Michio Kaku has a great book called the 'The Future of the Mind'. Not exactly the most reputable since he's a theoretical physicist and not a neuroscientist.

His writing though, is very easy to read. He gives a great overview of how humanity has thought about the brain throughout history, important scientific discoveries, and where neuroscience is at now. The rest of the book is his speculation about where he thinks we will go in the future with neuroscience.
