Using echo-planar magnetic resonance spectroscopic imaging procedure (EP-MRSI) to treat mental illness is a completely different approach only because of the way the magnetism is applied to the brain. The notion that the brain might respond to magnets and electricity actually goes way back. The EP-MRSI study is an example of burgeoning new research on an old idea—that the brain is an electromagnetic organ and that brain disorders might result from disarray in magnetic function. The idea has huge appeal to psychiatrists and patients alike, since for many people the side effects of psychiatric drugs are almost as difficult to manage as the disease itself. Also, 30 percent of the nearly 18.8 million Americans who suffer from depression do not respond to any of the antidepressants available now. What is it about the brain that makes it especially receptive to electromagnetic stimulation? A partial answer can be found in the neuron, the electrically and chemically excitable nerve cell that receives, processes, and transmits information in the brain. When neurons are activated by magnets or electricity, the nature of their signals changes—affecting everything from mood to cognition and memory.
【題組】Which of the following statements is true about EP-MRSI?
(A) EP-MRSI treatments have been used for mental illness for centuries.
(B) It is an advanced magnetic brain scanning technology.
(C) It is a major breakthrough in dealing with physical disorders.
(D) It has not been used on Americans who suffer from depression.
