Methods Alterations observed References MRI Reduced grey matter volume in bilateral  auditory areas
including the Heschl's gyrus.
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 .
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).
 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

Genuine laughter simply activates auditory areas
in the temporal lobe - where we process all sound.
Changes in auditory areas
of tinnitus sufferers comprise enhanced gamma activity [1-4], enhanced slow wave activity [1, 4-6], and reduced alpha activity .
Washington, Aug 31 (ANI): A new research has revealed that decline in hearing ability may accelerate gray matter atrophy in auditory areas
of the brain thereby increasing the listening effort necessary for older people to successfully comprehend speech.
Dr Frederic Joassin, Dr Salvatore Campanella, and colleagues compared the brain areas activated when recognising people using information from only their faces (visual areas), or only their voices (auditory areas
), to those activated when using the combined information.
Resting state studies mainly showed increased coherent activity of auditory areas
[12,13] with occasional reports of no changes between patients and controls .
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].
