Nowadays, when I am 30 years old, I say that I am “already old” and my mind is “often forgetting things.” However, is this just a statement of self-assertion? People’s brains don’t recognize it – British scientists point out that people’s brains reach adulthood and are in their 30s. Also recently, a brain study in Europe showed that new neurons still develop in healthy brains until humans reach the age of 90. It seems that our body is really dragging the hind legs of the brain. 30 years old, I am an adult When we say that an adult is “immature”, you should think about it, maybe it is really that his brain is not yet fully developed.
At a meeting of the Oxford Academy of Medical Sciences in London, Peter Jones, a neuroscientist at the University of Cambridge in the United Kingdom, said that the study concluded that the human brain is not maturing very quickly, but rather a slow, gradual process that eventually reaches adulthood and reaches people 30. When you are a few years old. His research suggests that at the age of 18, the human brain is still undergoing tremendous changes, and after the age of 20 is also very susceptible to mental disorders, and this problem will be resolved by the age of 30. 90 years old, I am still not old In contrast to the “late maturity” of the brain, its “aging period” actually came late. A new study points out that until the age of 90, there will still be new neurons in the brain of healthy people. Most of the neurons in the brain are already present at birth.
In the specific brain regions of the adult brain, such as the hippocampus, new neurons are formed, a process also called adult neurogenesis. Past research has determined that this can occur in rodents and other vertebrates. In addition, studies have shown that newborn neurons are integrated into human tissue. However, recent studies have raised questions about the extent of adult neurogenesis in the human brain. Scientists in Spain analyzed the tissue samples of 58 human subjects in detail and found that although there is a certain degree of age-related decline, the adult nerves in the human hippocampus can be observed for life.
The study also found that the formation of new neurons was significantly reduced in the brains of patients with Alzheimer’s disease. Redefining the brain and growing Our new understanding of brain development is likely to have a major impact on future brain research and society. Neurons that are still developing at the age of 90 have subverted people’s past perceptions. Peter Jones analyzed this issue from a sociological perspective. He said that most countries stipulate that even if they are 18 years old, they may not enter the adulthood.
This may not be the exact physiological “adult”, but they can exercise the rights of voting, drinking alcohol, mortgages, etc., and also let the education, medical and legal systems work. Smooth. “What we really want to say is that it’s getting ridiculous to define a point in time for childhood to become adult.” Jones explained, “This process is actually a slow transition that will last for more than 30 years. ” In other words, there is no clear dividing line between childhood and adulthood. We are always on the road of maturity and slowly moving forward along the growth track.
