The major sensory inputs from the skin (touch, temperature, and pain receptors), relay through the thalamus to the parietal lobe.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.[9] The posterior parietal cortex (PPC) receives somatosensory and visual input, which then, through motor signals, controls movement of the arm, hand, and eyes.Damage to this lobe in the left hemisphere will result in problems in mathematics, long reading, writing, and understanding symbols.Optic ataxia is associated with difficulties reaching toward objects in the visual field opposite to the side of the parietal damage.[27] Can also result in sensory impairment where one of the affected person's senses (sight, hearing, smell, touch, taste and spatial awareness) is no longer normal.
