Deep brain stimulation of the ventral intermediate nucleus of the thalamus (VIM-DBS) is an established treatment for medically refractory essential tremor. However, the effect of VIM-DBS on vocal tremor remains poorly understood, with results varying by method of vocal tremor assessment and stimulation laterality. This single-center study measures the effect of bilateral VIM-DBS on essential vocal tremor using blinded objective acoustic voice analysis. ⋯ Objective acoustic voice analyses suggest that bilateral VIM-DBS effectively reduces vocal tremor rate and improves voicing. Further studies using objective acoustic analyses and laryngeal imaging may help refine surgical and stimulation techniques and evaluate the effect of laterality on vocal tremor.

Treatment-resistant depression is a leading cause of disability. Our center's trial for neurosurgical intervention for treatment-resistant depression involves a staged workup for implantation of a personalized, closed-loop neuromodulation device for refractory depression. The first stage ("stage 1") of workup involves implantation of 10 stereoelectroencephalography (SEEG) electrodes bilaterally into 5 anatomically defined brain regions and involves a specialized preoperative imaging and planning workup and a frame-based operating protocol. ⋯ Our protocol outlined for SEEG electrode implantation incorporates tractography and frame-based stereotaxy.

Despite the globalization of health information, collaborations between high-income countries (HICs) and low/middle-income countries (LMICs), while present, could still increase. This study builds on previous research highlighting LMIC underrepresentation in neurosurgery literature. We conducted a comprehensive bibliometric analysis using the Scopus database to investigate collaborative neurosurgical research between HIC institutions and those in low-income country (LIC)/LMICs. ⋯ Global guidelines and consensus papers can enhance patient care, but LMICs' involvement remains limited. Further attention to training and collaboration initiatives is needed. This study emphasizes the importance of promoting collaboration and training between countries with varying resources to advance neurosurgical care globally.

Financial conflicts of interest between editorial board members and industry could lead to biases and impartial editorial decisions. We aimed to evaluate the frequency, amount, and characteristics of payments to editorial board members of neurosurgery journals over a 6-year period. ⋯ Around 54% of editorial board members of neurosurgical journals received industry payments between 2017 and 2022. We identified journal-specific trends in industry payments and highlighted the importance of transparency and disclosure of financial conflicts of interests for neurosurgery journals.
