[单项选择]Some people have a more complicated sensory life than others. Most taste tuna only when they eat it. A few, though, taste it when they hear a particular word, such as "castanet". Others link the color red with the letter "S" or make some other inappropriate connection between stimulus and response. Such people are known as synaesthetes, and the phenomenon of synaesthesia has puzzled brain scientists since it was recognized over a century ago.

However, the development of a technique called diffusion-tensor imaging has changed that. And researchers at the University of Amsterdam have just applied it to the brains of 18 women (the sex more likely to experience synaesthesia) who have the most common form of the condition. This is called grapheme-color synaesthesia. It is a tendency to see letters and numbers in color.<
