Striatal symptoms

Classical striatal symptoms were interpreted through identification of the underlying projection system, by physiological analysis of neuronal activity of each subnucleus in the base of the thalamus during stereotactic procedures for various involuntary movements. Rigidity, levodopa-induced dyskinesia, idiopathic dyskinesia, symptomatic athetoid movement and symptomatic choreic movement, as well as that in Huntington's disease, belong to the category of striatal symptoms. These symptoms may be alleviated by surgery on the pallido-Vo-complex projection, which is the main output affected by disorders due to striatal dysfunction.
