Abstract
We observed significant MMN for the ITD/ILD traded deviants in case of the 500Â Hz pure tones, and for the 4000Â Hz amplitude-modulated tone. This speaks for independent processing of ITD and ILD at the level of the MMN within auditory cortex. However, the combined ITD/ILD cues elicited smaller MMN than the sum of the MMN induced in response to ITD and ILD cues presented in isolation for 500Â Hz, but not 4000Â Hz, suggesting independent processing for the higher frequency only. Thus, the two markers for independent processing - additivity and cue-conflict - resulted in contradicting conclusions with a dissociation between the lower (500Â Hz) and higher frequency (4000Â Hz) bands.
