Fig. 4. PPI of the right ACC. (A) All areas are shown that receive a signiﬁcant context-dependent contribution from right ACC during visuospatial decisions, projected on the same rendered brain as in Fig. 1. Right ACC signiﬁcantly increased its inﬂuence on posterior (28/–72/48, t max 4.49, P 0.015, corrected) and anterior parts of the right IPS (42/–42/44, t max 4.63, P 0.034,corrected) during visuospatial decisions. Note the speciﬁcity of this result: Even when the threshold was reduced to P 0.05, uncorrected, no other signiﬁcant clusters were found throughout the brain. (B) This schema summarizes the negative ﬁndings for right ACC: As indicated by the gray dashed lines, right ACC shows no context-dependent contributions to any left-hemispheric area during visuospatialdecisions and none to any left- or right-hemispheric area at all during letter decisions.
