Surgical education is moving rapidly to the use of simulation for technical training of residents and maintenance or upgrading of surgical skills in clinical practice. To optimize the learning exercise, it is essential that both visual and haptic cues are presented to best present a real-world experience. Many systems attempt to achieve this goal through a total virtual interface. ⋯ The system has provided the residents an opportunity to understand and appreciate the complex 3-dimensional anatomy of the 3 neurosurgical procedures simulated. The systems have also provided an opportunity to break procedures down into critical segments, allowing the user to concentrate on specific areas of deficiency.

Historical Article
History of the Department of Neurosurgery at Thomas Jefferson University Hospital.
The neurosurgical tradition at Jefferson Medical College began in the 19th century with Samuel Gross. In his textbook entitled A System of Surgery, Gross revealed his knowledge of the disorders of the nervous system at a time when innovations were practically inexistent. Gross' work paved the way for William Williams Keen, "America's first brain surgeon." In 1887, Keen became the first surgeon in the nation to successfully remove a primary brain tumor. ⋯ Osterholm became chairman of the Department of Neurosurgery in 1974. Since 2004, Robert Rosenwasser has served as chairman, and the Department of Neurosurgery at Jefferson has grown to include 26 faculty members. The residency has expanded to include 3 residents per academic year since 2007.

The learning and development of technical skills are paramount for neurosurgical trainees. External influences and a need for maximizing efficiency and proficiency have encouraged advancements in simulator-based learning models. ⋯ Didactic and technical quantitative scores with a simulator-based educational curriculum improved objectively measured resident performance. A minimally invasive spine simulation model and curriculum may serve a valuable function in the education of neurosurgical residents and outcomes for patients.

Carotid endarterectomy (CEA) might improve cognitive function. Fractional anisotropy (FA) values in the cerebral white matter derived from diffusion tensor magnetic resonance imaging (DTI) correlate with cognitive function in patients with various central nervous system diseases. ⋯ Postoperative increase in cerebral white matter FA on DTI is associated with cognitive improvement after uncomplicated CEA.

Virtual reality (VR) simulation-based technologies play an important role in neurosurgical resident training. The Congress of Neurological Surgeons (CNS) Simulation Committee developed a simulation-based curriculum incorporating VR simulators to train residents in the management of common neurosurgical disorders. ⋯ VR ventriculostomy placement as part of the CNS simulation trauma module complements standard training techniques for residents in the management of neurosurgical trauma. Improvement in didactic and hands-on knowledge by course participants demonstrates the usefulness of the VR simulator as a training tool.
