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 ...
For example, Brodmann areas 1, 2 and 3 are the primary somatosensory cortex; area 4 is the primary motor cortex; area 17 is the primary visual cortex; and areas 41 and 42 correspond closely to primary auditory cortex.
[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]
Area 39 was regarded by Alexander Luria as a part of the parietal-temporal-occipital area, which includes Brodmann area 40, Brodmann area 19, and Brodmann area 37. Damage to the left Brodmann area 39 may result in dyslexia or in semantic aphasia. [1] Albert Einstein had less neurones (relative to glial cells) in this (left sided) area than ...
Brodmann area 37, or BA37, is part of the temporal cortex in the human brain.It contains the fusiform gyrus which in turn contains the fusiform face area, an area important for the recognition of faces.
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).
