Stereoencephalotomy and control of skeletal muscle tone.
Stereotactic interventions at the thalamic or subtalamic level for treatment of pathological hyperkinesias provide a good model for investigation of the systems controlling tonic innervation in the alert subject. It is suggested that the poststereotactic muscular hypotonia observed contralaterally to the lesion is due to changes in the tonic innervation pattern caused by interruption of a proprioceptive feedback loop.
