[[File:Parietal lobe animation small.gif|thumb|left|Animation. Parietal lobe (red) of left cerebral hemisphere.]]
The parietal lobe is defined by three anatomical boundaries: The central sulcus separates the parietal lobe from the frontal lobe; the [[parieto-occipital sulcus]] separates the parietal and [[occipital lobe]]s; the [[lateral sulcus]] (sylvian fissure) is the most lateral boundary, separating it from the temporal lobe; and the [[longitudinal fissure]] divides the two hemispheres. Within each hemisphere, the somatosensory cortex represents the skin area on the contralateral surface of the body.<ref name="Schacter, D. L. 2009"/>

Immediately posterior to the central sulcus, and the most anterior part of the parietal lobe, is the postcentral gyrus ([[Brodmann area]] 3), the primary [[somatosensory cortex|somatosensory cortical area]]. Separating this from the [[posterior parietal cortex]] is the [[postcentral sulcus]].

The posterior parietal cortex can be subdivided into the [[superior parietal lobule]] (Brodmann areas [[Brodmann area 5|5]] + [[Brodmann area 7|7]]) and the [[inferior parietal lobule]] ([[Brodmann area 39|39]] + [[Brodmann area 40|40]]), separated by the [[intraparietal sulcus]] (IPS). The intraparietal sulcus and adjacent [[gyrus|gyri]] are essential in guidance of limb and [[saccade|eye movement]], and—based on cytoarchitectural and functional differences—is further divided into medial (MIP), lateral (LIP), ventral (VIP), and anterior (AIP) areas.
