Seeing sound, tasting color | David Eagleman

Imagine Thursday. Does Thursday have a color? What about the sound of rain - does that sound taste like chocolate? Or does the sound of a saxophone feel triangular to you?
For about 3% of the population, the sharp lines between our senses blend together. Textures may have tastes, sounds, shapes, numbers may have colors. This sensory crosstalk is called synesthesia, and it's not a disorder, just a different way of experiencing the world.
To learn about the neuroscience behind this fascinating phenomenon and what it tells us about how our brains perceive the world, we were fortunate enough to speak with David Eagleman, a neuroscientist, author, and entrepreneur here at Stanford. Eagleman has long been fascinated by synesthesia and what it means about how our perceptions shape our reality.
We also discuss Eagleman's work with Neosensory, a company that develops technology to help individuals with hearing loss by translating sound into vibrations on the skin. The episode highlights the adaptability and plasticity of the brain, offering a deeper understanding of how our perceptions shape our reality.
In addition to his research, Eagleman is a prolific communicator of science - the author of several books including Livewired and Incognito and host of the PBS series "The Brain with David Eagleman" and the new podcast series "Inner Cosmos".
Enjoy!
