I hear movements: why motor brain regions are active when we listen to musical rhythms

Sounds and movements are intimately linked. Who has not experienced the urge to tap to the beat of a marching band, or sway their hips to a samba tune? Even babies spontaneously move their bodies with music before they can crawl or walk, and a cockatoo named Snowball can tap his feet in time with a popular tune. Music has also been harnessed to help people with brain injury move again. Currently, however, there is no explanation for why listening to music compels us to move. To gain insight into this mystery, my research will discover how the brain links sounds and movements.
