Area 38 – Temporopolar area (most rostral part of the superior and middle temporal gyri) Area 39 – Angular gyrus, considered by some to be part of Wernicke's area; Area 40 – Supramarginal gyrus considered by some to be part of Wernicke's area; Areas 41 and 42 – Auditory cortex; Area 43 – Primary gustatory cortex
The impulse propagates across the auditosensory area, the auditopsychic area and eventually the entire temporal lobe. Therefore, this allows the formation of memory and comprehension of sound to take place. The posterior auditopsychic region has a site especially for an understanding of speech called the Wernicke's area (Brodmann area 22).
Wernicke's area is active in processing language and consists of the left Brodmann area 22 and Brodmann area 40, the supramarginal gyrus. It is bounded rostrally by Brodmann area 38, medially by Brodmann area 42, ventrocaudally by Brodmann area 21, and dorsocaudally by Brodmann area 40, and Brodmann area 39.
The superior temporal gyrus also includes Wernicke's area, which (in most people) is located in the left hemisphere. It is the major area involved in the comprehension of language. The superior temporal gyrus is involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition. [2] [3]
It is traditionally thought to reside in Brodmann area 22, located in the superior temporal gyrus in the dominant cerebral hemisphere, which is the left hemisphere in about 95% of right-handed individuals and 70% of left-handed individuals. [1] Damage caused to Wernicke's area results in receptive, fluent aphasia. This means that the person ...
The supramarginal gyrus is a portion of the parietal lobe.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.
The retrosplenial cortex (RSC) is a cortical area in the brain comprising Brodmann areas 29 and 30. [1] It is secondary association cortex, making connections with numerous other brain regions. The region's name refers to its anatomical location immediately behind the splenium of the corpus callosum in primates, although in rodents it is ...
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).
