The simultaneous recording of auditory evoked potentials with logarithmic time scale were tried in order to simplify display of the successive components of the potentials in infants. The subjects were 16 normal infants aged from 2 months to 5 years old. The results were as follows;
1) The logarithmic scale display of the auditory potentials in infants revealed the same modality with those of adults. (Audiology Japan, 26, 735-739, 1983) Each component of potentials mainly generated from the 8th nerve up to the auditory cortex could be identified clearly without missing its charactristics.
2) The discrepancy of the pattern of the potentials between adults and infants was the presence of a deep negative potential following the wave 2 of ABR in infants, especially under the age of 12 months.
3) The logarithmic time scale display showed the possibility of the duplication between slow positive ABR and Po of MLR, and nextly Pa, Pb of MLR and P1 of SVR, and furthermore, Nc of MLR and N1 of SVR. These modalities of duplications were the same with those of adults.
