Occipital lobe [L. Occipitalis, Pna, Jna; L. occipitalis (Cerebri), Bna]

The occipital lobe (lat. L. occipitalis) is one of the lobes of the brain located posterior to the parieto-occipital sulcus. It is part of the occipital lobe of the brain and occupies most of the posterior surface of the brain.

The occipital lobe has a complex structure and consists of several zones that perform different functions. One of the key areas of the occipital lobe is the occipital cortex, which is responsible for processing visual information and pattern recognition. Also in the occipital lobe is the visual center, which is responsible for the formation of visual perception and processing information coming from the eyes.

In addition, the occipital lobe plays an important role in processing auditory information and determining the direction of sound. A special area of ​​the brain called the auditory center helps her in this.

Also in the occipital lobe there are centers responsible for eye movement and coordination of movements. This allows a person to navigate in space and perform complex movements.

Thus, the occipital lobe is an important element of the human nervous system and plays a key role in shaping our perception of the world around us.

The dorsal occipital lobe (L. ossipalis, BPNA, JNA L. ossipalis (cerebrium), BNA) is one of the areas of the brain located on the back side of the head. It is located between the anterior lobe (LPH s, BSA, SPNA) and the parietal lobe (LTP s, LPH. Between the L.ossipalis and LPH s/LPH there is the cingulate gyrus (PPC), and an even more concave strip with

What is the occipital lobe?

The occipital lobe, part of the cerebral hemispheres of mammals, is associated with the functions of vision, hearing and control of motor functions on the opposite side of the body.

How is the occipital lobe determined in general topographic anatomy? It is believed that the lobes of the superior frontal and hindbrain completely characterize the structure of the brain as a whole. A feature of the structure of this region is the clear delineation of the forebrain, hindbrain and pons into lobes in humans. That is, the visual, visceral and pontine sections are distinguished.

Optic lobe – consists of the occipital lobe of the brain, or “first lobe.” This area is a continuation of the optic radiation and is located at the base of the bony protrusions - the parietal and occipital tuberosities. The occipital lobes are separated from the temporal lobe by the olfactory sockets, and the lobe itself is bounded below by the posterior cerebral commissure. The visceral lobe (cortex) extends along the corpus callosum to its base (cingulate gyrus) it is small in size, occupying a place between the cingulate gyrus and the corpus callosum. The pontine lobe passes from the corpus callosum with its bases and connects with the frontal lobe and temporal lobe. In essence, this area (pontine projection) is a soft medullary cone. Thus, the occipital lobe in an adult is characterized topographically by the frontal, temporal and cerebral regions. In this case, such a characteristic does not fully reflect the anatomical structure of the brain. The fetus has no restrictions, and accordingly the lobe has no division into layers. It is also necessary to say that animals do not have a cranial bone, so the concept of a lobe completely disappears. There are only anatomical components of the brain structure. From all this we can draw the following conclusion that the determination of the share of the head on each side cannot be considered definite and justified. As an auxiliary tool, it is possible to divide these lobes in order to study the function of a specific lobe according to zones and projections to brain zones.
