 Abstract: The amplitude of [alpha] waves in an ongoing electroencephalogram can be reduced by visual stimuli and by attention. We reduced [alpha] amplitudes by presenting a short visual stimulus in the visual periphery, 10[degrees] apart from the fovea, and measured (i) the decrease of [alpha] amplitudes as a function of time and (ii) delays in reaction to foveal stimuli presented at various intervals after the peripheral stimulus. It turned out that in the time window from 0 to 2 s after the peripheral stimulus, both responses decrease in parallel with a minimum at 350-500 ms. The close correspondence between [alpha] amplitude and reaction time supports the view that [alpha] waves are functionally relevant for this behaviour.
