The parietal-temporal-occipital (PTO) association area, also referred to as the temporo-parieto-occipital (TPO) junction, is an area within the cerebral cortex where the parietal, temporal and occipital lobes meet. [1] High level of interpreting meaningful signals in the surrounding sensory area. They have functional subareas:
The brain contains four main lobes: temporal lobe, parietal lobe, frontal lobe, and the occipital lobe. The temporoparietal junction lies in the region between the temporal and parietal lobes, near the lateral sulcus (Sylvian fissure). Specifically, it is composed of the inferior parietal lobule and the caudal parts of the superior temporal ...
[1] This area is among the earliest affected by Alzheimer's disease, frontotemporal dementia, frontotemporal lobar degeneration, and is commonly involved at the start of temporal lobe seizures. [3] Cytoarchitectonic and chemoarchitectonic studies find that it contains at least seven subareas, one of which, "TG", is unique to humans. [3]

[3] [4] [5] Brodmann area 7 is part of the superior parietal lobule, [3] [6] but some sources include Brodmann area 5. [6] The inferior parietal lobule is further subdivided into the supramarginal gyrus, the temporoparietal junction, and the angular gyrus. [3] [4] [5] The inferior parietal lobule corresponds to Brodmann areas 39 and 40. [3] [5]
The superior parietal lobule contains Brodmann's areas 5 and 7. Behind it is the lateral part of the parieto-occipital sulcus, around the end of which it is joined to the occipital lobe by a curved gyrus, the arcus parietooccipitalis. Below, it is separated from the inferior parietal lobule by the horizontal portion of the intraparietal sulcus.
The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 cm in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parieto-occipital sulcus (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure ...
Brodmann area 7 is part of the parietal cortex in the human brain. Situated posterior to the primary somatosensory cortex ( Brodmann areas 3, 1 and 2 ), and superior to the occipital lobe , this region is believed to play a role in visuo-motor coordination (e.g., in reaching to grasp an object).
