The fMRI task included three different tasks shown to activate language-related areas in the brain: a paced verb-generation task, an antonym-generation task, and a semantic decision task. Five regions of interests (ROIs) in language-related areas were studied in addition to whole brain measures. A lateralization index was computed for each of these regions by taking the difference between the number of active voxels on the left and right and dividing by the sum of all active voxels.
