Musical Mirror Neurons Nonmusicians were trained to play a piece of music by ear on a piano keyboard, then underwent a series of fMRI scans (Lahav & others, 2007). Panel (a) shows the participants’ brain activity as they listened to the same music they had already learned to play. Even though they were not moving as they lay in the scanner, motor areas of the brain were activated (dark red). The brighter red/yellow color indicates activation in the brain’s auditory areas. Panel (b) shows participants’ brain activity while they listened to unfamiliar music utilizing the same musical notes but in a different sequence.

As you compare the scans in (a) and (b), notice the extensive activation in motor-related brain regions when the participants listened to the music that they had already learned to play, as in (a). However, these motor areas were not activated when they listened to the unfamiliar music that they had never played, as in (b).
