Lonely people have a unique brain signature, perhaps due to so much imagined social contact
Researchers at McGill University in Canada used information from UK Biobank , an open database in the United Kingdom, to study brain scans of 38,701 people. The breakdown of the subjects is that 47.5% are male, 52.5% are female, and the age is 40 to 69 years. Subjects answered a questionnaire about whether they were lonely, and 13% of the respondents said they felt lonely. Of these, 39% were men and 61% were women.
When the research team analyzed the relationship between the survey results and brain scan images, those who answered that they were lonely compared to those who answered that some of the brain areas called ' default mode networks ' were not lonely. Turned out to be big. The default mode network is said to be a part related to self-awareness and memory, and is said to be activated when a person introspects or imagines something.

Previous studies have shown that those who feel lonely are more likely to concentrate by thinking in their heads to make up for their lack of social experience. These people's thinking patterns include above-average 'recollections' and 'imaginary social interactions,' which could have affected the realm of default mode networks by increasing their thinking about themselves.
