Dreams help us to overcome the painful memories
Research indicates that the dream may help people cope with pain because of the difficult memories.
U.S. researchers found that chemicals in the brain associated with stress drop during the dreaming stage of sleep - sleep REM - and that the brain processes responsible for emotional experiences.
Researchers at the University of California, Berk reduced chemicals in the brain helps to reduce the pain associated with difficult memories, and as a kind of "cure overnight."
Provided evidence for why we dream, say researchers in this study may help to explain some of the symptoms of post traumatic stress disorder (PTSD), such as recurrent nightmares. And said to the people who suffer from PTSD, this treatment may not be overnight and does not work as effectively as it should.
They divided 35 volunteers into two groups. Both groups showed 150 images designed to provoke an emotional response, while the MRI measures brain activity.
Look at the pictures of the first group in the morning and evening, while the second group viewed their pictures in the evening and the next morning after sleeping the whole night.
Observed in the images of the group that slept a full night that the emotional reactions decreased, compared with the group that did not sleep.
Magnetic resonance images showed the group, which had not slept little activity in the amygdala, a part of the brain that processes emotions, and also more activity in the prefrontal cortex, the part of the brain associated with rational thinking.
The researchers also used electroencephalograms)) EEG to record brain electrical activity of the volunteers as they slept. Found that during sleep, REM, dropped some of the patterns of electrical activity, which indicated low levels of chemicals in the brain responsible for stress.
Dr. Matthew Walker, who led the study: "We know that during REM sleep and a sharp decline in the secretion levels Alnurabenevran (norepinephrine), a chemical in the brain associated with stress.
"It is through past experiences and we found that the decrease in the secretion of the chemical norepinephrine during sleep, REM, you'll wake up the next day, and we feel that the emotional experiences decreased sense of it, and we can deal with it."
