The film has become a reality! Scientists have developed a method to erase bad memories.

The film titled "Eternal Sunshine of the Spotless Mind," which tells the story of a man who erases the memories of his ex-girlfriend, has become a reality. An international research team conducted an experiment aimed at erasing bad memories. Participants were asked to associate random words with negative images, and then the goal was to reprogram half of these associations. The research results showed that the recall of negative memories was weakened and the involuntary recollection of positive memories was increased. According to the information reported by Science Alert in the Proceedings of the National Academy of Sciences (PNAS), the researchers stated, "We found that this procedure weakened the recall of negative memories and increased the involuntary recollection of positive memories."

RECODING WITH POSITIVE IMAGES

In the study, well-known databases containing negative images, such as human injuries or dangerous animals, and positive images, such as serene landscapes or smiling children, were used. On the first evening, participants received memory training to associate negative images with meaningless words created for the research. The next day, after these memories were reinforced by sleep, half of the words were attempted to be recoded by associating them with positive images.

INTERVENTION DURING SLEEP

On the second night, during the non-rapid eye movement (NREM) sleep phase, which is known to be important for memory storage, audio recordings of the meaningless words were played. During this process, brain activities were monitored using electroencephalography (EEG). It was observed that theta wave activity, associated with emotional memory processing in the brain, increased in response to auditory memory cues and was significantly higher for positive cues.

POSITIVE MEMORIES BEGAN TO COME TO MIND MORE FREQUENTLY

In surveys conducted the next day and a few days later, it was found that participants were less successful in recalling bad memories mixed with positive memories. Positive memories associated with these words began to come to mind more frequently than negative ones and were evaluated with a more positive emotional perspective.

THE METHOD HOLDS PROMISE

The researchers stated, "Non-invasive sleep intervention can change negative recollections and emotional responses. Our findings may offer new perspectives on the treatment of trauma or pathological memories." Although the research is still in its early stages, this method is said to hold promise. Studies are ongoing on how more complex memories can be organized under real-world conditions and how long these effects can last.
