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.
[5] [6] Some identify it with the unimodal auditory association in the superior temporal gyrus anterior to the primary auditory cortex (the anterior part of BA 22). [7] This is the site most consistently implicated in auditory word recognition by functional brain imaging experiments.
In the last two decades, significant advances occurred in our understanding of the neural processing of sounds in primates. Initially by recording of neural activity in the auditory cortices of monkeys [18] [19] and later elaborated via histological staining [20] [21] [22] and fMRI scanning studies, [23] 3 auditory fields were identified in the primary auditory cortex, and 9 associative ...
Ears are picking up auditory stimuli that are sent to the brain’s auditory cortex, and eyes are absorbing photic energy from the screen and sending a rapid sequence of stimuli to the visual cortex.
The auditosensory cortex takes part in the reception and processing of auditory nerve impulses, which passes sound information from the thalamus to the brain. Abnormalities in this region are responsible for many disorders in auditory abilities, such as congenital deafness , true cortical deafness, primary progressive aphasia and auditory ...
The superior temporal gyrus contains several important structures of the brain, including: Brodmann areas 41 and 42, marking the location of the auditory cortex, the cortical region responsible for the sensation of sound; Wernicke's area, Brodmann area 22, an important region for the processing of speech so that it can be understood as language.
Language processing is a function more of the left side of the brain than the right side, particularly Broca's area and Wernicke's area, though the roles played by the two sides of the brain in processing different aspects of language are still unclear. Music is also processed by both the left and the right sides of the brain.
Lateralization of brain function exists in the cortex, with the processing of speech in the left cerebral hemisphere and environmental sounds in the right hemisphere of the auditory cortex. Music, with its influence on emotions, is also processed in the right hemisphere of the auditory cortex.
