Synesthesia

By Renée Grinnell

Neurologically based misperception or “cross-wiring” of sensory modalities. Individuals with synesthesia might perceive letters or numbers as possessing inherent colors, or they might associate colors with certain musical tones.

Example: A patient reports that environmental sounds cause his skin to tingle, and that being touched causes him to see fireworks.
