In a study published in the Journal of Neuroscience, researchers from the Gallant Lab at UC Berkeley scanned the brains of nine participants while they read and listened to a series of tales from "The Moth Radio Hour." After analyzing how each word was processed in the the brain's cortex, they created maps of the participants' brains, noting the different areas helped interpret the meaning of each word.
Looking at the brain scans and data analysis, the researchers saw that the stories stimulated the same cognitive and emotional areas, regardless of their medium. It's adding to our understanding of how our brains give semantic meaning to the squiggly letters and bursts of sound that make up our communication.
