Top-down control of the phase of alpha-band oscillations as a mechanism for temporal prediction

摘要: The physiological state of the brain before an incoming stimulus has substantial consequences for subsequent behavior and neural processing. For example, phase ongoing posterior alpha-band oscillations (8–14 Hz) immediately visual stimulation been shown to predict perceptual outcomes downstream activity. Although this phenomenon suggests that these may phasically route information through functional networks, many accounts treat periodic effects as a consequence activity is independent behavioral strategy. Here, we investigated whether can be guided by top-down control in temporal cueing task. When participants were provided with cues predictive moment target onset, discrimination accuracy improved targets more frequently reported consciously seen, relative unpredictive cues. This effect was accompanied significant shift oscillations, toward each participant’s optimal discrimination. These findings provide direct evidence forming predictions about when will appear bias processing, thus serve mechanism processing predictions.
