The fact that between the female and male brainsthere are structural differences, scientists have known for a long time. So, in 2017, researchers from Amen Clinics studied 20,000 photographs of the brain and found out that the female brain is much more active than the male one. It turned out that with greater activity, the female brain also retains its youth longer. This statement was proved by researchers from the University of Washington School of Medicine, having carefully studied positron emission tomography scans of 205 people.
The discovery was made during the speed assessmentmetabolism in the brain of women and men. Two hundred photographs captured the brains of representatives of different sexes aged from 20 to 82 years. In particular, scientists paid attention to the rate of consumption and oxidation of glucose, oxygen absorption and blood flow in 79 sections. When metabolic rates were compared with the ages of study participants using the random forest machine learning algorithm, it turned out that the difference between the real and metabolic age of people ranges from several months to two years.
To get more accurate data, scientists decidedrun the algorithm, dividing the data of women from men. It turned out that the metabolic age of men's brains is 3.8 years longer than that of women. It is noteworthy that age did not depend on the amount of proteins called beta-amyloids, which are considered the cause of dementia and the development of Alzheimer's disease.
The study proved that the female brain remainsquite young even in old age due to minimal changes in the metabolic process. In the future, scientists intend to find out the consequences of such differences and, possibly, increase the sample of data in order to obtain larger-scale results.
