Laurel & Yanni, migraine treatment, Alzheimers & excersize, universality of music

Another multi-topic episode. We discuss the recent approval of a new treatment for migraines, then some evidence suggesting a certain kind of exercise may be therapeutic for Alzheimer's disease, and finally some work that suggests there may be universal & cross-cultural features of music. We open, however, on the debate between the Laurel & Yanni people.
