Richard Cytowic's dinner host apologized, andquot;There aren't enough points on the chicken!andquot; He felt flavor also as a physical shape in his hands, and the chicken had come out andquot;too round.andquot; This offbeat comment in 1980 launched Cytowic's exploration into the oddity called synesthesia. He is one of the few world authorities on the subject.

Sharing a root with anesthesia (andquot;no sensationandquot;), synesthesia means andquot;joined sensation,andquot; whereby a voice, for example, is not only heard but also seen, felt, or tasted. The trait is involuntary, hereditary, and fairly common. It stayed a scientific mystery for two centuries until Cytowic's original experiments led to a neurological explanationandmdash;and to a new concept of brain organization that accentuates emotion over reason.

That chicken dinner two decades ago led Cytowic to explore a deeper reality that, he argues, exists in everyone but is often just below the surface of awareness (which is why finding meaning in our lives can be elusive). In this medical detective adventure, Cytowic shows how synesthesia, far from being a mere curiosity, illuminates a wide swath of mental life and leads to a new view of what is means to be humanandmdash;a view that turns upside down conventional ideas about reason, emotional knowledge, and self-understanding.

andquot;Phenomena that are robust and repeatable but don't fit the 'big picture' of accepted Science are often regarded as anomalies and unfairly ignored by the establishment. Synesthesiaandmdash;the mingling of sensesandmdash;is one such topic. In this reprint of his classic work, Dr. Cytowic has once again revived interest in this fascinating topic.andquot;
