[Effect of masking on interhemispheric and bilateral asymmetry of long-latency auditory evoked potentials]

Considering the effects of noise on the amplitude of long-latent auditory evoked potentials, it is concluded that masking interference diminishes the right hemisphere dominance in the processing of the non-speech acoustic information. The decrease is observed both with the monotic and dichotic delivery of signals and noise. With monotic presentation masking interference also decreases the extent of the lateralization of monaurally delivered information predominantly to the contralateral hemisphere.
