Parietal lobe

www.memorylossonline.com_glossary_images_parietallobe.jpg The parietal lobe is one of the four major lobes of the cerebral cortex in the brain.

The parietal lobe is positioned above (superior to) the occipital lobe and behind (posterior to) the frontal lobe and central sulcus.


The parietal lobes can be divided into two functional regions. One involves sensation and perception and the other is concerned with integrating sensory input, primarily with the visual system. The first function integrates sensory information to form a single perception (cognition). The second function constructs a spatial coordinate system to represent the world around us. Individuals with damage to the parietal lobes often show striking deficits, such as abnormalities in body image and spatial relations 1).

Parietal areas play a crucial role in calculation processing

The parietal lobe processes sensory information and is involved in orientation and recognition.

The parietal lobe contains areas responsible for the sensation of touch and association, this area enables fine judgement of sensation such as texture, weight, size.

In 28 consecutive patients who underwent resection of a glial neoplasm found on imaging studies to be confined to the parietal lobe. Neurological deficits were correlated with hemispheric dominance, location of the lesion within the superior or inferior parietal lobules, subcortical extension, and involvement of the postcentral gyrus 2).
