Abstract
In all experimental conditions, LAEP amplitudes are linearly related to the dB scaled power ratio of correlated (N0) versus anticorrelated (NÏ) signal components. The voltage gain of LAEP per dB(N0/NÏ) closely corresponds to a constant perceptual distance between two correlations. We therefore suggest that activity in the auditory cortex and perceptual IAC sensitivity are better represented by the dB-scaled N0/NÏ power ratio than by the normalized IAC itself.
