    The musician Moby once said， "Music has no form whatsoever — all it is air moving just a little bit differently.It's the only art form that you can't touch." It is true that we cannot touch music，but that does not mean that music is an invisible art form.There is，in fact，a way to "see" music.
    How can we see music？Neuroscientists，people study the human brain，use MRI machines （magnetic resonance imaging machines） to look inside the brain.These tools let them see what actually happens in the brain when people are doing things.For example，the tools let them see the neurons （神經(jīng)細(xì)胞），or brain cells that are in use when people are listening to music.Computer screens linked to MRIs show neurons lighting up when they are in use.And when people listen to music，neurons light up in many parts of the brain.
    Neuroscientists have discovered that it isn't necessary to hear music for the neurons to light up.Even when you just think about a song，these neurons light up.In addition，the same neural activity in the same part of the brain happens when people experience other pleasurable activities.For example，some of the same neurons light up when we eat something delicious or hug a loved one.This is because these neurons are in the areas of the brain that reward us by making us feel good.Negative feelings such as fear or anxiety make neurons in a different area light up.However，when an anxious or frightened person listens to pleasurable music，these neurons stop lighting up.
    Now that neuroscientists can "see" the，effects of music on the brain，they want to know what the benefits of music are.It turns out there are many benefits.Neuroscientists have discovered that music can help memory and may keep our brain young.Recent studies show that an elderly musician often has a better visual memory than an elderly non-musician.For example，elderly musicians are better at memorizing a written list of words than their non-musician peers.
    Why does music have so many benefits？The answer may be because it uses so many different parts of the brain.According to neuroscientists，using many parts of the brain at one time gives your brain a good "workout." In fact，one of the best brain "works" is to read music and play a musical instrument at the same time.Reading music while playing an instrument is a challenging task.It uses more parts of the brain simultaneously than most other activities and requires excellent coordination （協(xié)調(diào)性）.It involves both physical movement and mental activity，much like playing a sport such as soccer.
    So，although Moby is completely correct that we cannot touch music，it is possible to "see" the effect of music on our brains.There is still a lot to learn about the effects of music on our brains.However，there is no doubt that scientists have shown that music is an extremely powerful art form with many positive effects.

（3）Please decide which part is false in the following statement，then underline it and explain why.
Pleasurable activities and negative feelings activate neurons in the same part of the brain，but in a different way.

Pleasurable activities and negative feelings activate neurons in the same part of the brain，but in a different way.According to the article，negative feelings make neurons in different area light up.
