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 ...
For example, Brodmann areas 1, 2 and 3 are the primary somatosensory cortex; area 4 is the primary motor cortex; area 17 is the primary visual cortex; and areas 41 and 42 correspond closely to primary auditory cortex.
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]
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.
The distinct structure occupied Brodmann area 42 and was later named the transverse temporal gyri of Heschl. [4] The discovery provided insight into the anatomical network within the primary cortex. It is the first site to process incoming sound information. Due to the close correspondence, Brodmann area 42 is also referred to as Heschl's gyrus ...
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.
Myelination is a process by which axons are covered with a protective substance called myelin that drastically increases the signaling efficiency of the neuron. [7] The arcuate fasciculus is heavily myelinated in healthy adult brains.
It represents the Brodmann area 39. [1] Its significance is in transferring visual information to Wernicke's area, in order to make meaning out of visually perceived words. [2] It is also involved in a number of processes related to language, number processing and spatial cognition, memory retrieval, attention, and theory of mind.
