The brain structure is actually "different for men and women" February 21, 2019 Source: Science and Technology Daily Author: in chawol There is an old saying in China: a female junior, holding a golden brick, if the woman is 3 years older than the man when she is married, it will herald a happy life after marriage. Although this is only a folk slang, a new study uses scientific data to tell people the mystery of "3 years old." Recently, researchers in the United States have found that the brains of adult women are about three years younger than the brains of men of the same age. What scientific reason is the result of this scientific research based on? At present, we have explored the gender differences in the human brain in terms of structure and behavioral cognition. What will these differences mean? Recently, the Science and Technology Daily reporter interviewed Li Jun, an associate professor of the School of Life Science and Technology at Xidian University. Metabolic angle female brain is younger “This study evaluates the 'age' of the brain by testing the metabolic levels of the brains of male and female volunteers.†Li Jun told reporters that the metabolism of the human brain will gradually slow down as the physiological age increases, and the process progresses slowly. There may also be gender differences in the degree. Researchers at the University of Washington School of Medicine used positron emission tomography (PET) to scan the brains of more than 200 volunteers aged 20 to 80 to obtain metabolic data from their brains. "The brain will inevitably consume glucose and oxygen when it is running." Li Jun further introduced that the essential substances of metabolism, glucose and oxygen, are labeled with short-lived radionuclides and injected into volunteers. These metabolically naturally consume these labeled Glucose and oxygen, researchers then use PET technology to scan the degree of aggregation of radioactive materials in different brain regions, thus revealing the metabolic activities in the brain. “These features can be reflected in the image, just like doing CT.†It is reported that the researchers used machine learning algorithms to establish a predictive model between experimental data and age. The results show that from the perspective of metabolic level, the female brain is about 3 years younger than the male brain of the same age, and the difference is in their 20s. It has already begun to appear. In Li Jun's view, this study explains to some extent why there is a bias in cognitive and comprehension between peers. Perhaps because women's brains are younger, if the woman is older than the man in marriage, the brain maturity of both sides may be more similar, and the brain's cognition, understanding, and way of thinking may be closer. "In order to understand more in daily life, avoid some contradictions and disputes." Differences in brain structure lead to differences in cognitive behavior The human brain not only has gender differences in metabolism, but also “men and women are different†in brain structure. According to Li Jun, men's brain capacity is often greater than that of women of the same age. The quality of the cerebral cortex is usually greater than that of women, but the thickness of the cortex is thicker. Some scholars have analyzed this problem in more detail in published papers: the study found that the gray matter volume of some areas of the frontal, parietal and occipital regions of women is significantly larger than that of males; female hippocampus, cingulate gyrus and carcass are higher. The anisotropy indicates that the degree of myelination in these areas of women is higher than that of men; the information transmission efficiency of female brain structure is more efficient than that of men. "Recent studies have shown that men's right brain is more developed, while women are better at using the left brain. These differences are also reflected in human behavior and cognition." Li Jun said that men have higher spatial recognition than women. The ability to know and the ability to think logically, while women are better than men in verbal ability, such as verbal fluency, verbal memory. "On the other hand, our research on the individual differences in human physiological structure including the brain is also laying the foundation for precision medicine. The difference between men and women may be the first step in realistic precision medicine." In the future, the ultimate goal of medical treatment must be personalized medicine, that is, each person should adopt a personalized and precise treatment plan for his or her physical condition. Taking the adult cold as an example, the current amount of drug treatment is the same, and men and women do not treat it differently. However, "this is unscientific." The immunity of different genders and even different individuals is different, and the sensitivity of the human body to drugs is no exception. Therefore, it is necessary not only to prescribe the right medicine, but also to vary from person to person. “Finding the difference between people and people is not only aimed at achieving precise medical care, but also helping to optimize people's enrollment and work.†Li Jun emphasized.
