| Abstract: | Background Decrements of auditory evoked responses elicited by repeatedly presented sounds with similar frequencies have been well investigated
by means of electroencephalography and magnetoencephalography (MEG). However the possible inhibitory interactions between
different neuronal populations remains poorly understood. In the present study, we investigated the effect of proceeding notch-filtered
noises (NFNs) with different frequency spectra on a following test tone using MEG. |
