It turned out that the characteristics of the brain are different between the morning type person and the night type person in the first place.

There are morning type people who are good at early rising and night type people who like late-night activities. It is thought that genes are related to morning type/night type, and personality is also affected. Is believed to be. There are differences in various aspects of life, morning type/night type, but it is clear from the brain scan of more than 3,700 people that there are differences in the brain in the first place.

Diurnal Preference and Gray Matter Volume in a Large Population of Older Adults: Data from the UK Biobank

Night owls have more gray matter in their brains than early birds

The brain is divided into three tissue types: gray matter , white matter, and cerebrospinal fluid . Generally, the gray matter processes information, while the white matter is a “road” for sharing information in different parts of the brain. It is believed to play a role.

Previous studies have shown that brain gray matter density and mass differ between people with high and low empathy. In a new study, Dr. Ray Norbury, a senior psychology lecturer at Brunel University in the United Kingdom, compares brain scans from 3730 people from the UK Biobank. A sample of 3730 people was clearly determined to be morning/night type by a questionnaire survey, and Dr. Norbury investigated whether there was a relationship between morning/night type behavioral patterns and brain characteristics.

As a result, Dr. Norbury found that the night-type person had a large volume of gray matter in the gyrus , which is located on the inner side of the cerebrum called the anterior wedge .

'Meta-analysis and past studies have shown that gray matter is important for the brain functions needed to build social relationships. Also, the small volume of the anterior wedge is related to empathy, cooperation and cooperation. It has also been shown to be related. These are also linked to the idea that mornings are more likely to engage in social behavior than evenings.' 'It is not possible to measure how intimate one is However, it is possible that the amount of gray matter in the brain indicates this,' commented Dr. Norbury.

A 2013 study also showed that nighttime people were more likely to have narcissists and psychosis.
