Synesthesia

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

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.

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.

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.

Revealing the neuroscience and genetics behind synesthesia—and how this multi-sensory phenomenon changed our view of the brain. A person with synesthesia might feel the flavor of food on her fingertips, sense the letter “J” as shimmering magenta or the number “5” as emerald green, hear and taste her husband’s voice as buttery golden brown. Synesthetes rarely talk about their peculiar sensory gift—believing either that everyone else senses the world exactly as they do, or that no one else does. Yet synesthesia occurs in 1 in 20 people, and is even more common among artists. One famous synesthete was novelist Vladimir Nabokov, who insisted as a toddler that the colors on his wooden alphabet blocks were “all wrong.” His mother understood exactly what he meant because she, too, had synesthesia. Nabokov's son Dmitri, who recounts this tale in the afterword to this book, is also a synesthete—further illustrating how synesthesia runs in families. Wednesday Is Indigo Blue reveals how the extraordinary multisensory phenomenon of synesthesia has changed our traditional view of the brain. Because synesthesia contradicted existing theory, researcher Richard Cytowic spent 20 years persuading colleagues that it was a real—and important—brain phenomenon rather than a mere curiosity. Today, scientists in 15 countries are exploring synesthesia and how it is changing the traditional view of how the brain works. Cytowic and neuroscientist David Eagleman argue that perception is already multisensory, though for most of us its multiple dimensions exist beyond the reach of consciousness. Reality, they point out, is more subjective than most people realize. No mere curiosity, synesthesia is a window on the mind and brain, highlighting the amazing differences in the way people see the world.

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.

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.
