Narrator: This is Science Today. One of the largest studies to look at the correlation between music and the brains of patients with Alzheimer's disease has been conducted by neuroscientists at the University of California, San Francisco. Study leader Julene Johnson explains why they were looking at this particular group of patients.
Johnson: There seems to be something special about music and how it's represented in the brain that when somebody has Alzheimer's disease it doesn't seem to affect those parts of the brain that still preserve those musical memories.
Narrator: The researchers are using MRI imaging to better understand how different areas of the brain are responsible for different musical tasks.
Johnson: Whether you're producing music or listening to music, if you're listening for an error in music versus naming something, all of those abilities probably involve different brain networks.
Narrator: Johnson hopes this new knowledge will one day be used to design better music therapy techniques to help people with Alzheimer's and other forms of dementia. For Science Today, I'm Larissa Branin.
