Occipital Region of Interest (ROI) cortical visual evoked potentials (VEPs).

<p>A. Peak components P1, N1, and P2 amplitudes are significantly larger for the adult Hearing Loss (HL) group (red) in comparison to the adult Normal Hearing group (blue). Mean group differences are illustrated in corresponding mean bar graphs for each component. One asterisk indicates significance at <i>ρ</i> <0.05; two asterisks indicate significance at <i>ρ</i> <0.01. B. The N1 component latency is significantly decreased in the HL group as compared to the NH group, also illustrated in the mean bar graph. C. A third positive peak component, denoted as P2’, has been found in a subset of the HL group.
