Precuneus

Precuneus: structure and functions

The Precuneus is a region of the parietal lobe on the inner surface of both hemispheres of the cerebrum, located above and in front of the corpus callosum. This region of the brain plays an important role in various cognitive processes such as attention, visual perception, motor coordination, spatial perception and self-awareness.

Precuneus structure

The precuneus is one of the largest sections of the cerebral cortex and consists of several subregions. One of them - the upper part of the precuneus - is responsible for processing visual information and is involved in the formation of spatial maps. It also plays a key role in the mechanisms of awareness and self-awareness.

Another subregion of the precuneus, the inferior part, is associated with motor coordination and motor control. The third subregion is responsible for attention and concentration.

Functions of the precuneus

The precuneus plays an important role in various cognitive processes. For example, this area of ​​the brain is involved in processing visual information and forming spatial maps. It is also associated with the mechanisms of awareness and self-awareness, including the analysis of information about the body and one’s own position in space. Some studies have also linked the precuneus to social perception processes, such as perceiving the emotions and mental states of others.

The lower part of the precuneus is associated with motor coordination and movement control. This subregion of the brain plays an important role in complex motor tasks, such as playing a musical instrument or exercising in sports.

The precuneus is also associated with attention and concentration. Some studies show that activity in this area of ​​the brain increases when performing tasks that require high concentration and attention.

Conclusion

The precuneus is an important brain region that plays a key role in various cognitive processes such as attention, visual perception, motor coordination, spatial perception and self-awareness. Due to its functions, the precuneus has been the subject of interest for many studies that try to understand how this brain region works and how its functions relate to various cognitive processes.

The precuneus is a region of the parietal lobe, which is located on the inner surface of the cerebrum and is located between the callosum and occipital bodies. This area is responsible for processing information related to spatial perception, coordination of movements and orientation in space.

The precuneus consists of several regions, including the medial and lateral precuneus. The medial precuneus includes the posterior part of the inferior parietal lobule, and the lateral precuneus is located on the lateral side of the parietal lobe.

The precuneus contains various structures, such as the parietal lobules and gyri, which are responsible for spatial perception, spatial orientation, and movement. Also in this area are areas associated with the processing of visual information, as well as with the processing of auditory information.

The corpus callosum, which connects the right and left hemispheres, passes through the precuneus, providing communication between the two hemispheres of the brain.

Abnormalities in the precuneus can be associated with various diseases, such as Alzheimer's disease, stroke, multiple sclerosis and other neurological diseases. In such cases, there may be disturbances in spatial perception, motor coordination and spatial orientation, as well as problems with processing visual and auditory information.

The precuneus, also known as the Precuneus, is a region of the parietal lobe of the brain that is located on the inner side of both hemispheres. This is an important area of ​​the brain that is involved in various cognitive processes such as spatial orientation, pattern recognition, memory processing and problem solving.

The precuneus has several functions in the brain. It is responsible for the perception of information about the location of objects and objects in space, as well as for controlling the coordination of movements. The precuneus is also associated with attention and processing information we receive from the outside world. If this area is affected, there may be problems coordinating movement, and people may have difficulty using spatial skills

The precuneus, or precuneus, is the name given to the area of ​​the parietal lobe, which is located on the inner surface of the cerebral hemispheres of both occipital lobes of the human brain. This area is located primarily in the brain. It is believed to play a key role in controlling a person's self-identity. Through the formation of identification, each individual knows who he is and all his life aspects. A person lives in a society, in a society where there is often a need to define each other’s roles. This part of the brain helps here. Controlling one’s own behavior and place in the world are the tasks of which. Accordingly, deviation of the functions of this area leads to the fact that the individual does not distinguish the line between self-affirmation and self-destruction. Depending on how the areas in the brain work that correspond to responsibility and feelings of self-awareness in protecting one's own safety will vary quite a bit. This can become the basis for the occurrence of paranoid reactions and even psychosis.

The names of the forebrain section are largely different and none of them has been definitively accepted at present. For a general idea, we share the views appearing in various popular science sources: - Exakulus; - Hippocampus trigger organ (hippocampus (prefrontal skip-link));
