The limbic system, which is involved in processing emotions and controlling memory, “lights” up when our ears perceive music. The chills you feel when you hear a particularly moving piece of music may be the result of dopamine, a neurotransmitter that triggers sensations of pleasure and well-being. It provides a total brain workout. Research has shown that listening to music can reduce anxiety, blood pressure, and pain as well as improve sleep quality, mood, mental alertness, and memory.
