Figure 3. Comparison of brain activation in sentence processing and nonlinguistic sequence mapping tasks. Subjects read visually presented sentences and nonlinguistic sequences presented one word/element at a time, and performed grammaticality/correctness judgments after each, responding by button press. Red areas indicate regions activated by both tasks, including a prefrontal network that involves BAs 44, 46, 9, and 6. Green areas indicate cortical regions activated exclusively in the sentence processing task, including BAs 21, 22, 47, and 45. From Hoen et al. (2006) with permission.
