Randomized Controlled Trial Comparative Study
Neuronavigated vs. conventional repetitive transcranial magnetic stimulation method for virtual lesioning on the Broca's area.
This study was undertaken to test the hypothesis that repetitive transcranial magnetic stimulation (rTMS) using a neuronavigational TMS system (nTMS) to the Broca's area would elicit greater virtual aphasia than rTMS using the conventional TMS method (cTMS). ⋯ nTMS leads to more robust neuromodulation of Broca's area, resulting in delayed verbal reaction time as well as more accurate targeting of the intended stimulation location, demonstrating superiority of nTMS over cTMS for therapeutic use of rTMS in neurorehabilitation.

Guided (VENTRI-GUIDE) versus freehand ventriculostomy: study protocol for a randomized controlled trial.
Despite the widespread use of external ventricular drainage, revision rates, and associated complications are reported between 10 and 40%. Current available image-guided techniques using stereotaxy, endoscopy, or ultrasound for catheter placements remain time-consuming techniques. Recently, a smartphone-assisted guide with high precision has been described. The development of an easy-to-use, portable, image-guided system could reduce the need for multiple passes and improve the rate of accurate catheter placement. This study aims to prospectively compare in a randomized controlled manner the accuracy of the freehand pass technique versus an easy-to-use, portable, adjustable guiding device for ventriculostomy catheter placement. ⋯ This is the study design of a single center, prospective, randomized controlled trial to investigate whether guided ventriculostomy is superior to the standard freehand technique. One strength of this study is the prospective, randomized, interventional type of study testing a new easy-to-handle guided versus freehand ventricular catheter placement. A second strength of this study is that the power calculation is based on catheter accuracy using an available grading system for catheter tip location, and is calculated with the use of recent study results of our own population, supported by data from prominent studies.

Case Reports Randomized Controlled Trial
Clinical evaluation and follow-up outcome of presurgical plan by Dextroscope: a prospective controlled study in patients with skull base tumors.
Patient-specific approach design, comprehensive evaluation on perioperative data, and follow-up of postoperative life quality (KPS) were carried out to evaluate the application of VR technology of Dextroscope in procedures of patients with skull base tumors. ⋯ The preoperative plans with VR technology in patients with skull base tumor or CSF leakage operations can help certain the diagnosis, individually locate the position of skull base lesions, and design patient-specific approach, which also facilitate to shorten operation duration and the postoperative LOS, reduce total blood loss and injury of vessels in operation, and improve the postoperative KPS.

Implantation of a responsive neurostimulator device in patients with refractory epilepsy.
The authors summarize one center's experience with a novel device, the Responsive Neurostimulation (RNS) system, which is used to treat seizures, and they provide technical details regarding the implantation procedure. ⋯ The results obtained in this small preliminary series demonstrate a safe implantation method for the responsive neurostimulation device.
