Figure 6. Ridge regression maps relating behavioral deficits to anatomical damage.
The color scale indicates weights (ω) determined by ridge regression for six behavioral factors, normalized to have a standard deviation of 1. Inset bar graphs show the percent of variance explained by lesion size alone (blue) or by lesion location (red). The dashed lines indicate significance thresholds determined by 10,000 random permutations of factor scores (5–6%).
