‘Inception’ device to decode dreams
Scientists in Japan said Friday they had found a way to “read” people’s dreams, using MRI scanners to unlock some of the secrets of the unconscious mind.
Researchers have managed what they said was “the world’s first decoding” of night-time visions, the subject of centuries of speculation that have captivated humanity since ancient times.
In the study, published in the journal Science, researchers at the ATR Computational Neur-oscience Laboratories, in Kyoto, western Japan, used magnetic resonance imaging (MRI) scans to locate exactly which part of the brain was active during the first moments of sleep.
The scientists then woke up the dreamers and asked them what images they had seen, a process that was repeated 200 times.
These answers were compared with the brain maps that had been produced by the MRI scanner, the researchers said, adding that they later built a database, based on the results.
On subsequent attempts they were able to predict what images the volunteers had seen with a 60 percent accuracy rate, rising to more than 70 percent with around 15 specific items including men, words and books, they said.
“We have concluded that we successfully decoded some kinds of dreams with a distinctively high success rate,” said Yukiyasu Kamitani, a senior researcher at the laboratories and head of the study team. “Dreams have fascinated people since ancient times, but their function and meaning has remained closed,” Kamitani told AFP
