Reasoning about relations that are easy to visualize but hard to envisage spatially activated areas in the secondary visual cortex, V2 (43). The figure shows the significant activation from the contrast between such problems and abstract problems (in terms of the color scale of z values of the normal distribution) with the crosshairs at the local peak voxel. Upper Left: Sagittal section, showing the rear of the brain to the left. Lower Left: Horizontal section, showing the rear of the brain to the left. Upper Right: Coronal section, with the right of the brain to the right. [Reproduced with permission from ref. 43 (Copyright 2003, MIT Press Journals).]
