Memories

Memories: Why do we remember accidents for a long time? There is hope to solve this mystery

Interesting science

Memories: He remembers more painful events that happened in the life of human beings. Our psychologists also believe that “accidents are never forgotten” is not just a proverb but a fact. But the reason for this is being researched for years. In a recent study, scientists think that now it may be known why stressful situations have such a profound effect on our memory that they are remembered for a long time. In this study, scientists have found the initial results encouraging.

Support one of the two ideologies
There are two types of ideologies in this matter. Either such memories are saved entirely differently, or they are held in the same way in the brain. This new study supports the second view. Researchers say that the formation of closely related memories under stress has a significant role in making these memories memorable.

Detailed photos of stressful experiences
Together, these memories look very different and distinct from the memories that were not created by these stressful events. Neuropsychologist Oliver Wolff of the Ruhr University Bochum (RUB), Germany, says, “Our brain usually forms detailed pictures of stressful experiences, such as taking a driving test. They last for many years. Whereas the incident of a walk in a park is quickly forgotten by the mind.

What was done in the study?
To find out why this happens, the researchers simulated a job interview with two interviewees. This is called the Trier Social Stress Test, and it is considered a reputed technique to create stress in a person. In this study, 33 participants were interviewed in a stress-producing environment, while 31 were interviewed in a friendly environment.

Study of brain response from scans
The research, published in Current Biology, took functional magnetic resonance imaging (fMRI) scans of participants and looked at the brain part associated with emotional learning. In the case of those with a stressful test, it was found that the brain has a kind of neuron-level response to the previously seen and the first sighted objects.

Emotional memory
The researchers found that the association between objects and stressful events plays a vital role in improving memory. The study suggested that the aspects related to the memory of emotional memory are more strongly associated with the brain’s emotions, that is, to the amygdala, a mechanism that controls parts of the brain related to fear, etc.

Researchers reported that experiences of objects and contexts in neutral emotional states are linked to the hippocampus (the brain part involved in learning and remembering). Still, in high emotions, the same experiences are connected to the amygdala. The results of this study, which took place in limited circumstances, inspire to make the research more comprehensive.

This study may be helpful in many types of mental disorders where memory plays a role. This may reveal more depth about the complex relationships of the brain’s memories. This research will be helpful in better understanding emotional and accidental memories.
