It is bounded caudally by the angular area 39 (H), rostrally and dorsally by the caudal postcentral area 2, and ventrally by the subcentral area 43 and the superior temporal area 22 (Brodmann-1909). Cytoarchitectonically defined subregions of rostral BA40/the supramarginal gyrus are PF, PFcm, PFm, PFop, and PFt. Area PF is the homologue to ...
Brodmann published his maps of cortical areas in humans, monkeys, and other species in 1909, [2] along with many other findings and observations regarding the general cell types and laminar organization of the mammalian cortex. The same Brodmann area number in different species does not necessarily indicate homologous areas. [3]
This area of the brain is also known as Brodmann area 40 based on the brain map created by Korbinian Brodmann to define the structures in the cerebral cortex. It is probably involved with language perception and processing, and lesions in it may cause receptive aphasia. [1]

Brodmann area 45 and 44 overlap with the Broca's area for language in humans; Brodmann area 1, 2, and 3 in the postcentral gyrus of the parietal lobe (the somatosensory region) Brodmann area 4 in the precentral gyrus of the frontal lobe (the primary motor area) Brodmann area 17 and 18 in the occipital lobe (the primary visual areas).
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 areas 41 and 42 are parts of the primary auditory cortex.. Brodmann area 41 is also known as the anterior transverse temporal area 41 (H). It is a cytoarchitectonic division of the cerebral cortex occupying the anterior transverse temporal gyrus (H) in the bank of the lateral sulcus on the dorsal surface of the temporal lobe.
Figure 3. Brodmann Brain Map: The SEF is located in the rostral supplementary motor area which corresponds to Area 6 in the above map. For reference, the FEF is located in Area 8. The eye field originally defined by Ferrier's map of the frontal cortex extended medially to the dorsal surface of the brain (Fig. 2). [9]
