Occipital lobe The occipital lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex.The primary visual cortex is Brodmann area 17, commonly called V1 (visual one).hus, the occipital lobe is defined as the part of the cerebral cortex that lies underneath the occipital bone. (See the human brain article for more information.). The lobes rest on the tentorium cerebelli, a process of dura mater that separates the cerebrum from the cerebellum.

Premotor cortex The premotor cortex is an area of motor cortex lying within the frontal lobe of the brain just anterior to the primary motor cortex. It occupies part of Brodmann's area 6. It has been studied mainly in primates, including monkeys and humans.

The Effects of an Occipital Lobe Stroke An occipital lobe stroke is a stroke that affects the back of the brain. The occipital lobe is the area of the brain that integrates our vision, allowing us to recognize and make sense of what our eyes see. In general, occipital lobe stroke are not common.

Occipital Lobe (Visual Cortex): Functional Aspects Much of this knowledge comes from studying the occipital lobe of the macaque, but the human occipital lobe appears generally closely similar. It maintains a basic spatial organization of visual information, but also extracts and organizes visual attributes such as local shape, motion, color, and depth.

visual cortex Called also first visual area. visual cortex the area of the occipital lobe of the cerebral cortex concerned with vision; the striate cortex is also called the first visual area, and the adjacent second and third visual areas serve as its association areas.rea 17 (which is also called the striate cortex or area because the line of Gennari is grossly visible on its surface) is the primary visual cortex, receiving the visual radiation from the lateral geniculate body of the thalamus.

The Four Cerebral Cortex Lobes of the Brain 1 Frontal Lobes: These lobes are positioned at the front-most region of the cerebral cortex. 2  Occipital Lobes: Located just below the parietal lobes, the occipital lobes are the main center for visual processing. 3  Temporal Lobes: These lobes are located directly below the frontal and parietal lobes.

Prefrontal cortex For the reptile scale, see Prefrontal scale. In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which covers the front part of the frontal lobe. The PFC contains Brodmann areas 9, 10, 11, 12, 46, and 47. third definition of the prefrontal cortex is the area of frontal cortex whose electrical stimulation does not lead to observable movements. For example, in 1890 David Ferrier used the term in this sense.

Occipital lobe The name derives from the overlying occipital bone, which is named from the Latin ob, behind, and caput, the head. Bilateral lesions of the occipital lobe can lead to cortical blindness (See Anton's syndrome).one of the cortical lobes are defined by any internal structural features, but rather by the bones of the head bone that overlie them. Thus, the occipital lobe is defined as the part of the cerebral cortex that lies underneath the occipital bone.

The Cerebrum The two occipital lobes are the smallest of the four paired lobes in the human cerebral cortex. Located in the rearmost portion of the skull, the occipital lobes are part of the forebrain. At the front edge of the occipital there are several lateral occipital gyri separated by lateral occipital sulci. The occipital lobe is involved in the sense of sight; lesions in this area can produce hallucinations.

- Gas pressure is defined as a the force of when it pushes out, and when its divided by the area of whatever it is in.ntensity of pressure is defined as the normal force per unit area on which the force acts. Intensity of pressure, p=f/a f=force exerted a=area on which force acts. 27 people found this useful.

Occipital Lobes and Visual Perception They are located in the largest division of the brain known as the forebrain (prosencephalon). Located within the occipital lobes is the primary visual cortex. This region of the brain receives visual input from the retina. These visual signals are interpreted in the occipital lobes.

- The correct answer is the first option - occipital lobe. The occipital lobe is a part of your brain which is governs your sight and all your visual activities. It got its name from Latin, because ob means behind, and caput means head, so this lobe is located in the back of your brain.

What Are the Functions of the Occipital Lobe? The occipital lobe, which is part of the human brain, is primarily responsible for processing and relaying visual cues. This lobe makes up one section of the larger cerebral cortex.
