You have to have a doctorates degree in neurology. M.D.
they help people who have nerve problems.
Being a neurologist wouldn't be bad because you get to help people with nerve problems.
you need endoscopic video unit for video use, ventriculostomy forceps thingy, and a neuro endo scope.
They have quite a few job responsibilities for example one of them is not mess with the wrong nerve in a persons body obviously, and another is they have to stay late hours just like a doctor, and one more is that they have to be very precise in what they do.
Basically i'm just going to wing this.
