In a comparison among equipopulated groups for the signal power before normalization, the occipital electrode showed a significant ( p < .05) RMS increase in the “initial” set of measurements after deafening as compared to those “before” deafening, and a highly significant ( p < .001) increase in the “last” set of measurements after deafening as compared to those “before” deafening (Fig. 2 A).
