If you look at the brain from above, it is immediately obvious that it is divided into two from front to back. There are, in fact, two hemispheres, as if we had two brains in our heads instead of just one. Of course, those two halves are intimately linked by an arc of white substance, called the corpus callosum.

Although both human hemispheres are opposite, they are not the inverted geometric image of each other. Functional differences between hemispheres are minimal and only in a few areas have differences in operation been found.

Normally, language, mathematics and logic reside in the left hemisphere. Law deals with spatial orientation, face recognition, body image and the ability to appreciate art and music.

Cerebral cortex specialization

Researchers have discovered that both parties have some specialization. The left hemisphere is related to the right part of the body (normally), and the right hemisphere is related to the left part of the body. In addition, it is the left hemisphere that normally has language, and seems to be primarily responsible for similar systems such as mathematics and logic. The right hemisphere has more to do with things like spatial orientation, face recognition, and body image. It also seems to govern our ability to appreciate art and music.

There are many interesting anecdotes that come from his research. For example, it turns out that, although the left hemisphere has language, it is quite bad for drawing. The right hemisphere, which controls the left hand, could draw quite well.

Logic and intellectual activities preferably use the prefrontal cortex

The corpus callosum maintains communication between the two halves of our brain. Related to the different areas, it has been said that language and logic give the individual greater capacity to adapt to the environment. The most specialized areas in language are Broca and Wernicke's (these areas are found in most of the individuals in the left hemisphere) and the areas most involved in the logic and intellectual activities are mainly located in the prefrontal cortex.

Cerebral cortex specialization

Recent research indicates that exercise is beneficial to improve brain function and mood and increase learning. By increasing the ability of blood cells to absorb oxygen, Exercise improves muscle, pulmonary, cardiac, and also brain functions. Oxygen is a vitally important element in the functioning of the brain, and therefore, for learning and memory. Oxygen is transported by the blood, but if it is enhanced by physical exercise they can increase brain capacities and promote neuroplasticity, besides helping to avoid stress.

That is why physical exercise in the classrooms should have more support from the educational institutions and the educational community. Physical education should accompany each and every one of the learning processes.

In addition, physical exercise is in turn beneficial for the socialization and control of emotions and even, as has been shown in numerous studies, can help reduce the level of aggressiveness and depression in people (throughout the entire lifetime).
