The auditory cortex takes part in the spectrotemporal, meaning involving time and frequency, analysis of the inputs passed on from the ear. The cortex then filters and passes on the information to the dual stream of speech processing. [5] The auditory cortex's function may help explain why particular brain damage leads to particular outcomes.
Cortical deafness is a rare form of sensorineural hearing loss caused by damage to the primary auditory cortex.Cortical deafness is an auditory disorder where the patient is unable to hear sounds but has no apparent damage to the structures of the ear (see auditory system).
Using cytoarchitectonics, BA 22 is located in the superior temporal gyrus which separates it from the primary and secondary auditory cortex. [2] BA 22 is connected with nonverbal sound processing in the right hemisphere of the brain associated with activation in the auditory cortex.
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 ...
Top: The auditory cortex of the monkey (left) and human (right) is schematically depicted on the supratemporal plane and observed from above (with the parieto- frontal operculi removed). Bottom: The brain of the monkey (left) and human (right) is schematically depicted and displayed from the side.
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
The basis for this discovery was the analysis of speech problems resulting from injuries to this brain region, located in the inferior frontal gyrus. Lesions to Broca's Area result primarily in disruptions to speech production. Damage to Wernicke's area, located in the lower part of the temporal lobe, mainly leads to speech reception disruptions.
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]
