People can learn to forget bad memories

According to an American study published in Science magazine, our brains have the ability to deliberately erase bad memories from memory.

Neuroscience researcher Brendan Depue of the University of Colorado, one of the co-authors of the study, hopes this finding will help find new therapies for treating emotional disorders like fear, obsession. and stress state due to a traumatic experience.

The researchers invited participants to memorize 40 pairs of images, including an expressionless, " lifeless " face with a horrifying image like a wounded soldier, a chair. electricity for criminal execution or a street accident.

Volunteers then had to go through an exercise to determine when they saw a "lifeless" face, they could recall or deliberately forget about the same horrifying image.

Through brain MRI, the researchers found that the two frontal cortical areas of the frontal cortex acted in succession to disable the activity of other special areas in the brain such as the visual cortex , the hippocampus. and amenorrhea play a role in visual and emotional memories.

According to the researchers, the anterior frontal cortex of the frontal cortex plays a major role in intentionally deleting the memory. This is a relatively new characteristic in the evolution of the human brain.

If the Stone Age hunters had escaped the lion's claws while hunting for antelope and did not forget these fears, they would stop hunting and starved to death.

However, researchers have not determined how many training sessions need to be performed, a soldier injured by the war or a person who has experienced a serious accident can learn to forget painful experiences. this.
