The analysis revealed a relationship between pre-stimulus alpha power and the P1 component in controls, whereby greater pre-stimulus alpha led to greater P1 amplitudes for the 8% (F(1,418) = 14.86, p = 0.0001 ; R 2 = .06), and 57% (F(1,418) = 28.54, p = 1.51 × 10 −7 ; R 2 = .09) contrast conditions and a trend towards significance for the 2% contrast condition (F(1,418) = 3.67, p = 0.056; R 2 = .01).
