Brodmann area 22 is a Brodmann's area that is cytoarchitecturally located in the posterior superior temporal gyrus of the brain. [1] In the left cerebral hemisphere, it is one portion of Wernicke's area. [1] The left hemisphere BA22 helps with generation and understanding of individual words.
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 ...
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]
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]
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 ...
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).
The damaged area was named Wernicke's area, and is located in the left hemisphere’s posterior superior temporal gyrus (Brodmann area 22). Signers with damage in Broca's area have problems producing signs. Those with damage in the Wernicke's area (left hemisphere) in the temporal lobe of the brain have problems comprehending signed languages ...
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.
