Figure 4.
Language tasks eliciting BOLD activation in pre-supplementary motor area (pre-SMA also called language SMA). Axial view of nodes of BOLD activation for word generation (green), and sentence completion (purple) tasks for single individual. Overlapping nodes of activation are visible in the pre-SMA/language SMA. Depicted in the right-handed figure, language tasks eliciting BOLD activation in pre-SMA as destinguished from hand movement (blue) and lip movement (red) activations in SMA. These nodes may generally be distinguished by a line drawn perpendicular from the AC-PC line at the anterior commissure.
