American scientists have found significant differences in the brain structures of boys and girls during their growth. In this respect informs TASS.
A sample of 8.9 thousand children aged 9-10 was compiled to conduct the study. Parents were asked to bring their children for periodic brain scans using an MRI machine. Scientists were interested in changes in the structure of gray and white matter in the brain and gender differences in these changes. As a result, it was possible to confirm the long-standing hypothesis that the developmental pathways of the male and female brain are significantly different. In particular, significant differences were noted in the structure and speed of development of the passive mode network of the brain, which plays an important role in the functioning of the brain during inactivity.
As a rule, girls were characterized by a higher density of connections between neurons in this network, as well as an increased density of white matter in the areas of the brain associated with it. According to scientists, this reflects the fact that the brains of boys and girls mature faster than the nervous systems of boys and girls, on average. Scientists have identified similar patterns when comparing the degree of “adulthood” of the brain and the level of intellectual development of children.
Discovering these differences in the nature of the brain development of boys and girls explains the existence of age-related differences in the cognitive abilities of schoolchildren and girls.
