Proportion of selective sites as a function of the analysis interval. All intervals
were 200 ms in length here and were centered on the value indicated in the x-axis
in the plot.
For each interval, we computed the corresponding LFP measure (see below) and
performed an ANOVA analysis to measure whether the variability across the 78
pictures was significantly different from the variability within repeated presentations
of the same picture. The y axis indicates the propotion of sites where the p
value from the ANOVA analysis was < 0.01 (red), < 0.001 (green) or <0.0001
(blue). The dashed line shows the maximum of each curve.
