Resumo: | ABSTRACT Purpose: this study aimed at illustrating the similarities and differences in the recording of components P1 and N1 for verbal and non-verbal stimuli, in an adult sample population, for reference purposes. Methods: twenty-one adult, eutrophic individuals of both sexes were recruited for this study. The long-latency auditory evoked potential was detected by bilateral stimulation in both ears, using simultaneous recording, with non-verbal stimuli and the syllable /da/. Results: for non-verbal and speech stimuli, N1 was identified in 100.0% of the participants, whereas P1 was observed in 85.7% and 95.2% individuals for non-verbal and speech stimuli, respectively. Significant differences were observed for the P1 and N1 amplitudes between the ears (p <0.05); the P1 component, in the left ear, was higher than that in the right ear, whereas the N1 component was higher in the right one. Regarding the stimuli, the amplitude and latency values of N1 were higher for speech, whereas in P1, different results were obtained only in latency. Conclusion: the N1 component was the most frequently detected one. Differences in latency and amplitude for each stimuli occurred only for N1, which can be justified by its role in the process of speech discrimination. |
