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

Brain scans showed that the human auditory cortex was much more responsive than the monkey cortex when they compared relative activity between the calls and toneless, noisy versions of the calls.

These findings again suggest a delay in the conduction of auditory impulses from the level of the medial geniculate body to the auditory cortex. This indicates that the auditory pathway is affected greatly with increased duration of mobile phone usage.
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.
Thus, these results suggest that a high activation of the auditory cortex suppresses visually evoked V1 activity.

"Not only do humans prefer to hear in the right ear, we actually hear information better in our right ears." In order to report from the left ear, the signal has to travel from the right auditory cortex, via the corpus callosum, to the language dominant left temporal region.
Primary auditory cortex lies in Heschl gyri, on posterosuperior aspect of temporal lobe deep within the Sylvian fissure, that is, areas 41 and 42.

Finally, the articles that described the use of non-vocal stimuli addressed the sensitivity and activation of the auditory cortex for acoustic stimuli with different temporal structures [21,23], and the relation of hemodynamic responses among the cortical regions [24].
Which means a unique brain wave or an electrical activity in the Auditory Cortex has suddenly stopped for 10 minutes and then this same activity with the same unique brain wave has started again by giving this person the perception of the sound of same Tinnitus.
In the best lip-readers, activity in the auditory cortex was quite similar to that evoked when the story was read aloud, brain scans revealed.
