Brain lobes

The human brain and every function present in our brain wolves. In them, our conscience is installed, language is articulated, memory is regulated, emotions are regulated and innumerable other processes occur.

The brain is something beyond a simple accumulation of neurons. In fact, even the classical metaphor we use comparing this organ with a computer seems to be short. The brain and each of its structures are the direct result of our constant interaction with the environment.

"The eye absorbs ... the brain produces forms".
-Paul Cézanne-

We are what we see, what we feel, what we experience and how we react to each stimulus and circumstance. The brain is "framed" and with each experiment are precisely the cerebral lobes that further facilitate each process according to its characteristics. Identifying them and understanding each of the processes that they usually perform will help us to have a richer and more complete vision of this body.

The brain wolves and their functions

When we think of wolves in the brain, we can make the mistake of imagining a series of separate or differentiated structures. Well, it is important to emphasize that there are no intermediate barriers and the four main areas that form the brain lobes always work in harmony, connected and share information constantly.

On the other hand, the fact that each brain wolf has a series of characteristics does not mean that each structure controls almost "exclusively" a certain task. Many activities and processes overlap through different regions of the brain.

Thus, the functioning of one region can not occur effectively without the presence of another. Therefore, sometimes the brain damage caused in a specific area can be compensated with other regions that can perform greater or lesser efficiency.

In addition, sometimes even the researchers themselves argue with each other about the exact point at which one wolf begins and another ends. On the contrary, we can almost say with the naked eye are the two hemispheres: the right and the left.

From here we learn that each of the four lobes that form the brain through the two hemispheres. So neurologists speak with more precision the left frontal lobe, the right frontal lobe, etc. Let's go, therefore, the characteristics of each lobe of the brain.

Frontal Wolf

The frontal wolves are the very essence of the result of our evolution. Located in the front of the head, just below the frontal bones of the skull and near the forehead, they make up the most refined region of our brain, the one that took the most time to evolve and appear. Thus, among the various tasks you can perform, are the following:

The production of speech and language thanks to the area of Broca, an exceptional region that allows to translate thoughts into words.

In addition, the frontal lobe is characterized mainly by its cognitive processes, the sophisticated executive tasks that allow to plan, focus attention, remember long-term information, understand what we see, regulate emotions, etc.

In the same way, the frontal wolf also allows us to understand and react to the feelings of others. We speak, of course, of empathy.

Regulation of motivation and the search for rewards: most of the neurons sensitive to dopamine in the brain are in the frontal lobe.

Parietal Wolf

The parietal wolf is on the occipital wolf and behind the frontal lobe. Its functions are multiple, but if there is anything that distinguishes this area of the brain is its role in sensory perception, spatial reasoning, movement of the body and our orientation.

It is also in this area that sensory information relative to most of our sensory organs is captured. Where the sensation of pain, physical pressure and temperature is processed and regulated, etc.

On the other hand, thanks to the parietal zone, we can understand the nature of numbers. Its relation with mathematical competences is, therefore, very relevant.

Occipital wolf

Among the 4 cerebral wolves, the occipital is the smallest, and at the same time the most interesting. It is located near the nape of the neck and does not perform a specific function. It is almost like that route of passage through which most of our mental processes are organized and connected.

Participates in the processes of perception and visual recognition.

The occipital wolf also has a fundamental importance in everything related to our sense of vision. In fact, your cortex integrates several visual areas, such as the one that detects the patterns, processes that information and sends it to other areas of the brain.

It helps us differentiate colors.

It also participates in the development of emotions and thoughts.

Temporary wolves

Attached almost at the temples and on both sides of our brain, it is the wolves that also regulate a large number of processes. As we have seen so far, it is very complicated to associate each of these structures with a single specialized function. All depend on each other, all are connected and favor the perfect harmony in which the temporal wolves also perform essential tasks:

It helps us recognize faces.

They are also related to the articulation of language and the understanding of sounds, voices and music.

It facilitates the balance.

Participates in the regulation of emotions, such as motivation, anger, anxiety, pleasure ...

The lobular insula

Our brain is organized into four wolves. From the neuroanatomical point of view, there are many studies that speak of a fifth region. We speak of the insula, a wolf hidden just below the temporal, frontal, and parietal wolves. It is a very recondite area with complex access located between several blood vessels and arteries.

Its functions are not known exactly. However, different processes and alterations have been observed in patients with epilepsy and who present different damages in that structure. She was to participate, for example, the sense of taste, control and somatosensory visceral perception, and was also related to our emotional processes by integrating the limbic system.

Functions of the brain wolves

As we can see, the brain wolves are a fascinating map of processes and connections where it is very difficult to establish functional limits. Perhaps of all, the most interesting is the frontal lobe, to take charge of the executive functions that assume, without a doubt, a great advance in our species. In fact, it is based on processes as important as the planning or control of stimuli. In any case, there is something that we can not forget either: our brain continues to evolve ...
