auditory area


Also found in: Dictionary, Thesaurus.

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

In deaf humans, it was found that auditory areas preserved the task-specific activation pattern independent of input modality (visual or auditory), suggesting the task-specific reorganization during the cortical plasticity [55].
In oral language, auditory input is transmitted from the medial geniculate nucleus in the thalamus to both primary auditory areas (PA) and auditory association areas (AA), the latter of which may contain phonologic representations of words (Binder et al., 1994).
[7] Spectral and temporal discrimination are known as central auditory skills, and therefore, it has been hypothesized that better auditory-perceptual skills in the blind are due to faster or more efficient processing in cortical auditory areas. [8]

Resting state studies mainly showed increased coherent activity of auditory areas [12,13] with occasional reports of no changes between patients and controls [14].
And they have now shown that neurons tuned to the fundamental frequencies and harmonic sounds, and such neural mechanisms of harmonic processing lay close to tonotopically organized auditory areas.
Cats that were deprived of vision from birth also show expanded primary somatosensory and auditory areas; furthermore, the neurons in the anterior ectosylvian visual area (AEV) that normally respond to visual stimuli are replaced by neurons of neighboring auditory ectosylvian area (AEA), which is accompanied by the improvement of auditory spatial tuning of this region than sighted controls [118, 119].
