Passage 2

It began as just another research project, in this case to examine the effects of various drugs on patients with a severe mood disorder. Using an advanced brain scanning technology—the clumsily named echo-planar magnetic resonance spectroscopic imaging (磁共振光谱成像)procedure，or EP-MRSI—researchers at Boston’s McLean Hospital scanned the medicated and unmedicated brains of 30 people with bipolar disorder in order to detect possible new treatments for the more than 2 million American adults who suffer from the disease.

But something unexpected happened.A patient who had been so depressed and could barely speak becameebullientafter the 45-minute brain scan. Then a second patient, who seemed incapable of even a smile, emerged actually telling jokes. Then another and another. Was this some coincidence? Aimee Parow, the technician who made these observations ( she is now a medical student in New York) didn51 think so. She mentioned the patients’striking mood shifts to her boss, and together they completely refocused the study：to see if the electromagnetic fields might actually have a positive effect on depressive mood.

As it turns out, they did.As reported last month in the American Journal of Psychiatry, 23 of the 30 people who were part of the study reported feeling significantly less depressed after the scan. The most dramatic improvements were among those who were t
It’s a completely different approach because of the way the magnetism is applied to the brain. But it’s an example of new research on an old idea that the brain is an electromagnetic organ and that brain disorders might result from disarray in magnetic fu
