Music Mapped in Brain
Why do humans enjoy music so much? We may be one step closer to finding out. Researchers at the Massachusetts Institute of Technology analyzed fMRI images and determined that a certain set of neural pathways located within the auditory cortex activates exclusively to the sound of music. Other noises, such as a dog barking or a door slamming, leave these circuits silent. According to the authors, this is one of the first studies establishing that speech and music circuits are in different parts of the auditory cortex (and that each circuit is largely deaf to the other’s sound cues).
