Abstract

pyramidal neurons are important neurons in the cerebral cortex, With perfect function, sports, as a
purposeful activity to increase the input of various kinds of information to human body, will inevitably cause the
changes of the fine structure of the central nervous system, including the cerebral cortex, and the number of
dendritic spines is related to the development of human intelligence. Therefore, this paper puts forward the
research on the influence of sports on the number of dendritic spines in the cortical vertebral cells of mice. In
this paper, the method of control experiment was used to study. By setting up the control group and the exercise
group, we observed the number of dendritic spines in the cortical vertebrae of mice. The results showed that the
number of apical, lateral and basal dendritic spines in the pyramidal cells of the somatosensory cortex in the
exercise group was higher than that in the control group, in which the number of apical, lateral and basal
dendritic spines in the exercise group increased by 19.1%, 29.6% and 18.2% respectively. The experimental
results show that various forms of exercise can increase the number of dendritic spines in many pyramidal cells
in each layer of human cerebral cortex. Therefore, physical exercise can improve the function of cerebral cortex
and enhance human intelligence.
