Brain structural (left) and functional plasticity (right) in different PA levels
Prepuberty and puberty are critical periods in the brain that develop rapidly until it becomes a highly structured and functionally specialized brain. And the plasticity of gray and white matter continues into the 30th year of life. Previous studies found that PA can significantly promote the development of brain function, which is related to improving cognition function and academic performance.
In this study, PA shows a positive relationship to the left postcentral gyrus's surface area and an inverse relationship to the right inferior temporal gyrus.
