Product Description
For decades, scientists who heard about synesthesia hearing colors, tasting words, seeing colored pain just shrugged their shoulders or rolled their eyes. Now, as irrefutable evidence mounts that some healthy brains really do this, we are forced to ask how this squares with some cherished conceptions of neuroscience. These include binding, modularity, functionalism, blindsight, and consciousness. The good news is that when old theoretical structures fall, new light may flood in. Far from a mere curiosity, synesthesia illuminates a wide swath of mental life. In this classic text, Richard Cytowic quickly disposes of earlier criticisms that the phenomenon cannot be "real," demonstrating that it is indeed brain-based. Following a historical introduction, he lays out the phenomenology of synesthesia in detail and gives criteria for clinical diagnosis and an objective "test of genuineness." He reviews theories and experimental procedures to localize the plausible level of the neuraxis at which synesthesia operates. In a discussion of brain development and neural plasticity, he addresses the possible ubiquity of neonatal synesthesia, the construction of metaphor, and whether everyone is unconsciously synesthetic. In the closing chapters, Cytowic considers synesthetes’ personalities, the apparent frequency of the trait among artists, and the subjective and illusory nature of what we take to be objective reality, particularly in the visual realm. The second edition has been extensively revised, reflecting the recent flood of interest in synesthesia and new knowledge of human brain function and development. More than two-thirds of the material is new.

Synesthesia by SC Artist

5 Stars
May 21, 2009
In depth study of synesthesia and many examples of the experiences of synesthetes. It is a technical book aimed at psychology students/majors etc - I'm not one of those - but the vast majority of the book is nontheless comprehensible for the lay person. Make that the lay synesthete.

This book is very good reading which can reach even a a wide-scale public. The topics are interesting and convincing. The author comes over as a very communicative person. The product itself arrived within a very short period of time(within one week, shipment to Europe), surprisingly, and is well presented, good quality. In other words,good professional quality and well worth every penny.

Plenty of Depth by John Falicki (Moraga, CA United States)

I read the first edition of this book almost 20 years ago and I was blown away. Dr. Cytowic is a master of depth; I learned so much from that book that has served me well for many years. I can't wait to read this second edition. It's not just about the phenomenon of synaesthesia, it's about the brain and how it works. At bottom I would call it an outstanding text on Neurophilosophy.

A fascinating overview by Dr. Lee D. Carlson (Baltimore, Maryland USA)

Back in the sixties and seventies this reviewer used to hear various individuals describe their ability to "see" musical notes while under the influence of LSD. This claim seemed outlandish at the time, but thanks to the efforts of a few researchers, the author of this book being one of them, it is now established that there are individuals who do have this ability, along with others who experience "cross-modality" in the senses. This is now called `synesthesia' and offers enormous challenges to those who seek a neuroscientific explanation of its occurrences. For those, such as this reviewer, who are curious about synesthesia, but are not experts in neuroscience or cognitive psychology, this book offers a comprehensive but yet understandable overview. It will no doubt also satisfy the needs of students and professional researchers. Synesthesia ("joined sensation") is fascinating to contemplate, especially when reading the many anecdotal reports of people, called `synesthetes', that are included throughout the book. Some synesthetes are able to sense the color of someone's voice, while others are able to see music. The author does not want to label synesthetes as being abnormal however. Recognizing that it is rare statistically, he wants to view it as normal brain process that arises in a small number of individuals. Apparently, synesthetes are predominantly female, non-right-handed, have good memories, have in general difficulty with mathematics, but yet are highly intelligent. The author does refer to synesthetes as `cognitive fossils', which he says encapsulates best the notion that synesthesia involves the attaching of `meaning' to perceptions. It does not imply that synesthesia is "primitive" in the sense that one might be tempted to ascribe to those words. The author describes the history of research in synesthesia early on in the book. An entire chapter is devoted to the experiences as synesthetes try to describe them. One patient, designated as patient S in the book, had, amazingly, a "pentamodal" synesthesia, wherein the stimulation of one sense causes synesthesia in the remaining four. The author lists, by percentage of individuals, the different types of synesthesia, and when viewing this table, it is readily apparent that `chromesthesia', or "colored hearing" is the most prevalent type. Several questions arise when reading about the different types of synesthesia. For example, for those synesthetes who see colored shapes when listen to music, do the shapes correspond to distinct musical notes or to musical groupings of some sort? And are the shapes the same whenever the same music is listened to? The author points to the constancy of synesthesias over the lifetime of the synesthetes. In addition, their intensity and occurrence is not subject to volition. Apparently the memory of synesthetes is enhanced via the use of the parallel sense as a mnemonic device. There are therefore advantages in having some form of synesthesia. As synesthesia is an established fact it is of course natural to ask as to why it occurs and to study in detail its causes. Most of the book is devoted to these questions, both from a clinical standpoint and a neuroscientific one. As far as the region of the brain that supports synesthesia, the author argues that it is primarily in the left hemisphere and engages the temporal lobe and limbic structures. He discusses extensively the evidence for this. Readers who are not familiar with contemporary concepts in neuroscience may find the reading somewhat difficult, but the author includes some fairly detailed explanations of the anatomical features of the brain that are relevant for synesthesia. For this reviewer, the most important fact to be remembered from this discussion is that of the `module concept' of cerebral cortex architecture. A module consists of a well-defined group of approximately ten thousand cells with mutual connections that inhibit the cells of nearby modules. The modules are thus "localized" and the author believes that it is this property that explains synesthesia, rather than postulating a "cross-wiring" that occurs at the boundary between sensory entities. Central to the author's neuronal explanation of synesthesia is what he calls the `transmodal binding model', the latter in reference to the `transmodal areas'. These areas, which include the midtemporal cortex and the posterior parietal cortex, are responsible for giving meaning to words and transforming events into experiences, among other things. Clearly synesthesia is a fascinating subject, and the author is the first to admit much more research needs to be done. A perusal of the literature on neuroscience or cognitive neuroscience reveals that there is not overwhelming interest in the subject at the present time. This will no doubt change, as there is more appreciation now in scientific circles of the subjective elements of human experience, such as human consciousness. A greater understanding of the brain is needed to decide just what lies behind synesthesia as well as human consciousness. Certainly there are more surprises ahead.

Absolutely Phenominal!! by Tijs Limburg (Salt Lake City, UT)

I don't know where to begin. Cytowic is a master and genius of the world of research into synesthesia. This book contains studies and patient test results that show that synesthesia is real, and could become a breakthrough field of research and technology. I'm not even studying to be a neurologist or a medical doctor, but the factual evidences, graphs, and theories within this book captured the mind of this electrical engineering and music student. The book is absolutely thourough, as Cytowic's research must be. I especially like the quotes and stories he uses from his patients, as they attempt to explain the sensory phenomina which synesthetics see. Synesthesia, a phenominon where sound is seen with colors, taste is felt as shapes, etc. has recently been the focus of scientists alike, and has been featured in the Scientific American Magazine. The groundbreaking ideas and knowledge within this book is a must have for any intellectual, especially those with synesthesia. The technologies and discoveries that await the world of science hidden within the human mind, especially in synesthesia, are hard to fathom, but will be extremely important. That is what makes this book stand out against so many others. The ease at which Cytowic presents the data and theories is absolutely worth a five star rating. The book is absolutely worth buying, to understand the real phenomina in those around us, and within us. This book contains the roots of understanding to an infant world of research within the topic, which is bound for medical history!
