    AbstractIn the present study we investigated the effects of anodal transcranial direct current stimulation over the auditory cortex (AC) on the perception of rapidly changing acoustic cues. For this purpose, in 15 native German speakers the left or right AC was separately stimulated while participants performed a between-channel gap detection task. Results show that stimulation of the left but not right AC deteriorated the auditory perception of rapidly changing acoustic information. Our data indicate a left hemispheric dominance for the processing of rapid temporal cues in auditory non-speech sounds. Moreover, we demonstrate the ability of non-invasive brain stimulation to change human temporal information processing in the auditory domain.Copyright © 2013 IBRO. Published by Elsevier Ltd.
