听力原文如下：

M: What I really want from you guys is that you learn how music can affect our feelings, really grasping the essence of music.Actually, you already knew music has an influence on human's feeling in many ways before ever coming to this class. However, I'd like focus on "how to do this" today.Actually, it's the thing about humans. Music is universal form and has been so in every human civilization since the beginning of time.It's like we're hard-wired to appreciate music.

Okay, when we hear music, it stimulates some areas of our brain.In addition to this, when we hear a low frequency sound transforming to a high frequency sound, it actually makes our brain react in a certain way.So, this is what I want to talk to you about today, a research done on the relationship between music and the brain. This research involved Positron Emission Tomography, or PET scan. This is a kind of scan that can project three dimensional images of the internal organs, and can even detect and display the areas in the brain that are being stimulated.

Here's one experiment. Researchers asked subjects to listen to music, and they used the PET scan to detect what areas in the brain were being stimulated. Well. so what did they find out? One region is very obvious, the area of the brain devoted to audio stimulation. I mean, it's music, right? But, the thing that was really amazing was that another area of the brain lit up.

It's the part that handles visual information. This was definitely something that the researchers had not anticipated. Now,if you think about it, it's really amazing that the visual area lit up because of audio stimulation.

Specifically,the areas that lit up are called Brodmann areas 18 and 19, known as the mind's eye. There is a visual cortex in each hemisphere of the brain. The left hemisphere visual cortex receives signals from the right visual field and vice versa. These areas like a mental canvas. So, when you listen to music, your mind tries to symbolize an image to go well with that sound. These two areas are in the outer layers of the cerebral cortex.
