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 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 ...
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.
Temporal envelope (ENV) and temporal fine structure (TFS) are changes in the amplitude and frequency of sound perceived by humans over time. These temporal changes are responsible for several aspects of auditory perception, including loudness , pitch and timbre perception and spatial hearing .
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 ...
Area 37 – Fusiform gyrus; 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 ...
It is located primarily in the most rostral portions of the superior temporal gyrus and the middle temporal gyrus. Cytoarchitecturally it is bounded caudally by the inferior temporal area 20, the middle temporal area 21, the superior temporal area 22 and the ectorhinal area 36 (Brodmann-1909).
The superior temporal gyrus contains several important structures of the brain, including Brodmann areas 41 and 42, marking the location of the primary auditory cortex, the cortical region responsible for the sensation of basic characteristics of sound such as pitch and rhythm. We know from research in nonhuman primates that the primary ...
