The operation procedure was as per previous report [6 ]. All cases underwent pre-operative MR-imaging on a 3.0 T scanner using a T1 image, T2-weighted image and fused with pre-operative CT with fame. Leksell G head frame and Surgiplan system (Elekta AB, Stockholm, Sweden) were adopted. Pre and Post-operative high-resolution CT images were acquired in all the cases. CT examination was repeated within 6 days post-operatively to exclude intracranial hemorrhage, pneumocephalus and to confirm the position of electrodes and contacts.
Surgiplan system

As previously reported [6 ], pre-operative MRI and post-operative CT input Lead-DBS software (https://www.lead-dbs.org/ ) were used [8 (link)]. Post-operative images were linearly co-registered to pre-operative images using the Statistical Parametrical Mapping software version 12 [SPM12] [9 ] and BRAINSFit software [10 ]. The three-dimensional images of the electrode and the nucleus were saved in the database after comparison with Surgiplan system (Elekta AB, Stockholm, Sweden) so that the stimulation parameters could be adjusted quickly according to the reconstruction results during remote programming [11 (link)].

Leksell G head frame and Surgiplan system (Elekta AB, Stockholm, Sweden) were adopted. After implanting electrodes under local anesthesia, a bone hole was sealed with biomedical fibrin glue. Then, an external neurostimulator was connected to carry out intraoperative macrostimulation tests and record the threshold value of efficacy and adverse reactions of electrical stimulation. The test cathode contact was the most inferior contact, and the anode contact was the superior contact. The electrodes are 3389 (Medtronic, Villalba, USA) or L301 (PINS, Beijing, China). Stimulation parameters were as follows: pulse width: 60 μs; frequency: 130 Hz; with the voltage increasing from 1.5 V to 5.0 V gradually. Side effects were observed and recorded. After fixing the electrode with Stimloc (Medtronic, Villalba, USA) or Leadloc (PINS, Beijing, China), the scalp was sutured. If the position of the electrode was satisfactory after confirmed by a 1.5 T MRI (Siemens MAGNETOM Avanto, Germany) scanning with frame, an extension lead and implantable pulse generator were implanted under general anesthesia.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
