The parietal lobe integrates sensory information from different modalities, particularly determining spatial sense and navigation. For example, it comprises somatosensory cortex and the dorsal stream of the visual system. This enables regions of the parietal cortex to map objects perceived visually into body coordinate positions. Senses are the physiological methods of perception. ...

Anatomy
The parietal lobe is defined by four anatomical boundaries: the central sulcus separates the parietal lobe from the frontal lobe; the parieto-occipital sulcus separates the parietal and occipital lobes; the lateral sulcus (sylvian fissure) is the most lateral boundary separating it from the temporal lobe; and the medial longitudinal fissure divides the two hemispheres. Central sulcus of the human brain. ...

The posterior parietal cortex can be subdivided into the superior parietal lobule (Brodmann areas 5 + 7) and the inferior parietal lobule (39 + 40), separated by the intraparietal sulcus (IP). The intraparietal sulcus and adjacent gyri are essential in guidance of limb and eye movement, and based on cytoarchitectural and functional differences is further divided into medial (MIP), lateral (LIP), ventral (VIP), and anterior (AIP) areas. The superior parietal lobule is bounded in front by the upper part of the postcentral sulcus, but is usually connected with the posterior central gyrus above the end of the sulcus; behind it is the lateral part of the parietoöccipital fissure, around the end of which it is joined...

Function The parietal lobe plays important roles in integrating sensory information from various parts of the body, knowledge of numbers and their relations[1], and in the manipulation of objects. Portions of the parietal lobe are involved with visuospatial processing. Much less is known about this lobe than the other three in the cerebrum.
Various studies in the 1990s found that different regions of the parietal cortex in Macaques represent different parts of space. For other uses, see Macaca. ...
- The lateral intraparietal (LIP) contains a 2-dimensional topographic map of retinotopically-coded space representing the saliency of spatial locations. It can be used by the oculomotor system for targeting eye movements, when appropriate.
- The ventral intraparietal (VIP) area receives input from a number of senses (visual, somatosensory, auditory, and vestibular[2]). Neurons with tactile receptive fields represented space in a head-centered reference frame[2]. The cells with visual receptive fields also fire with head-centered reference frames[3] but possibly also with eye-centered coordinates[2]
- The medial intraparietal (MIP) area neurons encode the location of a reach target in eye-centered coordinates.[4]
- The anterior intraparietal (AIP) area contains neurons responsive to shape, size, and orientation of objects to be grasped[5] as well as for manipulation of hands themselves, both to viewed[5] and remembered stimuli. [6]
The somatosensory system is the sensory system of somatic sensation. ...
The vestibular system, or balance system, is the sensory system that provides the dominant input about movement and equilibrioception. ...
Tactition is the sense of pressure perception. ...
Pathology Gerstmann's syndrome is associated with lesion to the dominant (usually left) parietal lobe. Balint's syndrome is associated with bilateral lesions. The syndrome of hemispatial neglect is usually associated with large deficits of attention of the non-dominant hemisphere. Gerstmanns syndrome is a neurological disorder characterized by four primary symptoms: Agraphia/dysgraphia Acalculia/dyscalculia Finger agnosia Left-right disorientation In adults, the syndrome may occur after a stroke or in association with damage to the parietal lobe. ...
Balints syndrome, identified by Rezsö (Rudolf) Bálint in 1909, is the inability to perceive the visual field as a whole, resulting in the unpredictable perception and recognition of only parts of it (simultagnosia). ...
It has been suggested that this article or section be merged with Unilateral neglect. ...
