i have decided to do neuroscience as my bachelors and some university the duration is three years should i still go ahead in order to become a neurosurgeon

Hi,

Neurosurgeons, sometimes called brain surgeons, perform surgery to repair damage to the nervous system including the brain, the spinal chord and blood vessels that feed neurological structures. Neurosurgeons diagnose problems with the help of sophisticated devices such as CT (computerized tomography), MRI (Magnetic Resonance Imaging) scans and EEGs (electroencephalograms). Becoming a neurosurgeon begins with a four-year bachelor's degree, four years of medical school, one year of internship and six to eight years of residency.

Requirements for Medical School Admission
There is no specific bachelor’s degree for neurosurgery, but a science degree that focuses on the study of the human body provides the needed credit hours. Most accredited medical schools require at least 90 undergraduate semester hours for admission. For example, Wake Forest University’s School of Medicine requires eight undergraduate semester hours (about one year) each of vertebrate zoology or general biology, general physics and general chemistry. Students are required to take eight hours of organic chemistry -- or four semester hours of organic chemistry -- and four semester hours of biochemistry. Johns Hopkins Medical School, for example, requires that applicants have a bachelor’s degree before entering medical school.

Focus on Neuroscience

A Bachelor of Arts in Neuroscience may give the prospective medical student a good background in the study of the brain and may make students more competitive for post-graduate programs in neuroscience-related fields such as medical schools. For example, the neuroscience program at Queens College of the City University of New York (CUNY) is a 55-credit hour, research-intensive program. Its neuroscience curriculum focuses heavily on psychology and physiology. The student also takes an additional 35 hours of elective courses to fulfill the 90 hours required for med school. The Society for Neuroscience lists a number of colleges that offer programs in neuroscience.

Medical School Courses
A typical medical school curriculum includes courses in anatomy and physiology, human genetics, neuroscience, hematology, obstetrics and gynecology, inpatient medicine, immunology, medical ethics, psychiatry and disease biology. Medical students wishing to specialize in neurosurgery may want to take additional graduate-level neuroscience courses.

Neurosurgical Specialty after Medical School
There are no medical school degrees specifically for neurosurgery. After the four years of medical school study required to complete a medical degree, a prospective neurosurgeon usually completes a one-year surgery internship then spends approximately six to eight years in a neurosurgery residency, training with experienced neurologists and neurosurgeons in a hospital.
