b) Contrast (refl-self > refl-known) & (refl-self > refl-unknown) & (refl-self > perc-self)
Insula/inferior frontal gyrus L (Figure 1A) 13/44 -38 15 8 2495 3.9
Sup. frontal gyrus/DMPFC R (Figure 1B, 2A) 6 9 1 53 1964 4.1

Posterior cingulate cortex (Figure 1D) 23/24 2 -19 34 636 4.2

Activity during self-reflection significantly larger (random effects analysis, p > 0.005, p < 0.01 Monte Carlo simulation corrected) than in the known and the unknown reflection conditions.

Activation as in a) but also larger in the refl-self than in the perc-self condition.
