Figure 6
(a) Scatter plot between baseline-normalized cued response time and the Theta-Alpha power ratio, and linear regression fit for the “nondepressed” (GDS < 15) and “depressed” (GDS ≥ 15) QEEG groups. (b) Dendrogram plot of the hierarchical cluster tree from the data set—average slope of the Theta-Alpha power ratio versus average slope of baseline-normalized cued response time—providing three clusters shown with blue, red, and green colored linkages.
