figure 2.9 Brain imaging Researchers use brain-imaging methods to study regions of the brain that are most active during different activities. In the study whose results are shown here, pianists and nonmusicians either listened to piano music (Listening condition) or pressed keys on a piano keyboard (Playing condition). Colored areas show brain regions that were more active among pianists when listening and when playing. Images in the Combined condition show regions that were more active among pianists during both listening and playing. As you can see, although all participants performed the same musical tasks, the pianists used more “brain power” when performing them.
