N or want to be ominous, but surely you have noticed or will notice if you do not you pass forty, how to Over time your legs and your brain have become more lazy. And, however much we care, our brains grow old and die, so that the foot still holding the gun must make a daily effort greater than when they were younger and were more outings.
However, you also you will have noticed that you are still capable of performing many complex tasks as well or even better than when you were a twentysomething. This is especially evident when it comes to tasks that probably learned long ago and have been held fast with an intensive and repetitive practice.
The reason for this resistance is partly due to that practice, areas of the brain responsible for a particular motor skills, perceptual cognitive or expand. To be more responsible area, every little brain damage associated with aging does not affect the whole area, so that the skills acquired will not be lost forever because neurons survive in this vast region that will handle the job.
Another justification has to do with that practice reduces the metabolic demand for oxygen by neuronal tissue responsible for the task. Thus, although age diminishes the oxygen supply to our brain, we can do the job with a lower supply, provided that it is a well established skill or competence. Ie, increases the efficiency of these neurons either trained, they require little fuel to do their job.
The combined effect of these phenomena effectively counteract the consequences of certain diseases or simply aging neuronal have for our cognitive performance. Despite the age, with few exceptions, do not lose our expertise at executing those tasks well established domain. However, that does not happen with new competencies and skills acquisition, which still requires good oxygenation and will be located in a small area of \u200b\u200bthe brain. In this case we must work harder and practice more than when we were younger until competition is well established, and increase the neurons involved, which also consume less O2.
is, like maintaining a good physical tone in old age requires more effort than in youth, learning new tasks require more practice to achieve a consolidation that will stand the test of time. Otherwise we will see how these newly learned skills evaporate generating an intense frustration, as we will have to start over.
