Music has a huge impact on activity in the brain. You can physically/visually see the growth and changes that happen inside it. Until recently, scientists did not know how music affected the brain. The advancement in technology allows scientists to actually “see” brain activity via PET scans and MRI imaging. Our brains are “wired” with neural pathways. Most activities only cause a portion of the brain to “light up” with activity. But there are actually four parts to the brain and music makes ALL of the areas “light up” and create new neural pathways which remain intact and can be used for other things.
