About this episode

Debbii Dawson and Dr. Daw-An Wu discuss how the brain interprets reality through psychophysics.

How does the brain transform the physical world into the rich inner experience we call reality? Singer-songwriter Debbii Dawson joins Caltech neuroscientist Dr. Daw-An Wu for a conversation inspired by her songs "Where Have All the Good Men Gone" and "Chemical Attraction." Together they explore psychophysics, the science of perception, asking how illusion, consciousness, free will, love, and even spirituality emerge from the brain's interpretation of the world around us. From medullas to panpsychism, this wide-ranging discussion examines the mysterious space where objective reality becomes subjective experience.
