Thalamus ventralis
WebTraditionally, the ventralis intermedius nucleus of the thalamus (Vim) has been used for a target for DBS in most tremor syndromes. This clinical practice of using Vim is largely based on excellent tremor outcomes in patients with refractory ET and Parkinson disease (PD). [8] WebVerticality perception is essential for upright stance, bipedal locomotion, and spatial orientation in humans. 1-4 The estimation of verticality relative to the gravitational vector depends on otolith and semicircular canal inputs from the inner ear and is computed via an ascending neural network with the thalamus being a key hub. 5-8 Thalamic dysfunction …
