A prosthesis that can communicate with and be controlled by your brain. A microchip placed in the eye of a person previously blind that allows the patient to see again. A machine that can tell us what a person is thinking about. Drugs tailor made for a specific person to help them deal with emotional issues. The stuff of science fiction? No. It is reality. The human brain is not only our most complex organ, but also the most complex entity known to mankind. We are in an age of fantastic and prolific neurological research with advances occurring faster than in any other scientific field. This research promises to help us with our mental health, social adjustment, satisfaction with life, our ability to learn, and our ability to remember, (and forget). The brain contains approximately 90 billion neurons. We are beginning to understand their functions more and more each day. This three-pound organ the shape of a cauliflower has fascinated man for centuries. The study of the brain is now less philosophical and more scientific. As neurological research becomes more and more enlightening and practical, a general understanding of the brain and the major issues of neurological science become more important. It is not rocket science or brain surgery (pun intended) to have a basic understanding of the state of our knowledge of the brain today. This book will acquaint the reader with thirty of the most important and interesting topics in the study of the brain. The author will assume that the reader has limited knowledge of the brain and it's functions, and will present information in every day language with very limited use of scientific jargon. The brain is responsible for how we perceive our world and how we behave in it. Let us begin our journey of understanding it.
