Richard E. Cytowic MD will join us for a 'Please Explain' on synesthesia. One in twenty-three people carry the genes for the synesthesia. This neurological trait vividly creates cross-sensory couplings. A synesthete might hear a voice and at the same time see it as a color or shape, taste its distinctive flavor, or feel it as a physical touch. Cytowic will tell stories from his book,  Synesthesia, and answer all your questions. This segment is guest hosted by Nancy Giles.
