After earning their doctorate in neurology and becoming curious about synesthesia, Dr. Richard Cytowic and Dr. David Eagleman combined their research, thoughts, and ideas into one book; “Wednesday is Indigo Blue: Discovering the Brain of Synesthesia.” Synesthesia refers to the ability to experience different senses together. For example, you can taste words or listen to colors. Dr. Richard Cytowic, a synesthete (one who experiences synesthesia), earned a bachelor's degree in neurology from Duke. Dr. Cytowic is now a professor of neurology at George Washington University and has written numerous books, some on the topic of synesthesia. Being a synesthete, Dr. Cytowic is very effective in presenting synesthesia in this book. The other author of this book, Dr. David Eagleman, also holds a Ph.D. in neurology from Baylor College of Medicine and went on to direct the neuroscience laboratory at Baylor among many other educational and scientific pursuits. Both of these doctors are well-studied and expert in their studies of neurology and the mind. That said, they have the know-how and credentials to write this book. Synesthesia – the topic these doctors discuss – is not a well-known or well-studied topic, so these doctors are two of the few pioneers in the revival of this topic. The idea of ​​synesthesia has been around since Greek philosophers pondered the idea, but it wasn't until the 1800s that it became a specific field of scientific study. Between the 1930s and 1980s, synesthesia was pushed into the background as a new era of behaviorism became prevalent in the field of psychology. However, synesthesia made a comeback during the 1990s and has continued to become better known among the general public......middle of paper......flipped through the book I had to tell someone a few little facts that I had learned that day because it is such a fascinating topic to think about. However, I'm not saying that the whole book was just a walk in the park and a lot of fun to read, because there were points that I had to reread because I didn't quite understand what the authors were trying to say; namely because I am not an expert in the field like they are and have relatively little knowledge of psychology in general. However, the information was interestingly and creatively written and flowed very well throughout the book. As I read this book it didn't feel like a textbook on synesthesia, more like a journal with in-depth explanations. For those of you who have a nerdy side, like to learn about the mind, or maybe even experience synesthesia, I highly recommend this book..
