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 auditosensory cortex is the part of the auditory system that is associated with the sense of hearing in humans. It occupies the bilateral primary auditory cortex in the temporal lobe of the mammalian brain. [1] The term is used to describe Brodmann areas 41 and 42 together with the transverse temporal gyrus. [2]
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. [1] It contributes to the dorsolateral and medial prefrontal cortex.
In children, early diagnosis and treatment of impaired auditory system function is an important factor in ensuring that key social, academic and speech/language developmental milestones are met. [43] Impairment of the auditory system can include any of the following: Auditory brainstem response and ABR audiometry test for newborn hearing
Coronal section of a human brain. BA41(red) and BA42(green) are auditory cortex. BA22(yellow) is Brodmann area 22, HF(blue) is hippocampal formation and pSTG is posterior part of superior temporal gyrus. The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates.
It is yet unclear whether auditory agnosia (also called general auditory agnosia) is a combination of milder disorders, such auditory verbal agnosia (pure word deafness), non-verbal auditory agnosia, amusia and word-meaning deafness, or a mild case of the more severe disorder, cerebral deafness. Typically, a person with auditory agnosia would ...
The transverse temporal gyrus, also called Heschl's gyrus (/ ˈ h ɛ ʃ əl z ˈ dʒ aɪ r aɪ /) or Heschl's convolutions, is a gyrus found in the area of each primary auditory cortex buried within the lateral sulcus of the human brain, occupying Brodmann areas 41 and 42.
The planum temporale is the cortical area just posterior to the auditory cortex (Heschl's gyrus) within the Sylvian fissure. [1] It is a triangular region which forms the heart of Wernicke's area , one of the most important functional areas for language. [ 2 ]
