The goal of our four-week sub-internship is to provide an overview of neurological surgery for medical students planning to apply for neurosurgery residency in the next year. The sub-internship takes place on the campus of Washington University School of Medicine, and at nationally ranked Barnes-Jewish Hospital and St. Louis Children’s Hospital.

Fourth-year medical students from within Washington University and other institutions are encouraged to apply.
