Regions proposed to be cross-activated in grapheme-color synesthesia (from Ramachandran & Hubbard 2001).. Since regions involved in the identification of letters and numbers lie adjacent to a region involved in color-processing (V4), the additional experience of seeing colors when looking at graphemes might be due to "cross-activation" of V4 (Ramachandran & Hubbard 2001).
