Anatomical and Functional MRI Changes after One Year of Auditory Rehabilitation with Hearing Aids
Table 6
Regions of reduced cortical thickness in patients at baseline (PB) when compared to controls (CG). Mean cortical thickness is expressed in mm. The numbers in parentheses correspond to standard deviations. Statistical significance was set at .
