Figure 3b: shows typical activation patterns observed during silently generating an animal name (two left panels) and overtly generating an animal name (two right panels). Note that Broca’s area was not activated during overt animal-name generation (right, top panel), but was activated to a large extent during silent animal-name generation (left, top panel). Broca’s right homologue (RH) varied in the opposite direction, showing greater activation during overt speech than silent speech.
