Since 2002, some fMRI investigations of grapheme-color synesthesia—the most widely studied kind—have shown that graphemes stimulate the V4 region of the brain.
This is consistent with a model where the regions of the brain that analyze graphemes and that deal with color are somehow hyper-connected to create a synesthetic event.
