MRIs and Synesthesia

Cognitive neuroscientists have now documented hundreds of cases of synesthesia the condition in which one sense triggers the response of a different one.

Using functional magnetic resonance imaging, behavioral neuroscientists are discovering the neurological basis of synesthesia by comparing patients’ brains with those of healthy subjects. Do you know anyone who experiences synesthesia? If you had to attribute colors to certain numbers, what would they be?
