At the age of 30, in China, it's not as good as middle age. I don't know how to fight. At this time, my brain has just reached the adult state. There is a certain truth in the ancient saying that I can stand at 30.
The human brain has its own 'developmental schedule'. According to the study, the brain is still undergoing great changes at the age of 18, and it is only about 30 years old that it reaches the adult state.
Now it's popular to say that you're 'old' after you're 30, and your brain 'often forgets'.
However, this is just a self assertion, isn't it? Other people's brains don't admit it - British scientists have pointed out that human brains reach adult state until we are about 30 years old.
Also recently, a European brain study showed that new neurons in the healthy brain continue to develop until people reach the age of 90. So, our bodies are really holding back our brains.
I'm 30 years old. I'm an adult
When we say that an adult is' mentally immature ', we should think that maybe his brain is not fully developed.
At a recent meeting of the Oxford School of Medical Sciences in London, Peter Jones, a neuroscientist at the University of Cambridge, UK, said that the research shows that the human brain does not mature very quickly, but is a slow and gradual process, and eventually reaches adulthood, almost to people's 30s.
His research suggests that people's brains are still undergoing tremendous changes at the age of 18, and they are also very vulnerable to mental disorders after 20, and this problem will be solved by the age of 30 or so.
The brain has its own 'development schedule', but the maturity of the brain affects people's behavior and mental state. Lack of a mature brain also means that the ability to control one's own emotions and communicate with others needs to be improved. Therefore, in a sense, it can also be called 'no adult'.
90. I'm not old
In contrast to the brain's' late ripening ', its' senescence' actually comes very late. New neurons continue to develop in healthy human brains until the age of 90, according to a new study.
Most of the neurons in the brain are present at birth. New neurons form in specific areas of the adult brain, such as the hippocampus, a process also known as adult neurogenesis. Previous studies have identified this phenomenon in rodents and other vertebrates. In addition, studies have shown that new neurons will integrate into human tissues. However, recent studies have questioned the degree of adult neurogenesis in human brain.
Scientists from the Autonomous University of Madrid, Spain - the Spanish Council for advanced scientific research, analyzed tissue samples of 58 subjects in detail. The results showed that although there was a certain degree of age-related decline, adult neurogenesis in the hippocampus could be observed throughout the life.
The study also found that there was a significant decrease in the formation of new neurons in the brains of Alzheimer's patients. The report was published in the British journal Nature & middot; medicine on the 25th.
Redefining brain and growth
Our new understanding of brain development is likely to have a significant impact on brain research and society in the future.
The 90 year old neurons, which are still developing, have overturned people's previous cognition. The scientists pointed out that the difference between their research and the previous research which did not detect adult neurogenesis may be due to the different methods used or the different quality of tissue samples. The new study takes into account factors such as tissue fixation technology and the delay between tissue acquisition and processing, and evaluates its impact on the quality of tissue staining, which is essential for the detection of new neurons.
Peter Jones analyzes this problem from the perspective of sociology. He said that most countries stipulate that even if they reach adulthood at the age of 18, this may not be the exact physiological "adulthood". Instead, they can exercise the rights of voting, drinking alcohol, mortgage and so on, and make the education, medical and legal systems work smoothly.
'what we really want to show is that defining a point in time for childhood to adulthood seems increasingly absurd. 'Jones explained,' this process is actually a slow transition, which will last for more than 30 years. '
In other words, there is no clear dividing line between childhood and adulthood. Regardless of the brain and cognition, we are always on the road of gradual maturity, moving forward slowly along the track of growth.
