Myths and trues about the BrAiN


Hello everyone! This week I’m going to talk about a lecture very interesting made by Dr. Pedro Maldonado, teacher of physiology of the Faculty of Medicine of University of Chile. He spoke about the myths and trues about the brain.
The first myth which he said was “the human brain is different to the other animals” this is false, because the human brain have the same structures that the animal brain (we are animals too), the only difference is that the human cerebral cortex is longer and have more neurons, for this reason the human brain have more furrow.
Other myth is “for each activity we use a part of the brain”, it’s wrong, because in the brain activate a lot of parts, in fact, when we don´t make anything, the brain have activity too.
Many people believe that the “brain is like the computer”, this is wrong too, because the computer can make one thing every time and the memory is store in one part, on the other hand, the brain is more complicated, it can make much thing at the same time and the memory is store in a lot of parts.
Other myth that he said is “we use the 10% of the capacity of our brain”, this is false, because we use all the capacity of our brain. Our brain is plastic, in other words, it can change, for this reason while more we use our brain this have more connections.
And the last myth that he said us was “the brain reproduced the world faithfully” it’s false too, because the brain builds its own world, for that reason we have different point of view and we interpret the thing of different way.
Know this thing is very important because we are controlled for our brain, the organ more complex of our body, and this explains why we can make a lot of things, and why we are and think so different. Know these topics help us to understand that our patients will are very different: a pregnant will think and will feel the pain different that other pregnant, so we should treat them of form personalized.
