Unreferenced date August 2009 Orphan date November 2006 The parietal temporal occipital PTO association area is located in the cerebral cortex of the human brain . As its name implies, the PTO includes portions of the parietal lobe parietal , temporal lobe temporal and occipital lobe s. This association area one of three in the cortex is responsible for the assembly of sound auditory , visual perception visual , and somatosensory somatosensory system information. Meaning is assigned to stimuli in the PTO, which outputs to numerous other areas of the brain , notably the limbic system limbic and prefrontal cortex prefrontal association areas, which are involved in memory . In the left hemisphere, the PTO is involved in language recognition reading activity reading , listening, and braille , but is not entirely responsible for these tasks. Language in all its modalities is covered using many different parts of the brain including Heschl s gyrus in the left hemisphere.

Before an effective movement can be initiated, the nervous system must know the original positions of the body parts that are to be moved, and the positions of any external objects with which the body is going to interact. The posterior parietal cortex receives input from the three sensory systems that play roles in the localization of the body and external objects in space the visual system, the auditory system, and the somatosensory system. In turn, much of the output of the posterior parietal cortex goes to areas of frontal motor cortex the dorsolateral prefrontal cortex , various areas of the secondary motor cortex , and the frontal eye field . fMRI studies in monkeys and TMS studies in humans indicate that the posterior parietal cortex comprises a mosaic of small areas, each specialized for guiding particular movements of eyes, head, arms or hands. Damage to the posterior parietal cortex can produce a variety of sensorimotor deficits, including deficits in the perception and memory of spatial relationships, in accurate reaching and grasping, in the control of eye movement, and in attention.
