Individual analysis of the task-related activation in the left S1 (green), left LO (blue), and V1 (red). (Top) The foci with significant activation during Mah-Jong tactile discrimination by a non-expert (left) and an expert (right) were superimposed on the transaxial images of the T2-weighted high-resolution MRI of each subject. Blue lines indicate the projection of the yz and xz sections in standard stereotaxic space at the MNI coordinates indicated in each image. (Bottom) The time courses of the MR signal changes of each location (V1 in red, LO in blue, and SM1 in green) were plotted. The mean value of the time-course data of each plot was centered to zero.
