Synaesthesia

July 28th, 2009

From the Ancient Greek σύν (syn), “together,” and αἴσθησις (aisthēsis), synaesthesia is a neurologically based phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway.  People who experience this fusion of sense are known as synesthetes.
