  A New Scietist urlLink link because, well, its just plain weird in my book. Oh, and so you had something a little more fresh to look at;) "New research has revealed a molecular basis for the “Mozart effect” – the observation that a brief stint of Mozart, but not other music, may improve learning and memory.
One theory on the Mozart effect is that the particular rhythmic qualities of Mozart’s music mimic some rhythmic cycles occurring in human brains. According to new research, rats that heard a Mozart sonata expressed higher levels of several genes involved in stimulating and changing the connections between brain cells. The results of this research will help in the development of music therapy treatments for people suffering from neurodegenerative disesases such as Alzheimer’s. "
