As you can already see, there are at least two approaches to neurosurgery: people who love neuroscience and want to work directly with the brain, spinal cord (and yes) peripheral nerves, and people who love surgery and want to surgerize the brain and cord, but would be just as happy working in other surgical fields.
While this may be a gross oversimplification, i think it holds true in more than a few cases. Personally, i have no interest in general surgery--i dont relish asking patients about the moment to moment aspects of their bowel movements, i dont really find the biliary tree particularly interesting, and am not excited by whipples or multi-visceral transplants. ENT isnt my thing either-seems like almost brain surgery, but not quite to me. Ortho is kinda cool, but my arms arent twice the size of my thighs, so im out. I like neurology, but the endless rounding with no real solutions is too much for my attention deficoid nature.
I want to work with and treat disorders of the nervous system. I guess my ideal field would be one which focused on the nervous system as a whole, and which encorporates all the tools available, be they medical or surgical (artificial distinctions in my opinion) in the treatment of the nervous system. Reality doesnt work that way unfortunately, and I decided Id rather work on the surgical side of neuroscience than the medical...truth be told however, Id rather be a neurologist and work with the nervous system, than a general surgeon and work with poop and pus.
