Neurogenesis and Physical Activity
The article under analysis published in 2017 is entitled “For your brain’s sake, keep moving.” This article is closely related to the Nervous system and neurons topic as it dwells upon the way physical activity can influence neurogenesis. Neurogenesis is the process of the creation of new brain cells, which is critical for all mammals, including humans. Reynolds (2017) reports the results of several studies that involved laboratory mice whose neurogenesis was measured. It was found that physically active mice were allowed to run on the running wheel in their cages, producing more new neurons with longer dendrites, as compared to inactive mice. The author stresses that this process was more apparent in the brain zone responsible for memory (Reynolds, 2017). The value of the reported study was its focus on the quality of new neurons as older studies had shown that physical activity led to the production of more neurons.
The article provides insights into the way the nervous systems of mammals develop throughout their life and the factors affecting this process. Importantly, the author adds that researchers admit that they are still unaware of the effects of this enhanced neurogenesis in mice (Reynolds, 2017). They do not know whether new neurons improve animals’ memory or the way they think. It is also emphasized that the laboratory experiments were conducted on mice, so it is early to state that the same processes take place in people’s brains. However, it is added that some studies involving people have been conducted, and they suggest that physical activity improves people’s brain activity and reduces the risk of developing dementia. The article ends with the statement that physical activity improves people’s health. Hence, to remain healthy (physically and mentally), it is essential to be physically active.
