Music can cause your brain to grow
Italian neuroscientists have reported that bombarding mice with easy listening music increases levels of brain-derived neurotropic factor (Wikipedia), in their hypothalmus specifically. However, levels of another neurotropic factor, NGF (nerve growth factor), declined. The findings suggest, according to the authors, that physiological effects of music, such as lowered blood pressure and heart rate or mood improvements, “might in part be mediated by modulation of neurotrophins.”
