Abstract

If visual stimulation is made contingent on a unilateral occipital EEG, there is an increase in the control of the alternation between alpha and little or no alpha on the side used to control the visual stimuli as compared to the other side. Previous studies using a visual stimulus for feedback, did not control for the possibility that “feedback” effects might be produced by non‐contingent intermittent stimulation. This experiment was a yoked‐cortex control for intermittent non‐contingent vs intermittent contingent stimulation. The result show that the effects observed are due to contingent stimulation and not merely due to intermittent stimulation.
