The effects of brain stimulation on memory formation in humans have shown conflicting results in previous studies. We hypothesized that direct cortical stimulation using an implanted responsive neurostimulation (RNS) system will improve memory. ⋯ Verbal memory improves by direct cortical stimulation during a list-learning task. The RNS system can be effectively used in memory research using direct cortical stimulation. This study has implications in the development of neurostimulation devices for cognitive enhancement in conditions such as epilepsy, dementia, and traumatic brain injury.

Tumors that arise in and around the skull base comprise a wide range of common and rare entities. Recent studies have advanced our understanding of their pathogenesis, which in some cases, have significantly influenced clinical practice. The genotype of meningiomas is strongly associated with their phenotype, including histologic subtype and tumor location, and clinical outcome. ⋯ The identification of nonoverlapping genetic drivers of adamantinomatous craniopharyngiomas and papillary craniopharyngiomas indicates that these are distinct tumor entities and has led to successful targeted treatment of papillary craniopharyngiomas using BRAF and/or mitogen-activated protein kinase inhibitors. Similarly, dramatic therapeutic responses have been achieved in patients with Langerhans cell histiocytosis, both with BRAF -mutant and BRAF -wildtype tumors. Familiarity with the pathology of skull base tumors, their natural history, and molecular features is essential for optimizing patient care.

The Safety and Effectiveness of the Contour Neurovascular System (Contour) for the Treatment of Bifurcation Aneurysms: The CERUS Study.
The Contour is a novel intra-aneurysmal flow disrupting device to treat intracranial aneurysms. ⋯ The Contour seems to be both safe and effective in the treatment of intracranial bifurcation aneurysms.

Observational Study
Understanding the Natural History of Postoperative Pain and Patient-Reported Opioid Consumption After Elective Spine and Nerve Surgeries With an Automated Text Messaging System.
There is a gap in understanding how to ensure opioid stewardship while managing postoperative neurosurgical pain. ⋯ Using real-time, patient-centered pain assessment and opioid consumption data will allow for the development of evidence-based opioid prescribing guidelines after spinal and nerve surgery.
