Query: Cross-modal alterations of Alpha Activity do not reflect inhibition of early sensory processing: A frequency tagging study Selective attention refers to the prioritization of relevant and suppression of irrelevant sensory input. Oscillatory alpha-band activity ([~]10 Hz) has been suggested to facilitate this process by functional inhibition of early sensory regions. The objective of the current EEG study was to compare this theory to a  gating function at later stages of the processing stream. Visual cues indicated whether an upcoming target required visual orientation or more demanding auditory pitch discrimination. To gauge inhibition, we probed the visual and auditory systems with frequency-tagging during the cue-to-target interval, flickering the fixation cross at 36 Hz and simultaneously playing amplitude-modulated white noise at 40 Hz. In line with previous work, we observed a post-cue increase in posterior alpha activity when anticipating auditory targets. Surprisingly, the amplitude of visual and auditory responses increased in anticipation of auditory targets, correlated with alpha activity. This indicates that responsiveness of the visual stream was not inhibited when attention was directed to auditory processing. Furthermore, anticipation of demanding auditory targets heightened the vigilance of the sensory system, independent of sensory modality. Our findings suggest that alpha modulation does not reflect  gain control in early sensory areas, but rather exhibits its inhibitory effects at later stages.
