Figure 3. ERP aligned to the onset of noise bursts:

a,b,c, 50-ms noise burst presented together with the tone; d,e,f 50-ms noise burst alone. g,h,i 1000-ms noises together with the tone (see also insets in panels a,d,g). A,d,g: Lines are group means and shaded areas are standard errors. Horizontal gray lines denote time windows of interest. Gray asterisks next to them indicate the significant correlation between magnitude and performance (test was done using all 35 participants, and not only the two groups of participants depicted here for clarity). Panels b,e,h refer to P50 component (40–66 ms after sound onset). Panels c,f,i refer to N270–350 component. In b,c,e,f,h,i color denotes the scalp distribution of the potential differences between participants that reliably heard the continuous tone as continuous and those that reliably heard it as discontinuous. Electrodes with nominally significant correlations between performance and voltage in all subjects (p<0.05, uncorrected) are highlighted with bold circles.
