Group means (N = 15) of the N1 m source strengths for each experimental condition. The error-bars denote the 95% confidence interval limits of the arithmetic mean across subjects. The grey line marks the N1m responses elicited by the test stimulus during the constant sequencing, and the black line marks the N1m responses during the random sequencing.
