Result maps of mean searchlight. Radii = 3 (top left), 2 (top right), 1 (bottom left) and 0 (bottom right). When the radius is set to the maximum value of 3, the regions were strongly concentrated in the right middle temporal gyrus, right cerebellum and left middle occipital gyrus. When it is 2, relatively, a wide range of brain areas were sensitive; particularly activated were the right middle temporal gyrus, right inferior temporal gyrus, left middle occipital gyrus, left inferior temporal gyrus as well as left inferior occipital gyrus. With the radius narrowed down to 1, informative voxels were scattered in the right middle temporal gyrus, right fusiform gyrus, left middle occipital gyrus, left middle temporal gyrus, left inferior occipital gyrus and left supramarginal gyrus. And finally, when removing the adjacent voxels from the searchlight scope (radius = 0), brain informativity was shown in the right middle temporal gyrus, left superior frontal gyrus, right fusiform gyrus, right inferior temporal gyrus and left supramarginal gyrus.
