Synesthesia is a condition in which the networks of interconnected neurons that process specific types of information for two or more senses are joined, causing cross-modal sensations.

People with synesthesia might see colors when they hear music or taste flavors when they read words.

Synesthesia may be an extreme form of cross-modal responses that most people occasionally experience, such as associating high tones with lighter colors and low tones with darker colors.

Synesthesia manifests in various forms, each offering unique sensory experiences. For example, misophonia is characterized by certain sounds eliciting intense negative emotional reactions, such as anger or fear.

Mirror-touch synesthesia involves feeling a tactile sensation when seeing someone else being touched.

Similarly, chromesthesia occurs when sounds evoke the perception of colors, creating a vivid interplay between the auditory and visual senses.

Synesthesia can enhance creativity and memory. Many individuals with synesthesia use their unique perceptions in creative fields such as art, music, and literature. However, it can also be distracting or overwhelming in everyday life.
