for her term project, a girl in my physio class chose to explore the topic of listening to music and its relation to the brain. it was a very interesting idea, as so many of us listen to music, and we were given more insight into the activity of the brain during a period of hearing music. this article provides a similar slice of info and I just thought it was cool.
