What training do Neurosurgeons have?

Neurosurgery is one of the longest training periods of all the medical specialties because of the extreme complexity of the nervous system and the advanced technique used in this specialty. Following college, training includes four years of medical school, a one-year internship, and a five- to seven-year neurosurgical residency. Upon completion of the residency and two years in practice, the surgeon is eligible to take the American Board of Neurological Surgery examination.
