Top-down Control of Visual Alpha Oscillations: Sources of Control Signals and Their Mechanisms of Action
Alpha oscillations (8 to 12 Hz) are thought to inversely correlate with cortical excitability. Goal-oriented modulation of alpha has been studied extensively. In visual spatial attention, alpha over the region of visual cortex corresponding to the attended location decreases, signifying increased ex...
