Fig. 2. — Representative transaxial brain maps of magnitude of quadratic coefficient calculated voxelwise by least-squares optimization of the quadratic function , where Zuckerman’s sensation-seeking score is the explanatory variable and the binding potential of each voxel is the dependent variable. The color codes the negative coefficient of the inverted-U convexity. Eight pairs of sections with z axis coordinates are shown with and without superimposition on the standard MRI brain atlas of the MNI for precise anatomical identification. The color scale covers the range of negative coefficient values between 0.001 and 0.01.
