Relationship to the auditory system. The auditory cortex is the most highly organized processing unit of sound in the brain. This cortex area is the neural crux of hearing, and—in humans—language and music. The auditory cortex is divided into three separate parts: the primary, secondary, and tertiary auditory cortex.
Auditosensory cortex. 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]
The inferior colliculi (IC) are located just below the visual processing centers known as the superior colliculi. The central nucleus of the IC is a nearly obligatory relay in the ascending auditory system, and most likely acts to integrate information (specifically regarding sound source localization from the superior olivary complex [ 16 ...
Graph showing a typical Auditory Brainstem Response. The auditory brainstem response (ABR), also called brainstem evoked response audiometry (BERA) or brainstem auditory evoked potentials (BAEPs) or brainstem auditory evoked responses (BAERs) [1] [2] is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp.
Audiology (from Latin audīre, "to hear"; and from Greek -λογία, -logia) is a branch of science that studies hearing, balance, and related disorders. [1] [2] Audiologists treat those with hearing loss and proactively prevent related damage. [3] By employing various testing strategies (e.g. behavioral hearing tests, otoacoustic emission ...
The roots of the term make its definition self-explanatory: audio for hearing, prosthetic for device, and ology for science. “Audio” as used in both “audiology” and “audioprosthology,” is derived from the Latin term “audire,” which means “to hear,” and is commonly used in numerous other English words that are related in varying ways to hearing and sound.
Auditory phonetics is the branch of phonetics concerned with the hearing of speech sounds and with speech perception.It thus entails the study of the relationships between speech stimuli and a listener's responses to such stimuli as mediated by mechanisms of the peripheral and central auditory systems, including certain areas of the brain.
Auditory neuropathy. Auditory neuropathy (AN) is a hearing disorder in which the outer hair cells of the cochlea are present and functional, but sound information is not transmitted sufficiently by the auditory nerve to the brain. The cause may be several dysfunctions of the inner hair cells of the cochlea or spiral ganglion neuron levels. [1]
