Figure 2From: Regional differences in trait-like characteristics of the waking EEG in early adolescenceRate of clustering in central and occipital derivations. Rate of clustering is depicted for central and occipital derivations. Each bar represents the results of the cluster analysis for a given derivation in the eyes open and closed conditions with the percentage of participants who cluster correctly noted on top. The y-axis shows the number of participants who cluster correctly. Significant differences (p<0.05; n.s., non-significant) were analyzed using a χ2 test.Back to article page
