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 transverse temporal gyrus, which contains the auditosensory cortex, processes sound impulse in low frequency. [13] Its lateral aspect maps the sound impulse in a tonotopic organisation that produces a mirror image of spatial gradients of frequency sensitivity. [14] It depends on the duration and intensity of the sound stimuli.
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 purpose of this frequency map (known as a tonotopic map) likely reflects the fact that the cochlea is arranged according to sound frequency. The auditory cortex is involved in tasks such as identifying and segregating "auditory objects" and identifying the location of a sound in space. For example, it has been shown that A1 encodes complex ...
BA 38 is at the anterior end of the temporal lobe, known as the temporal pole. BA38 is a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex . It is located primarily in the most rostral portions of the superior temporal gyrus and the middle temporal gyrus .
In the human superior temporal gyrus (STG), an anterior-posterior spatial organization of spectro-temporal modulation tuning has been found in response to speech sounds, the posterior STG being tuned for temporally fast varying speech sounds with low spectral modulations and the anterior STG being tuned for temporally slow varying speech sounds ...
In the human it is located on the medial surface of the temporal lobe. Cytoarchitectually it is bounded rostrally by the perirhinal area 35 and medially by the presubiculum. While described by Brodmann (Brodmann-1909), it was not included in his areal maps of human cortex (Brodmann-1909; Brodmann-1910).
In contrast to the ventral stream's auditory processing, information enters from the primary auditory cortex into the posterior superior temporal gyrus and posterior superior temporal sulcus. From there the information moves to the beginning of the dorsal pathway, which is located at the boundary of the temporal and parietal lobes near the ...
