Importance of the Cerebellar Hemisphere in Production of Tremulous Movement or Choreo-Dystonic Movement in Monkeys
Experience of the use of stereotaxic surgery in Parkinsonism and for different kinds of tremulous movements, and analysis of the results have led to the conclusion that the surgical target for tremor and that for rigidity is slightly different in respect of localization within the thalamus. Tremor is located posteriorly in the Ventralis Intermedius Nucleus (Vim) and rigidity is anteriorly in the Ventralis Lateralis Nucleus (VL). In our several previous reports, differentiation of these two subnuclei was discussed in detail.
