Synaesthesia and DNA

Did you know that synaesthesia appears to have roots in DNA? Synaesthesia is a fascinating phenomenon whereby, in some individuals, cross-wiring occurs between the senses. It can take many forms and seems to run in families, although it also appears to be affected by environmental factors. Studies of this phenomenon at the University of Oxford in England have uncovered regions of human DNA that wires some people to “see" sounds or “hear” colors in ways that do not occur in the brains of non-synaesthetes.
