Imagine being able to hear or taste colors or see music swirling before your eyes. No, this isn’t some groovy flashback to the psychedelic '60s. It’s actually a neurological condition called synesthesia, which activates more than one sense simultaneously. According to some estimates as many as 1 in 200 people — mainly women — have it. The most common type involves perceiving numbers, letters or words in color (e.g., the letter A might always appear pea green). However, other synesthetes, for example, may hear “The Star-Spangled Banner” whenever they taste chocolate or smell lavender when someone touches their hand. The multi-sensual combinations are practically endless.
