The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain's primary sensory area, a region where the brain interprets input from other areas of the body.
What is parietal used for?
What is parietal used for? The parietal lobe plays important roles in integrating sensory information from various parts of the body, knowledge of numbers and their relations, and in the manipulation of objects. Its function also includes processing information relating to the sense of touch. Click to see full answer.
What happens when the parietal lobe is damaged?
Thus, if the parietal lobe is damaged, those nerve signals can’t travel as easily. Parietal lobe damage makes it more difficult to process certain visual information such as length and depth. This leads to poor hand-eye coordination and balance, as well as several other eye problems.
What is the function of the parietal cortex?
The parietal lobes are one of the four main lobes or regions of the cerebral cortex. The parietal lobes are positioned behind the frontal lobes and above the temporal lobes. These lobes are important to the function and processing of sensory information, understanding spatial orientation and body awareness.

What is the Function of the Parietal Lobe?
The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain's primary sensory area, a region where the brain interprets input from other areas of the body. Research suggests that, the more sensory input a region of the body provides, the more surface area of the parietal lobe is dedicated to that area. For example, the fingers and hands are a primary site for sensory data, so much of the parietal lobe is dedicated to receiving and processing their input.
What is the role of the parietal lobe in sensory processing?
Its role in sensory processing means that the parietal lobe depends on a cascade of sensory input from all over the body, including the eyes, hands, tongue, and skin. These disparate regions cannot function without the input of the parietal lobe, which assigns meaning to the sensory input you encounter each day.
Where is the Parietal Lobe Located?
The brain is divided into a number of regions, but the area most humans refer to when they discuss the brain is the cerebral cortex, or cerebrum. This evolutionarily new region of the brain is present in all mammals, and is what allows complex thoughts rather than just automatic and unconscious processes.
How Does the Parietal Lobe Interact With Other Areas of the Body?
Without the environment, the brain could do little or nothing, and the parietal lobe is no exception. Its role in sensory processing means that the parietal lobe depends on a cascade of sensory input from all over the body , including the eyes, hands, tongue, and skin. These disparate regions cannot function without the input of the parietal lobe, which assigns meaning to the sensory input you encounter each day.
How Does Damage to the Parietal Lobe Affect Functioning?
The specific prognosis depends in large part on the location of the injury, the severity of the injury, and whether the injury can be treated. For instance, a lesion pressing on the parietal lobe will have a better prognosis with improved functioning if the lesion can be removed.

What is the function of the superior parietal lobule?
The superior parietal lobule forms the association cortex of the parietal lobe, and plays an important role in planned movements, spatial reasoning and attention. The intraparietal sulcus can be further divided into a lateral, medial, ventral and anterior area. The lateral area is responsible for our eye movements in response to a stimulus in space. The medial area helps us to determine how far and where we need to reach in relation to our nose. The ventral area is an area that receives a number of sensory modalities; these include auditory, visual, vestibular and somatosensory information. Finally, the anterior area enables us to interpret the size, shape and position of objects we are about to grasp. The anterior and ventral areas work together to enable visual motor coordination of hand movements.
What is the parietal lobe?
The parietal lobe occupies about one quarter of each hemisphere and is involved in two primary functions: 1) sensation and perception and 2) the integration and interpretation of sensory information, primarily with the visual field.
Where does the inferior parietal lobule originate?
The inferior parietal lobule continues to the parieto-temporal intersection, and is formed by the supramarginal gyrus and the angular gyrus.
Which sulcus is parallel to the cingulate?
Running almost parallel with the central sulcus is the post-central sulcus. Both sulci demarcate the post-central gyrus, located about 6.5 cm posterior to the bregma of the skull. Because the marginal sulcus (or ascending band of the cingulate) points directly to the post-central gyrus on the superior surface of the hemisphere, it serves as an important landmark for identifying the gyrus (particularly on MRIs).
Where is the parietal lobe located?
The parietal lobe is located between the frontal and occipital lobe and above the temporal lobe on each cerebral hemisphere. Its borders are as follows: Posterior border - formed by the imaginary line extending between the parieto-occipital sulcus (superiorly) and the preoccipital notch (inferiorly).
Which lobe is the posterior part of the paracentral lobule?
On the medial surface of the hemisphere, the parietal lobe forms the posterior part of the paracentral lobule, which is demarcated by the pre-central sulcus anteriorly and the marginal sulcus posteriorly. Just posterior to the paracentral lobule is the precuneus lobule, which extends from the supramarginal sulcus to the parieto-occipital sulcus.
What is the role of the parietal lobe in the human body?
