CNN新闻节选：

Music is language of the brain stimulates feelings, thinking processes, the motor system, 

we have substantial hard science evidence how music can help the brain.

Some of the areas that musical memories are located and actually not attacked by Alzheimer's disease.

老师： that musical memories are located 这一部分没看懂， 这里that是副词=where吗？are located 后面为什么没有介词例如 in 呢？

麻烦老师详细分析that和located.

另外，我在词典上看到一个例句：These popular apartments are centrally located. （这些抢手的住宅都位于中心地带） 

这里的located是直接用作形容词，后面不需要介词in了吗？
