I am not a neurosurgeon (neurologist rather), but neuroanatomy is a particular hobby of mine.
The advice you have already received is very sound.
Atlases? There are many sources to choose from.
My personal favorite is by Duane E. Haines, PhD. It's Neuroanatomy: An Atlas of Structures, Sections, and Systems. The sixth edition is the most current.
Another favorite is by Albert Rhoton, MD. It's essentially a hardback compendium titled Cranial Anatomy and Surgical Approaches that was originally presented in two supplementary issues of Neurosurgery in September of 2000, and October of 2002.
You might also like Atlas of the Human Skull, by H. Wayne Sampson, John L. Montgomery, and Gary L. Henryson.
All make for excellent reading (if you happen to like this flavor of topic).
