Overlapping perceptual benefits of temporal attention in aperiodic and periodic streams are mediated by delta phase alignment, but not alpha suppression, in sensory circuits
Predictions about the timing of upcoming stimuli allow to allocate attention proactively, facilitating perceptual processing. While both periodic and aperiodic predictions were associated with anticipatory suppression of occipital alpha-band activity, periodic predictions are thought to uniquely affect perception through entrainment of delta-band activity directly at the level of the sensory…
