This is a Dispatch on Saenz and Koch (2008). The sound of change: visually induced auditory synesthesia Current Biology, 18(15): R650-R651 in which they identified a previously unreported form of synesthesia in which visual motion elicits auditory percepts.  In this Dispatch, I discuss the implications of these findings for our understanding of the mechanisms whereby the brain integrates sight and sound more broadly.

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).
