A biologically oriented introduction to synesthesia by the leading authority on the subject.

Synesthesia comes from the Greek syn (meaning union) and aisthesis (sensation), literally interpreted as a joining of the senses. Synesthesia is an involuntary joining in which the real information from one sense is joined or accompanies a perception in another. Dr. Cytowic reports extensive research into the physical, psychological, neural, and familial background of a group of synesthets. His findings form the first complete picture of the brain mechanisms that underlie this remarkable perceptual experience. His research demonstrates that this rare condition is brain-based and perceptual and not mind-based, as is the case with memory or imagery. Synesthesia offers a unique and detailed study of a condition which has confounded scientists for more than 200 years.

How the extraordinary multisensory phenomenon of synesthesia has changed our traditional view of the brain.

An award-winning book from the author of Jeremy Fink and the Meaning of Life and The Candymakers for fans for of Wonder and Counting by Sevens Mia Winchell has synesthesia, the mingling of perceptions whereby a person can see sounds, smell colors, or taste shapes. Forced to reveal her condition, she must look to herself to develop an understanding and appreciation of her gift in this coming-of-age novel.

The uncommon sensory perceptions of synesthesia explored through accounts of synesthetes' experiences, the latest scientific research, and suggestions of synesthesia in visual art, music, and literature. What is does it mean to hear music in colors, to taste voices, to see each letter of the alphabet as a different color? These uncommon sensory experiences are examples of synesthesia, when two or more senses cooperate in perception. Once dismissed as imagination or delusion, metaphor or drug-induced hallucination, the experience of synesthesia has now been documented by scans of synesthetes' brains that show "crosstalk" between areas of the brain that do not normally communicate. In The Hidden Sense, Cretien van Campen explores synesthesia from both artistic and scientific perspectives, looking at accounts of individual experiences, examples of synesthesia in visual art, music, and literature, and recent neurological research. Van Campen reports that some studies define synesthesia as a brain impairment, a short circuit between two different areas. But synesthetes cannot imagine perceiving in any other way; many claim that synesthesia helps them in daily life. Van Campen investigates just what the function of synesthesia might be and what it might tell us about our own sensory perceptions. He examines the experiences of individual synesthetes—from Patrick, who sees music as images and finds the most beautiful ones spring from the music of Prince, to the schoolgirl Sylvia, who is surprised to learn that not everyone sees the alphabet in colors as she does. And he finds suggestions of synesthesia in the work of Scriabin, Van Gogh, Kandinsky, Nabokov, Poe, and Baudelaire. What is synesthesia? It is not, van Campen concludes, an audiovisual performance, a literary technique, an artistic trend, or a metaphor. It is, perhaps, our hidden sense—a way to think visually; a key to our own sensitivity.

Owing to its bizarre nature and its implications for understanding how brains work, synesthesia has recently received a lot of attention in the popular press and motivated a great deal of research and discussion among scientists. The questions generated by these two communities are intriguing: Does the synesthetic phenomenon require awareness and attention? How does a feature that is not present become bound to one that is? Does synesthesia develop or is it hard wired? Should it change our way of thinking about perceptual experience in general? What is its value in understanding perceptual systems as a whole?This volume brings together a distinguished group of investigators from diverse backgrounds--among them neuroscientists, novelists, and synesthetes themselves--who provide fascinating answers to these questions. Although each approaches synesthesia from a very different perspective, and each was curious about and investigated synesthesia for very different reasons, the similarities between their work cannot be ignored. The research presented in this volume demonstrates that it is no longer reasonable to ask whether or not synesthesia is real--we must now ask how we can account for it from cognitive, neurobiological, developmental, and evolutionary perspectives. This book will be important reading for any scientist interested in brain and mind, not to mention synesthetes themselves, and others who might be wondering what all the fuss is about.

Synesthesia is a fascinating phenomenon which has captured the imagination of scientists and artists alike. This title brings together a broad body of knowledge about this condition into one definitive state-of-the-art handbook.
