Researchers at the Laboratory of Computational Neuroscience Kyoto (Japan) have developed a technique that allows imaging of the brain to link data sleeper with certain images. This means that they can now "see" what you dream about.
A team of scientists led by Yukiyasu Kamitani conducted a study in which sleepers performed magnetic resonance imaging of the brain, identifying changes in blood flow through certain areas of the cortex. Thus, scientists determined which areas of the brain are active sleeper.
After this experiment, participants awoke and asked to tell what they have dreamed, and then they fell asleep again. By repeating this cycle every three hours, the scientists were "reports" for about 200 dreams.
In the next phase of work, researchers have collected images that were associated with the most common words in the reports, and asked participants to view these images while doing an MRI of the brain is in a state of wakefulness.
The researchers then compared the data on brain activity of sleeping and waking people who were connected with the same images.
"We have a model that allows to determine the presence or absence of a dream of a type of images — Kamitani said in an interview with Scientific American. — Analyzing data on the activity of the brain in nine seconds to wake up, we can at 75-80 per cent claim to have seen sleeping, for example, man.
At the next stage of the study, researchers will try to collect the same data concerning the so-called "REM" — when a person is dreaming more often.
"It is more difficult because in order to" catch "the test in this phase must wait at least an hour after falling asleep."
"If we learn to" read "the contents of dreams and find out how it is connected with the activity of the brain, you may be able to understand and function of the dream itself."
