Recommend a book for studying the brain structure
I have a couple of reference recommendations for you, please take these with a truck load of salt as I am just an enthusiast in this field - given this, the criteria I tend to go by are - ease-to-understand and interest-factor (ie. gets me thinking) - as I do not know where you are, I am not sure of their costs for you:

Brain, Mind and the Structure of Reality (Nunez, 2010).

This book brings together neuroscience and links it to other related fields related to cognition and how we perceive the world.

Atlas of Brain Function (Orrison, 2008).

This book has a glossary as well as the details and results of imaging.

Biology of Mind (Bownds, 1999).

Even though this reference is a bit dated, it is a good starting point about brain structures and the evolution of the human brain.

Hope these are a bit helpful.
