Summary: With host Angela Eaton Can you taste music? Do your numbers appear as colors? Do your senses blend? Synaesthesia (US spelling synesthesia) is an inherited condition which causes unusual perceptions or associations, triggered by everyday activities like reading, speaking, or eating. For example, synaesthetes might perceive colours when listening to music, or tastes in the mouth when reading words. Synaesthesia has been linked to differences in white/grey matter structure, and can involve direct sensory crossing (e.g., sound to vision), or can be mediated by higher level functions such as language.
