After earning a doctorate in neurology and becoming curious about synesthesia, Dr. Richard Cytowic and Dr. David Eagleman converged their research, thoughts, and ideas into a single book; “Wednesday is Indigo Blue: Discovering the brain of synesthesia. » Synesthesia refers to the ability to experience different senses together. For example, words can be tasted or colors can be heard. Dr. Richard Cytowic, himself a synesthete (one who suffers from synesthesia), received a doctorate in neurology from Duke. Dr. Cytowic is now a professor of neurology at George Washington University and has written several 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 earned a Ph.D. in neurology at Baylor College of Medicine and later directed Baylor's neuroscience laboratory, among many other educational and scientific activities. Both of these doctors are well researched and experienced in their studies of neurology and the mind. That being said, they have the know-how and credentials to write this book. Synesthesia – the topic addressed by these doctors – is not a well-known or well-studied topic, so these doctors are two of the few pioneers in the resurgence of this topic. The idea of ​​synesthesia has been around since Greek philosophers thought about it, but it wasn't until the 19th century that it became a specific area of ​​scientific study. Between the 1930s and 1980s, synesthesia was pushed aside as a new era of behaviorism became prevalent in the field of psychology. However, synesthesia made a comeback in the 90's and continued to become more and more well known to the general public...... middle of diary...... I read the book, I had to telling someone a little fact that I had learned that day because it's such a fascinating topic to talk about. However, I'm not saying that this whole book was just a walk in the park and a ton 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; not least because I am not an expert in the field like them and have comparatively little knowledge of psychology in general. However, the information was written in an interesting and creative way and flowed very well throughout the book. Reading this book, I didn't feel like it was a textbook on synesthesia, but rather a journal with detailed explanations. For those of you with a nerd side, who enjoy learning about the mind or perhaps even experiencing synesthesia, I highly recommend this book..
