Group mean image data for the six slices (slice1 is most anterior; slice 6 is most posterior). Strong activation of the MFG can be seen for both count and button press conditions in slices 1–4 forTargets but not for Novels. Some activation by Targets of the inferior frontal gyrus bilaterally can be observed in the most posterior slice. As for the MFG, this activation is greater on the right thanleft. Some activation by Novels can be observed in posterior slices 4 and 5 in the right inferior frontal gyrus.
