Stereoelectroencephalography (SEEG) has been shown to be a valuable tool for the anatomoelectroclinical definition of the epileptogenic zone (EZ) in patients with medically refractory epilepsy considered for surgery (RES patients). In Spain, many of those patients are not offered this diagnostic procedure. ⋯ SEEG is a cost-effective technology in RES patients when compared to no SEEG intervention.

Diffusion imaging tractography caught the attention of the scientific community by describing the white matter architecture in vivo and noninvasively, but its application to small structures such as cranial nerves remains difficult. The few attempts to track cranial nerves presented highly variable acquisition and tracking settings. ⋯ This review highlights the variability in the settings used for cranial nerve tractography. It points out challenges that originate both from cranial nerve anatomy and the tractography technology, and allows a better understanding of cranial nerve tractography.

Oversight and Ethical Regulation of Conflicts of Interest in Neurosurgery in the United States.
Developmental incentives are fundamental to surgical progress, yet financial and professional incentives inherently create conflicts of interest (COI). Understanding how to manage COI held by neurosurgeons, industry, hospitals, and journal editors, without thwarting progress and innovation is critical. ⋯ Conflicts of interest are inherent to surgical innovation, and can be handled in an ethically sound manner. Neurosurgeons, device companies, hospitals, and medical journals can take steps to proactively confront bias and ensure patient autonomy and safety. These steps can preserve public trust and ultimately improve evidence-based neurosurgical practice.

Motor cortex stimulation (MCS) is routinely used for the treatment of chronic neuropathic pain but its effect on quality of life remains uncertain. ⋯ MCS improves quality of life in patients with chronic refractory neuropathic pain. Additional factors other than a simple analgesic effect may contribute to these results.
