A good environment can make people smarter

      We know that some people are born to be smart, some people are the result of the day after tomorrow efforts. Congenital not by their own decisions, then the day after the smart to rely on what to achieve it? Dutch scientists have recently found that there will be similar symptoms of mentally handicapped mice placed in a strong signal stimulus environment, can enhance the function of nerve cells. If this method is also effective for people, will be used to treat certain mental disorders.

      Among human intellectual disorders, the most common is called a fragile X chromosome syndrome. The patient's X chromosome has a gene defective, resulting in learning and memory is low, in the face of strangers feel anxious. According to the United States, "Science" magazine reported that the Dutch scientists to the same gene defects in the experimental mouse for the study, these mice have similar learning disorders with human patients. Scientists have analyzed the prefrontal zone of the brain of the experimental mouse and the ability to store information in the region for longer periods of time (more than a few minutes). Gene defects make the dendritic spines on the brain of the experimental rats, and the dendritic spines are the thorny processes at the end of the nerve cells, which are the main parts of the contact between the nerve cells. Too long dendritic spines make it difficult to exchange calcium ions between nerve cells, and calcium ions are the key channels for signaling between nerve cells.

      Scientists put the mentally handicapped experimental mouse on a lot of toys, rotating wheels, channels and other facilities in the environment, so that it receives a strong environmental signal stimulation. After two months, the dendritic spine of the prefrontal cortex of the rats became normal. This means that the calcium ion exchange between neuronal cells is enhanced and the ability of the cells to store signals for a long time is restored. However, the method in the human body whether the same effect, still need further verification.

      From medical practice, especially in the treatment of patients with brain dysfunction in the process of discovery, continuous stimulation and functional recovery for patients with a good therapeutic effect. If the use of people in the process of growth can draw such a corollary, a good environment, including a good learning environment and a good living environment can make people become more intelligent, which is why the city's children than rural children is relatively clever the reason. The brain is a complex network memory composed of innumerable neurons, its memory is completely different from the computer's digital memory, but a relatively infinite expansion of the network system, and stimulate the brain to expand memory is to continue to accept the new Knowledge to stimulate.

      With the development of science and technology, people's brains are more and more developed. Modern IQ is at least a lot higher than the IQ of a thousand years ago, and this is also due to changes in the environment. Of course, changes in the environment will also bring harm to our intelligence, excessive stimulation will make some of the functions of the brain degradation, which is contemporary in some ways worse than the ancients one of the reasons.
