Road blindness is it really born?

  After being spoiled by various navigations, the young people in the north, south, east, and north were originally confused, and more people became road silly. However, the exaggeration of the real road idiot still amazes many people. Is this real road idiot or pretend, is it that the brain is not good?
  Didi or meet up with friends on weekends. When confirming the location, you can only rely on the names of nearby buildings to determine where you are. If there are no obvious buildings around, you can only say that you are beside a tree, under a cloud.
  When I was in college, I had a female classmate who came out of the lecture theatre to go to the toilet during the break. After she walked out of the toilet, she often couldn’t find her way back to the classroom.
  Zhang Ailing described her road idiot in “A Dream of Genius”: “After living in the same room for two years, I am still at a loss to ask me where the electric bell is. I take a rickshaw to the hospital every day for injections. I still don’t know each other for three months. That way.”
  So, what is going on with Lu Chi? Is it born?
  Since 1970, through experiments on mice, we have confirmed that mammals have three types of cells related to orientation. There are cells that distinguish the direction of north and south, the cells that are responsible for understanding the location of their own positioning, and the grid cells that are responsible for forming the concept of space.
  In short, there is both a compass and a coordinate system. After combining the two, you must have the comprehensive ability of “Can you understand your own positioning?” Of course, remembering the way also requires a certain visual memory.
  After the three kinds of cells are combined, people with a particularly good sense of direction will build a virtual map that looks very advanced in their brains, and they can also rotate 90 degrees clockwise and counterclockwise, or flip it axisymmetrically.
  One of these types of cells is not well developed, which may affect the overall way recognition ability.
  However, even if it is due to genetics, growth environment and other reasons, some of these three types of cells do not develop well, but in order to identify the direction, everyone will develop their own strategies.
  For example, if you can’t distinguish between north and south, you can improve your observation. In nature, the position of the sun and the growth of leaves can be used to judge the north and south. In the city, the north and south can also be judged by the orientation of the balcony in the residential area and the distance between the buildings.
  If you can’t create a three-dimensional map of your brain, then memorize the mobile phone map and apply it directly when you need it. Or simply remember the specific coordinates, such as a duck neck shop and turn left.
  Anyway, if there is really no sense of direction, and various cells related to direction are underdeveloped, you can still “remember” the matter of recognizing the way. The memory depends on the hippocampus.
  The University of Michigan conducted a memory test on twins. Researchers recruited more than 500 pairs of twins, asked them to look at the faces, locations, objects, and words on the screen, and then performed MRI scans of their brains.
  As a result, when recalling faces and locations, the brain activities of identical twins showed a high degree of similarity, but when recalling words or common objects, they were different. This indicates that humans’ ability to recognize faces and places may be greatly affected by genetics. So the sense of direction does have an innate element, and acquired training is only part of it.
  For example, some children have been to the park or grandfather’s house once, and the adults can find them next time. There are many preschoolers with a good sense of direction.
  In addition, the sense of direction may indeed be related to gender. Men have a better sense of direction and greater spatial ability than women.
  Some people say that this is related to the evolution of Homo sapiens. In the fishing, hunting and gathering society, men need to travel long distances to hunt in places far away from the village, which requires them to be able to find a way home. Women are mainly responsible for collecting near home.
  But researchers have also studied other animals. It seems that whether it is mammals such as mice or molluscs such as squid, males always have a better sense of direction than females.
  In addition, after a woman drops a drop of androgen under her tongue, her test scores for sense of direction and sense of space will also increase.
  Based on this inference, the gender difference in the sense of direction may only be a harmless by-product of evolution, rather than through natural selection.
  Although in the real world there are more girls who are crazy about roads, it does not rule out some people’s smashing. Anyway, I don’t recognize the way, just follow the navigation! Or just walk with the people around you.
  After all, smart people can’t be smart everywhere. Some harmless shortcomings, there is nothing wrong with neutralizing your perfect self.
  However, the majority of road idiots can understand the fact that if you really want to recognize the road, even if the sense of direction is inherently bad, it is completely okay.
  When it comes to stereotypes, in addition to “bad sense of direction”, women also have a label of “good memory”, and road recognition has a lot to do with memory in addition to cells related to the three directions.
  Compared with men, women prefer to mark landmarks when recognizing roads, such as hot pot restaurants, milk tea shops and various shopping malls. Living in the city, this may be a more practical way to find the way.
  In 2004, researchers found that taxi drivers in London have a larger hippocampus area, which shows that their brains have undergone extensive long-term training in order to remember the road, understand the location and plan the route. This has achieved remarkable results, and the taxi driver has become a humanoid GPS for walking in London.
  However, the proportion of road silly pupils who get on and off the school bus every day has increased significantly.
  In short, the sense of direction may be innate, but it does not affect the acquired mastery of way recognition skills. Many road idiots may just be lazy.
  But now that GPS and navigation software are so developed, not recognizing the way has little impact on life. But some people can’t even understand the navigation map. For them, I just want to say that we can’t completely give up treatment.
