This is a News and Views on Rouw and Scholte (2007). Increased structural connectivity in grapheme-color synesthesia. Nature Neuroscience, 10(6):792 - 797. They used diffusion tensor imaging to demonstrate increased connectivity underlies synesthetic experiences, and individual differences between synesthetes, nicely confirming a number of our predictions (see e.g., Hubbard and Ramachandran, 2005; Ramachandran and Hubbard, 2001, below).
