Phase values of the alpha band. The phase-locked values of the alpha band for phase-locked and nonphase-locked activities following the presentation of the target (20 subjects). The green dots and red crosses represent phase-locked and nonphase-locked activity (respectively) when the target is displayed in the left visual field. Yellow dots and blue crosses are when the target was displayed in the right visual field. The individual representations demonstrate that nonphase-locked values are randomly distributed in all subjects and are not centered around the values of phase-locked activity.
