Magnetic resonance-guided focused ultrasound is a powerful new technology that is enabling development of noninvasive applications for complex brain disorders. This is currently revolutionizing the treatment of tremor disorders, and a variety of experimental applications are under active investigation. To fully realize the potential of this disruptive technology, many challenges have been identified, some of which have been addressed and others remain to be solved. ⋯ While lesioning is the primary approved application of magnetic resonance-guided focused ultrasound at present, the ability to transient and precisely open the blood-brain barrier has the potential to clear brain pathologies and deliver restorative therapies, but this more experimental method presents unique difficulties to overcome. Finally, regulatory and reimbursement hurdles currently remain complex and continue to limit widespread application of even approved, effective applications. Here we review many of these challenges, discuss several solutions that have already been developed, and propose potential options for addressing some of these complexities in the future.

Lenticulostriate artery aneurysms (LSAs) are rare vascular aberrations. Despite the potentially catastrophic sequelae of aneurysmal rupture, the optimal management strategy for LSA aneurysms has not been determined. The aim of the present review is to provide an overview of the clinical presentation and treatment strategies for LSA aneurysms. ⋯ We have summarized the reported cases of LSA aneurysms, with their clinical presentation, management, and outcomes, for physicians who may be confronted with this diagnosis. Future studies that use available classification systems and include as much detail as possible should be encouraged to fully elucidate the optimal management strategy for these patients.

Extended length of stay (LOS) after surgery is costly to the health care system and can be distressing to the patient and family. Previous studies have shown conflicting data on factors associated with increased LOS and are limited by using multiple different surgeries. Our study seeks to analyze factors that are associated with extended LOS. ⋯ Nurick gait, operative time, and history of weak narcotic use are associated with extended hospital stay. These data may be useful in preoperatively counseling patients, developing quality metrics for hospitals, and helping create financial models for cost/diagnosis-related group reimbursement for single-level anterior cervical surgery.

The coronavirus disease 2019 pandemic poses major risks to health care workers in neurocritical care. Recommendations are in place to limit medical personnel attending to the neurosurgical patient as a protective measure and to conserve personal protective equipment. However, the complexity of the neurosurgical patient proves to be a challenge and an opportunity for innovation. The goal of our study was to determine if telemedicine delivered through smart glasses was feasible and effective in an alternative method of conducting ward round on neurocritical care patients during the pandemic. ⋯ Virtual ward rounds using telemedicine via smart glasses on neurosurgical patients in critical care were feasible, effective, and widely accepted as an alternative to physical ward rounds during the coronavirus disease 2019 pandemic.

Single neuron or unit recording enables researchers to measure the electrophysiologic responses of single neurons using a microelectrode system. This approach is widely used in cognitive science and has become more widespread in humans with the use of hybrid (micro-within-macrowire) depth electrodes that enable the implantation of microwires into the brain parenchyma. ⋯ The addition of hybrid depth electrodes for the purpose of in vivo single neuron recording in robot-enhanced stereoencephalography procedures is safe and does not impact the accuracy of targeting or patient safety.
