auditory cortex


Also found in: Dictionary, Thesaurus, Wikipedia.

au·di·to·ry cor·tex

the region of the cerebral cortex that receives the auditory radiation from the medial geniculate body, a thalamic cell group receiving auditory input from the cochlear nuclei in the rhombencephalon; it corresponds approximately to Brodmann areas 41 and 42 and is tonotopically organized.
Synonym(s): auditory area

The team focused on the primary auditory cortex, which is the first cortical region to receive auditory signals from the ears via other parts of the brain and the nonprimary auditory cortex, which plays a more sophisticated role in processing those stimuli.
Sensorineural hearing loss occurs from damage to the cochlea or disruption of the transmission of neural impulses from the cochlea to the auditory cortex.
There have been studies that showed a certain level of intramodal plasticity in the auditory cortex, particularly in the tonotopic area of the primary auditory cortex (A1).
We demonstrate that the auditory cortex is more adaptive to womblike maternal sounds than to environmental noise.
Similar to the somatosensory and visual cortices, the auditory cortex contains a topographical map corresponding to different acoustic frequencies at different cortical locations.
About half of the whole auditory cortex lit up in dogs when listening to these noises, compared with 3% of the same area in humans.
The primary auditory cortex is the region of the brain that is responsible for processing of auditory (sound) information.
He said: "It's a possible distress signal from the amygdala to the auditory cortex.
And now the team have revealed the interaction between the region of the brain that processes sound, the auditory cortex, and the amygdala, which is active in the processing of negative emotions when we hear unpleasant sounds.
The neural connections between the inner ear and primary auditory cortex of the brain are intact in virtually all cases of disabling hearing impairment.
Consequently, the primary auditory cortex on each side of the brain is sensitive to stimulation through either ear but is more strongly driven by contralateral stimulation.
