ABSTRACT
OBJECTIVE@#To investigate the relationships of electrophysiological characteristics between speech evoked auditory brainstem response (s-ABR) and auditory mismatch negativity (MMN), so as to provide more clues for the mechanism of speech cognitive behavior.@*METHOD@#Thirty-three ears in 33 normal hearing adults were included in this study. Their s-ABR were recorded with speech syllables /da/ at 80 dB HL intensity. Meanwhile, two MMNs were recorded with 1 kHz frequency deviant extent and 40 dB intensity deviant extent in them. The electrophysiological characteristics of s-ABRs and MMNs, as well as the relationships of MMN latencies between s-ABR parameters including latencies in time domain, fundamental frequency(F0) and first formants(F1) in frequency domain were analyzed statistically.@*RESULT@#MMN latency of frequency deviance showed a negative correlation tendency with s-ABR transient components, and it showed a positive trend with sustained components of s-ABR. While MMN latency of intensity deviance showed a positive correlation with s-ABR latency of peak V, A and D respectively, and it negatively showed a correlation with s-ABR latency of other peak s and amplitude of F0 and FI respectively. Only the s-ABR latency of peak F and MMN latency of frequency deviance, and the F0 amplitude of s-ABR and MMN latency of intensity deviance were moderate correlation statistically.@*CONCLUSION@#It was probably the neurons of frequency deviant MMN unmatched the characteristics of frequency with the neurons of s-ABR transient component, but well matched the characteristics of frequency with the neurons of s-ABR sustained component. Similarly, the neurons of intensity deviant MMN probably matched the characteristics of intensity with neurons of different components of s-ABR or not. These results may formed as a valuable clue for further investigation of speech perception and temporal processing abilities.
