FIG. 4.

Active voxel counts in 3 fMRI language tasks in 4 ROIs by tumor location. The results were obtained from 4 patient groups that differed based on their tumor location: the anterior right hemisphere, left anterior hemisphere, posterior right hemisphere, and posterior left hemisphere. The 4 ROIs are Broca’s area (red bars), Wernicke’s area (blue bars), the right hemisphere homolog of Broca’s area (green bars), and the right hemisphere homolog of Wernicke’s area (yellow bars). Patients with an anterior left hemisphere tumor had decreased active voxel counts in Broca’s area and slightly increased voxel counts in the right hemisphere homolog of Broca’s area. Patients with the left posterior lesions had slightly decreased activity in Wernicke’s area.
