Definition
The parietal lobe is part of the forebrain and lies between the frontal lobe abnd occipital lobe. It plays an important role in integrating information from different sensory modalities (vision, touch, hearing). It is particularly involved in the perception of space and attention and, more specifically, the superior parietal cortex is involved in the visuomotor control of movements, including saccades eye movements.
Structure The parietal lobe occupies the middle and superior part of the hemisphere, being limited posteriorly by the parieto-occipital sulcus, anteriorly by the central fissure and below by the Sylvian fissure. It contains a fissure (the intraparietal sulcus) that further splits it into postcentral and horizontal sulci that separate 3 convolutions (posterior central, supramarginal and angular gyri).
Function The parietal lobes contain the postcentral gyrus, which is essentially a topical representation of the somatic sensory innvervation to various contralateral parts of the body with the more sensitive areas receiving more representation (sensory homunculus).
Caudal to this area, the parietal lobe is divided into a superior and inferior lobe. The inferior portion is responsible integration of information for speech. The superior portion is important for the recognition of the surrounding environment, including oneself.
The parietal lobes of the cerebral cortex are able to organize information from the senses regarding the shape, texture and weight and transform them into general perceptions. Mathematical skills and language have their origin somewhere in that area, more specifically in the areas adjacent to the temporal lobes. The parietal lobes also help people to orient themselves in space and realize the position of body parts.
Disease A deficit in the anterior part of the parietal lobes produces numbness on the opposite side of the body. Individuals with larger lesions may develop apraxia and awareness of the right-left directions. The ability to recognize parts of the body or the space can become impaired, sometimes causing the individual to ignore the seriousness of their problem and neglect or even deny the existence of paralysis affecting one side of the body opposite the brain lesion. Gerstmann?s syndrome, Balint?s syndrome, and hemispheral neglect are all associated with parietal lobe dysfunction.
Treatment would involve therapy in less extreme cases, and permanent care assistance for those with extreme damage.
