A team of Japanese researchers has developed a device capable of recording and interpreting dreams, combining neuroscience and Artificial Intelligence (AI).

According to a publication in the Brazilian newspaper "Mail"This is a technology based on functional magnetic resonance imaging (fMRI), which monitors brain activity during sleep and promises that people can immerse themselves in their dreams and reproduce them digitally.

The tests involved participants who, upon entering the rapid eye movement (REM) phase, were woken up to describe their dreams. "The recorded neural activity patterns allowed the algorithm to predict, with 70% accuracy, the reported content," explain the researchers.

According to the same publication, the technology focuses on REM sleep, a phase in which the brain reaches high levels of activity, creating the scenarios characteristic of dreams. fMRI was used to map this task in detail, making the discovery possible.

The scientists stressed that the development involved years of study into the different stages of human sleep, especially NREM stages 1, 2, 3 and REM sleep. "It is in the REM phase that the brain builds dreams, and our research has focused on understanding these processes," the team concluded.
