TED-Ed: What color is Tuesday? Exploring synesthesia - Richard E. Cytowic

The video explores synesthesia, a neurological phenomenon where senses are intertwined, affecting 4% of the population. It describes various types, such as colored hearing and synesthetic tastes, and explains how synesthesia is a trait rather than a disorder. The video discusses genetic and cultural influences, the role of synesthesia in enhancing memory, and its connection to metaphor creation. It concludes by explaining how non-synesthetes perceive metaphors due to inherent sensory mappings.
