Cover of the October issue of Neurosurgical Focus: Video. Patient spirals before (red) and after (green) magnetic resonance–guided focused ultrasound (MRgFUS) ablation targeted at the dentatorubrothalamic tract show significant improvement in hand tremor. The postoperative lesion can be seen in the left thalamus, as well as the remnant of the patient’s first MRgFUS lesion, from 9 months prior, in the right thalamus. See the article by Seas et al. (V2).
