Hwang et al report increased alpha/beta power in the frontal cortex during a fundamental test of cognitive control, the anti-saccade task. There was increased cross-frequency coupling between alpha and beta bands and alpha, specifically, was predictive of trial-by-trial success. This adds to the growing body of evidence that beta oscillations are associated with cognition and that alpha is important for inhibitory control.
