Lateral coordinates of nucleus ventralis intermedius target for tremor alleviation.
The lateral distance from the midline of the third ventricle to the nucleus ventralis intermedius (Vim) containing the proprioceptive neurons for arm movement, which is the site of lesion for tremor alleviation, was measured. In the brains with highly dilated third ventricle, the Vim is found displaced more laterally, at least 3 mm, than in brains with small ventricles.
