case_images: Planned trajectory for the pallidothalamic tract (PTT) and ventral intermediate nucleus (Vim) in Brainlab Elements. The tip of the electrode is set to the left PTT. The bottom of the Vim is positioned 9 mm above the electrode tip.

case_images: We captured the PTT and Vim along a single trajectory by locating the entry point in the inferior parietal lobule [Figures 1 and 2].
case_images: Entry point of the electrode on the brain surface. Black arrow: Electrode (yellow) entry point on the brain surface. White arrow: Post-central sulcus. White arrowhead: Intra-parietal sulcus. The electrode entry point is at the inferior parietal lobule (IPL). M1: Primary motor cortex; S1: Primary somatosensory cortex; SPL: Superior parietal lobule.

case_images: We captured the PTT and Vim along a single trajectory by locating the entry point in the inferior parietal lobule [Figures 1 and 2].
case_images: Postoperative T1-weighted MRI at the PTT and Vim nucleus level. (a) Lesion of the left PTT located medial to the STN and anterior to the RN. (b) Lesion of the left Vim nucleus located within the Vim nucleus, as simulated by anatomical mapping of the BrainLab elements. PTT: Pallidothalamic tract, MRI: Magnetic resonance imaging, Cau: Caudate nucleus, Put: putamen, IC: Internal capsule, RN: Red nucleus, STN: Subthalamic nucleus, Vim: Ventral intermediate, VPL: Ventroposterolateral nucleus, VPM: Ventroposteromedial nucleus, ZI: Zona incerta.
