Synaesthesia

Synaesthesia is a neurological phenomenon where the stimulation of one sense involuntarily triggers experiences in another sense. For example, a person might see colors when hearing music or associate specific tastes with words. This occurs because the brain's sensory areas are interconnected differently, causing cross-activation. Synaesthesia is not a disorder but a genuine variation in perception that varies among individuals. It can enhance creativity and perception, and typically remains stable over time. While rare, it provides a unique insight into how our brains process sensory information.
