Wernicke's area (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is primarily involved in the ...
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]
Brodmann areas 41 and 42, marking the location of the auditory cortex, the cortical region responsible for the sensation of sound; Wernicke's area, Brodmann area 22, an important region for the processing of speech so that it can be understood as language.
Brodmann areas 3, 1, and 2 make up the primary somatosensory cortex of the human brain (or S1). [2] Because Brodmann sliced the brain somewhat obliquely, he encountered area 1 first; however, from anterior to posterior , the Brodmann designations are 3, 1, and 2, respectively.
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.
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]
In neuroanatomy, the arcuate fasciculus (AF; from Latin 'curved bundle') is a bundle of axons that generally connects Broca's area and Wernicke's area in the brain. It is an association fiber tract connecting caudal temporal lobe and inferior frontal lobe. [1]
Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production.
