In the impression of average person, dot always can accept new knowledge immediately it seems that. Where is the whether is put in certain science rear basis of this kind of phenomenon? The United States " science " magazine network introduced · of Jeff of Washington university scientist newest discovery of Lixiteman, made oneself explanation to this one phenomenon.
Their experiment passes the small rat that gene project handles to seeming a kind. The nerve cell of this kind of small rat may convey a kind to be able to give out the protein of maize fluorescence. Researcher films continuously with camera a few months, the fluorescence in the photograph can reflect the mobile condition of each place secondhand. We know, nerve cell can be extended grow long “ tentacle ” , use have contact with other nerve cell, neurology home calls this kind of structure “ axis dash forward ” . Study the result makes clear, the small rat of a month, the axis that has 70% dash forward meeting left and right sides swings, and after small rat grows 4 months, this scale can fall 10% . Axis dash forward swing lesser, explain the connection between nerve cell jumps over stability. And our memory results from the connection between nerve cell, turning over be used to of go back to school and process is the process that aggrandizement contacts this kind, and oblivious process is as contrary as this.
Experts explain the change that nerve of different age level contacts with the analogy of a figure. The connection of cell of nerve of childhood small rat resembles a mobile telephone, it is very easy to each other join or be interrupted, but signal is not quite clear. And the connection between cell of the nerve after small rat is grown more and more the elephant secures a phone, take time of laid electrical wiring is arduous, but communicate quality is very good however.
The expert thinks, the research of the person such as Lixiteman makes clear, always be being built ceaselessly in each level nerve cells of life or sever each other connection, it is its degree differs only. From which, we also can understand better, why child learning new knowledge is faster, and adult is more firm to intellectual control.
