The major brain areas associated with the pleasurability of active scratching as revealed by GLM regression analysis.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Regions which were activated (red) or deactivated (blue) by scratching are depicted. __(solid line) = positive correlation; ---- (dashed line) = inverse correlation with pleasurability ratings. Box size for each area is proportional to the magnitude of Z scores obtained in the regression analysis.
