The parietal lobes are divided into the superior and inferior parietal lobes. This region of the brain is known largely for visuo-spatial attention, navigation, the integration of senses and the major sensory inputs from the skin, which relay through the thalamus to the parietal lobes. The parietal lobe is abutted by the Rolandic Fissure, which runs coronally through the brain, the Sylvian Fissure, which separates the temporal lobe from the parietal and the frontal lobe, and the parieto-occipital sulcus.
<br><br>The posterior parietal cortex is made of the superior parietal lobe (Brodmann areas 5 and 7) and the inferior parietal lobes (Brodmann areas 39 and 40, which are separated by the intraparietal sulcus. This sulcus and the adjacent gyri are essential in limb and eye movement. Each hemisphere rules the sensation of the skin on the opposite side of the body. The parietal lobes are used for the manipulation of objects. The parietal lobe also includes the dorsal stream of vision, which is the “where” in space an object appears. And the “how” stream, which has to do with vision for action..
