	Brodmann area	Mean X	Mean Y	Mean Z	Cluster size mm³	t-max
Insula/inferior frontal gyrus R	13/47	-36	12	0	833	4.1
Insula/inferior frontal gyrus L	13/47	-36	12	0	833	4.1
Anterior cingulate cortex R (Figure 3A, 2 C)	24/32	2	20	23	5968	5.3
Superior parietal gyrus R	7	25	-61	43	3891	4.6
Inferior parietal lobule R (Figure 3B, 2D)	40/1/2/3	56	-28	35	938	4.0
Temporo-occipital junction R	19/20/37	45	-56	-7	6462	6.4

Given are brain regions resulting from the contrast (perc-self > perc-known) & (perc-self > perc-unknown) with activity significantly larger during self-perception and lower than in the known and the unknown condition (random effects analysis, p > 0.005, p < 0.01 Monte Carlo simulation corrected). Clusters with merely deactivations in all conditions in the presentation period were not considered (e.g. bilateral superior/middle temporal gyrus). Abbreviations: R right, L left, med medial. Reported are the mean Talairach coordinates of the respective clusters.
