British scientists point out that the human brain reaches adulthood and is about 30 years old. At the same time, a brain study in Europe showed that until the age of 90 years old, there are still new neurons in the healthy brain. So it seems that we really underestimate the brain.
30 years old, I am an adult
When people say that an adult is “immature”, he should think about it, maybe it is really his brain is not yet fully developed.
At a recent 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 human brain is not maturing very quickly, but a slow, gradual process that eventually reaches adulthood and is about 30 years old. .
The study believes that when the age of 18, people’s brains are still undergoing tremendous changes. After the age of 20, they are also very susceptible to mental disorders, and this problem will be solved by the age of 30.
The brain has its own “developmental timeline”, but the maturity of the brain affects people’s behavior and mental state. Without a mature brain, it means that the control of one’s emotions and the ability to communicate with others need to be improved.
90 years old, I am still not old
In contrast to the “late maturity” of the brain, its “aging period” actually came very late. A new study shows 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 certain brain regions of the adult brain, such as the hippocampus, new neurons are formed. This process is also called adult neurogenesis. Studies have also shown that newborn neurons are integrated into human tissue. However, recent studies have questioned the extent of adult neurogenesis in the human brain.
Scientists from the Autonomous University of Madrid in Spain and the Spanish Advanced Scientific Research Council analyzed the tissue samples of 58 human subjects in detail. It was found that although there was a certain degree of age-related decline, adult nerves in the human hippocampus were 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
A new understanding of the brain’s developmental process 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. Scientists point out that the difference between their study and those that have not detected adult neurogenesis in the past may be due to differences in the quality of the methods or tissue samples used.
Peter Jones analyzed this issue from a sociological perspective. He said that most countries require 18 years of age to enter adulthood. This may not be the exact physiological “adult”, but the right to vote, mortgage, etc., and to make the education, medical and legal systems work smoothly.
“What we really want to explain is that it seems more and more ridiculous to define a point in time for the transition from underage to adulthood.” Jones explained, “This process is actually a slow transition, probably lasting 30. for many years.”
In other words, there is no clear dividing line between underage and adulthood. Regardless of the brain or cognition, we are always on the path of maturity, moving slowly along the path of growth.
