FIGURE 2.

Example of functional activations seen on a phonemic fluency language task (threshold of minimum correlation r = 0.5 (uncorrected p < 0.0001), minimum cluster size of 20 voxels (1280 mm³) administered visually in a healthy subject (43 years old male). In this type of task, the subject is asked to silently generate words starting with a specific letter. The fMRI language activation map is overlayed on the subject’s pre-contrast T1-weighted 3d images after skull stripping. BA, Broca’s area; EA, Exner’s area; pre-SMA, pre-supplementary motor area; VA, visual activation; WA, Wernicke’s area.
