The brain is generally considered the most complex part of the body. Although scientists understand its basic anatomy, much remains uncertain about how the brain impacts behavior, sensation, emotion, intelligence, and consciousness. This volume explores what is currently known about the brain's functions and how it impacts the way we understand and interact with the world around us. It also discusses some of the questions that persist about the brain and attempts to improve our understanding of the brain's activities through various scientific disciplines. Through looking at issues such as consciousness, brain injuries, and abnormal brain activity, readers will gain more insight into the complex inner workings of the brain.
