The definitive synesthesia book by the field’s two leading experts.

In Wednesday Is Indigo Blue, Richard Cytowic and distinguished neuroscientist David Eagleman explain the neuroscience and genetics behind synesthesia’s multisensory experiences. They show that perception is already multisensory in everybody, though for most of us its multiple dimensions are beyond the reach of consciousness. Reality, they say, is more subjective than people realize. No mere curiosity, synesthesia turns out to be a window on the mind and brain, highlighting the amazing differences in the way people see the world.

No one has done more than Richard Cytowic and David Eagleman to bring a careful neuroscientific attention to synesthesia, grounded in decades of research and reports from thousands of patients. Their work has changed the way we think of the human brain, and Wednesday Is Indigo Blue is a unique and indispensable guide for anyone interested in how we perceive the world.
