Map-making: Researchers at UC Berkeley used functional MRI to measure nine volunteers’ brain activity (using blood flow as a proxy) as they listened to, and then read, stories from “The Moth Radio Hour,” a storytelling podcast which airs on 500 radio stations around the world. The researchers collected volunteers’ brain activity data for reading (one word at a time, to help separate the data) and listening to recordings of the same text, then matched both sets of data against time-stamped transcriptions of the stories.
