"MRI scans performed during REM sleep revealed that brain activity fell in the amygdala—the emotion-processing part of the brain—possibly allowing the more rational prefrontal cortex to soften the images' impact. (See an interactive brain map.) In addition, recordings of the subjects' electrical brain activity during sleep made with electroencephalograms showed a decrease in the levels of brain chemicals linked to stress. When people experience an emotional event, stress chemicals are released to flag and prioritize that event, essentially reminding the brain to work through it during sleep, according to Walker, whose study appeared November 23 in the journal Current Biology. "Somewhere between the initial event and the later point of recollecting, the brain has performed an elegant trick of divorcing emotions from memory, so it's no longer itself emotional," Walker said."
