Episode notes
Synesthesia as Sensory Experience
- Synesthesia is a genuine sensory experience, not merely metaphorical or made up.
- Individuals with synesthesia perceive it consistently and strongly, as evidenced by cases like the twins arguing over the color of Tuesday.
Neural Basis of Synesthesia
- Synesthesia likely arises from a failure to prune neural connections during development.
- These unpruned connections link seemingly unrelated sensory areas, leading to cross-sensory experiences.
Acquired Synesthesia
- Synesthesia typically originates early in life, often before individuals can remember not having it.
- However, acquired synesthesia can occur in adulthood due to sensory loss or drug use.
