| More Details: | Latency and amplitude are the measurement parameters of mismatch negativity (MMN). The values of the parameters vary sensitively with the stimulus paradigm. A paradigm using the frequency difference of sounds for the MMN study is well known. This study obtained the reference values of the parameters in healthy young adults by performing the MMN study using the frequency paradigm. The authors recruited ten healthy adults. Their average age was 25.5 years; three were female, and seven were male. On the auditory paradigm for the MMN study, the frequency of sound was 1000 Hz for the standard stimulus, and 1032 Hz for the deviant stimulus. The mean values of latency and amplitude of MMN were 202 ms and 1.88 μV at Fz, 207 ms, and 1.46 μV at Cz, 212 ms, and 1.10 μV at C3, and 214 ms and 1.45 μV at C4. There was no correlation between the latency and amplitude of MMN. This study presented the reference values of the latency and amplitude of the MMN using a standard paradigm that is easy to apply. This information may make the MMN useful for clinical applications and basic research. |
