

The same difficulty presents itself when an attempt is made to determine the 

 symptoms of disease of the corpus striatum. What was for a, long time described 

 as such (hemiplegia, for example) may arise just as well through the involvement 

 of the neighboring capsula interna. A case is known of the destruction of both 

 putamina which terminated without a, symptom referable thereto.
