Explain the phenomenon of 'always having human error'

British researchers have found the reason many people live in guilt, even if they are not caused by their sins.

>>>New findings about the effects of depression

According to Austrian psychiatrist and psychologist Sigmund Freud, guilt is the most common symptom of depression.

Meanwhile, British scientists believe that disruption between the two brain regions associated with guilt is the reason why people with depression live in torment because of a very small error. like: unfortunately the words.

Roland Zahn, a researcher at the University of Manchester, said: " If the information exchange activity in the brain does not work smoothly, people tend to blame themselves and cannot identify the meaning of the crime. Clear error ".

Abnormal activity in the brain makes some people live with guilt

Zahn and his colleagues focused on the subclinical cortical cortex and the septum area close to this brain region - the area deep within the brain involved in guilt.

Previous studies have shown that abnormal activity in the brain region, also known as SCSR, usually occurs in people with depression.

SCSR is responsible for exchanging information with the anterior temporal lobe area located on one side of the skull. The front temporal lobe is activated during the process of thinking about moral issues including sin and indignation.

Therefore, the researchers suspected that channels of communication between SCSR and the front temporal lobe made people feel guilty instead of being innocent.

Scientists have conducted research on 25 volunteers. They had a history of depression but had completely escaped the disease for at least a year before participating in the study.

All 25 volunteers received magnetic resonance imaging (fMRI) - a brain scan image that shows the blood flow pumped up over active areas in the brain. During fMRI shooting, each patient read pre-written sentences that imply guilt or indignation. These sayings all have the name of the volunteer and the name of their best friend.

Next, the researchers compared the brain activity of the volunteers with 22 healthy people. These people are divided into pairs of the same age, education level and gender for comparison.

The results showed that in the brains of healthy people, the SCSR region and the temporal lobe work together when they read statements that cause sin and indignation.

In contrast, for those who have suffered from depression, these two areas operate differently. Accordingly, during the period of indignation, the SCSR region and the temporal lobe of those with depression experienced working together but entered a sense of guilt, these two areas could not synchronize activities.

In addition, for those who always tend to receive errors about themselves, the distance between SCSR and the front temporal lobe is greatest. Especially with volunteers who have been depressed, they cannot distinguish different feelings while reading sinful and indignant statements.

Currently, the researchers have not been able to conclude exactly whether abnormal brain activity or depression is the cause of disruption of the link in the pre-temporal SCSR and temporal lobes.

Fortunately, according to Mr. Zahn, the ability to link SCSR and the front temporal lobe can be completely improved through training. That means that patients with depression can learn to overcome feelings of guilt.

This is the motivation for Mr. Zahn to cooperate with scientist Jorge Moll of D'Or Research and Education Institute in Rio de Janeiro (Brazil) to build a training program for human brain activity. In it, patients will observe their own real-time brain images to learn how to change emotions.
