Event-related potential (ERP) difference waveforms and scalp topography maps comparing cochlear implant (CI) users and normal hearing (NH) individuals during an auditory oddball paradigm. (a) FCz electrode recordings showing NH participants (red lines) exhibiting substantially larger amplitude responses than CI users (blue lines) (*** p < 0.001), for novel stimuli (~ 12 µV vs. ~5 µV peak). Scalp maps below reveal more pronounced frontocentral activation patterns in NH individuals. (b) PZ electrode recordings demonstrating a different pattern where target responses (dashed lines) become more prominent than novel responses (solid lines), with scalp distributions indicating stronger parietal activation. Green boxes highlight the time windows of interest (350–650 ms) corresponding to the P3 component.
