Brodmann area 5 is a subdivision of the parietal cortex, part of the cortex in the human brain. BA5 is part of the superior parietal lobule and part of the postcentral gyrus . It is situated immediately posterior to the primary somatosensory cortex .
A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells. The concept was first introduced by the German anatomist Korbinian Brodmann in the early 20th century. Brodmann mapped the human brain based on the varied cellular ...
[5] Sir Grafton Elliot Smith (1871–1937), a New South Wales native working in Cairo, identified 50 areas. [6] Korbinian Brodmann worked on the brains of diverse mammalian species and developed a division of the cerebral cortex into 52 discrete areas (of which 44 in the human, and the remaining 8 in the non-human primate brain).

The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 , Brodmann area 17, or the striate cortex. The extrastriate areas consist of visual areas 2, 3, 4, and 5 (also known as V2, V3, V4, and V5, or Brodmann area 18 and all Brodmann area 19). [1]
Brodmann postulated that areas with different structures performed different functions. [5] Indeed, some of these areas were later associated to nervous functions, such as the following: Brodmann area 41 and 42 in the temporal lobe, related to hearing; Brodmann area 45 and 44 overlap with the Broca's area for language in humans
These subdivided cortical regions are later known as the Brodmann areas. Brodmann was the pioneer of cerebral cortex mapping. He grouped several cortical regions based on their nervous function, two of which are areas 41 and 42 for auditory processing. It has been suggested that Brodmann area 42 is a homotypical acoustic association area. [6]
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).
