Changes in BrainFunction and Function Brain Structure and Structure Nowadays, there is evidence that hearing impairment is associated Currently, there is evidence that hearing impairment is related with cerebral al- with cerebral alterations. Specifically, magnetic resonance imaging research demonstrate that hearing loss terations. Specifically, magnetic resonance imaging studies demonstrate that hearing loss is correlated with reduced complete brain and in the primary auditory cerebral is correlated with decreased volume on the volume from the whole brain and in the main auditory cerebral cortex in the [5,38] (Figure [5,38] (Figure 3). cortex within the temporal lobe temporal lobe 3).Figure resonance imaging, coronal view.

This with hearing impairment is lowered, especially inside the appropriate lateral Heschl’s gyrus, a vital region for auditory processing and that is also involved in a lot of other cognitive skills [44].
