Fig. 3: Similarities in key activated regions across number-arithmetic and reading for adults and children.

Conjunction analyses revealed significant overlaps between number-arithmetic and reading for both lower- and higher-level contrasts. a For adults, processes with lower-level contrasts showed overlaps within the inferior frontal gyrus (IFG), while processes with higher-level contrasts additionally engaged the dorsomedial prefrontal cortex and dorsal anterior cingulate cortex (dmPFC/dACC), as well as the anterior insula (AI), across domains (see Tables S17). b For children, both lower-level and higher-level processes showed significant overlaps in the dmPFC and AI across domains, similar to adults. Additionally, lower-level and higher-level processes engaged the superior parietal lobule (SPL) and the precuneus (PCu), respectively. (see Tables S18). Note, the color scales indicate the estimated ALE values: SFG superior frontal gyrus. L left, R right.
