Dendrogram (cluster tree) summarizing the results of complete-linkage cluster analysis of natural log-transformed, baseline-corrected amplitudes of motor evoked potentials at 5 to 50 minutes following continuous theta-burst stimulation (cTBS) of the left primary motor cortex in healthy individuals. The numbers on the abscissa indicate the subject numbers. Linkage distance is defined as the Euclidean distance between the farthest observations in each of the two linked subgroups. The tree structure illustrates two distinct patterns of response to cTBS by 12 individuals in Group 1 and nine individuals in Group 2.
