2D array of selected axial cuts for color‐coded activation intensities depicting the axial view of the mean activation maps for each group. Higher activations are in yellow color. Brain is oriented in radiological convention: right hemisphere on the left side. (a) Mean activation map for Group 1 with strong left lateralization of anterior (Broca) and posterior (Wernicke) clusters. (b) Mean activation map for Group 2 with higher mean intensity range than (a), which explains the better definition of supplementary motor area (SMA). (c) Mean activation map for Group 3 with an atypical right hemisphere dominant response, particularly, the anterior (Broca) cluster. Different intensity threshold (90% of the energy) was used for visualization purpose.
