Zhang Meng of reporter of daily of science and technology like that
Popularity says him after striding 30 years old now " already old " , brain also " often forget a thing " .
Nevertheless, is this the view with act on one's own mouth only? Family cerebra can not admit -- British scientist points out, the person's cerebra achieves adult status, want us many years old.
Also be in the near future, a head of European considers to make clear, till the mankind reachs 90 years old of advanced age when, there still is new nerve inside healthy cerebra yuan in continuously development.
Look so, our body is the hind leg that pulled cerebrum really.

30 years old, we just grew up
Say an adult when us " intelligence is immature " when, should think, the cerebra that perhaps is him really still is done not have full-fledged.
On conference of academy of medical sciences of Oxford of near future London, peter Jones weighs the nerve scientist of British Cambridge university, research thinks human cerebra is not matured very quickly, however the process of a slow, successive, achieve adult status finally, want people many years old almost.
His research thinks, when 18 years old the person's cerebra still is in experience tremendous change, very easy also be fertilized is magical after 20 years old of age the influence of the obstacle, and this problem arrived 30 years old or so to be able to get settlement.
Cerebrum has him " development schedule " sure, nevertheless, the adult rate of cerebrum can affect the behavior of people and mentation. Without mature cerebra, the control force that also means pair of him moods, ability that communicates with other association remains to perfect. Because this comes up from some kind of meaning,say, also can say be " did not grow up " .

90 years old, we still are done not have old
With cerebrum " late-mature " opposite, its " consenescence period " also come very late actually. Newest a research points out: Till 90 years old when advanced age, there still can be new nerve inside healthy person head yuan continuously development.
The major nerve inside cerebrum yuan already existed when be born. In the specific head area of adult cerebra, be like sea horse body, can form new nerve yuan, this process also is called adult nerve to happen. The research in the past is already affirmatory, this one phenomenon produces in the meeting inside rodent animal and other vertebrate body. Additionally also research makes clear, new student nerve yuan can blend in human body organization. But, in recent years research produced degree to generate doubt to the adult nerve inside person head.
University of Spanish Madrid autonomy, Spain is advanced and scientific the scientists of research council labor the constituent specimen of 58 mankinds testee. Result discovery, although be put in the age dependency of certain level to drop, but the adult nerve inside aspect of person mind horse happens all one's life to be able to observe.
This research returns discovery, inside the head of patient of Aercihaimo disease, new nerve yuan form decrease apparently. The England that relevant report publishs at 25 days " natural · medicine " magazine.

Redefine cerebra and grow
We are right of cerebrum development process brand-new and cognitive, will consider probably produce major effect with the society to prospective head.
90 years old return the nerve in development yuan, had overturned people before acknowledge. The scientist points out, their research and past did not detect the research that produces to adult nerve exists difference, the likelihood is the method that uses because of place perhaps organize example quality to differ. New research considered to organize fixed technology and organization to get wait for an element with the defer between processing, evaluated its what to produce to affect to organizing coloring quality, and this quality actually new to detecting nerve yuan crucial.
Peter Jones analysed this problem from sociological level. He states major nation sets 18 years old to calculate enter year after year, this is not exact physiology probably go up " grown " , however can loan of voting, drinkable alcohol, mortgage waits exercise a moment the right, also make education, medical treatment and legal system movement smooth.
"What we want to explain truly is, define a time to select this issue for manhood for childhood change, look absurder and absurder, " the explanation says Jones, "This process actually a slow transition, can last probably 30 old. Can last probably 30 old..
In other words, there is apparent boundary between childhood and manhood. No matter cerebrum is mixed acknowledge, we go in from beginning to end mature gradually on this road, along the orbit that grow slowly forward.
