What does the parietal lobe lobe do?

What does the parietal lobe lobe do?

The parietal lobes are located near the back and top of the head. They are important for processing and interpreting somatosensory input. Eg. they inform us about objects in our external environment through touch (i.e., physical contact with skin) and about the position and movement of our body parts (proprioception).

What structures are in the parietal lobe?

The parietal lobe, posterior to the central sulcus, is divided into three parts: (1) the postcentral gyrus, (2) the superior parietal lobule, and (3) the inferior parietal lobule. The postcentral gyrus receives sensory input from the contralateral half of the body.

What other structures are near the parietal lobe?

The parietal lobe also sits above the temporal lobe, with the Sylvian fissure, or lateral sulcus, separating the two. The occipital lobe is behind and slightly underneath the parietal lobe. The parieto-occipital sulcus divides these two lobes.

What does the parietal lobe do without the environment?

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.

What separates the occipital and parietal lobes?

A boundary called the central sulcus separates the two lobes. The parietal lobe also sits above the temporal lobe, with the Sylvian fissure, or lateral sulcus, separating the two. The occipital lobe is behind and slightly underneath the parietal lobe.

What happens when the parietal lobe is damaged?

Damage to the front portion of the parietal lobe may make it difficult for a person to recognize objects based on their sense of touch. Agraphesthesia is another possible outcome of damage to the parietal lobe. A person with this condition cannot detect or identify basic shapes or letters drawn onto their skin.

What is the function of the superior parietal lobule?

It also plays a role in attention, particularly attention driven by new stimuli, such as when an animal jumps into the road while you are driving. Superior parietal lobule: This region helps you determine your own orientation in space, as well as the orientation of other objects.
