How does your name taste? The strange science of synaesthesia

Summary

Synaesthesia is a condition where one sense triggers another, like tasting names or seeing colors in sounds. About 2 to 4 percent of people may have it, but many do not realize their experiences are unusual. Scientists are studying how brain connections in synaesthetes work differently, possibly due to less pruning of neural links during childhood.

  • Famous synaesthetes include singer Billie Eilish and composer Franz Liszt, who saw musical notes as colors.
  • Around 2 to 4 percent of the global population experiences some form of synaesthesia.
  • Many people with synaesthesia may not know they have it because it feels normal to them.
  • Research suggests synaesthesia happens because the brain keeps more connections between senses than usual, due to less pruning of neurons in childhood.
