You did not know! We are able to create new neurons even adults.
This discovery is relatively new, as we thought we were born with a certain "neural bank" which was decreasing with the pbadage of time, but we were never able to expand it . However, the latest discoveries in neuroscience demonstrate this belief.
Our brain is plastic: we can create different connections and even, in some areas, such as the hippocampus, new neurons can be born, according to Professor Terry Sejnowski of Salk Institute of Biological Studies. Thus, we have room for maneuver, regardless of age. Good news!
The hippocampus has the shape of a seahorse and is one of those responsible for our memory and our spatial ability. Research on the hippocampus began with rodents: several images were shown to rats, which had to differentiate.
Well, when rodents learned to distinguish them after practice, it was found that new neurons had been generated in their hippocampus. . Curiously, if the animal stopped this exercise, the young neurons disappeared. And if she resumed the activity, they reappeared.
So we already have an important clue: a repeated practice allows to generate new neurons in our hippocampus . But if we had to decide what activity really allowed us to keep our brain young, Sejnowski did not doubt it. Sport is the best gift we can get or the best anti-aging medically for our body mbad.
Exercises
We knew that practicing sports was a way to take care of our body and reduce stress through hormonal dances. which are activated by dopamine, serotonin and norepinephrine. But more recent research shows that exercise also improves the secretion of cerebral neurotrophic factor (which positively influences memory and a more positive mood) and allows the birth of new neurons in our hippocampus.
Despite its advantages, there does not seem to be any excessive sensitivity in the link between learning and sport . In fact, physical exercise in school is often perceived as a María without much value. But we were wrong. Educating children and adults in sport not only helps our bodies to be better and healthier, but also helps our brain to stay younger and able to generate new neurons. And as Sejnowski summarizes, "The gym and recreation are the most important elements of the program."
So, if our brain is able to generate new neurons with sport, what must we do to make this happen? Once again, the frequency. As the experts suggest, we must practice three times a week with a minimum duration of 30 minutes. Therefore, think of yourself.
What is your relationship with sport? If it's not a constant love, remember the physical and neural benefits. Look for a nice exercise for you, a group of friends, if you have trouble encouraging yourself alone. and put on your shoes. Your seahorse will thank you.
