Figure 2. Interactive specialization of IPS circuitry.
The left IPS connectivity with the (A) right fusiform gyrus (FG) in the VTOC and (B) right SPL, and (C) right IPS increases with age, while the left IPS connectivity with the (D) left DLPFC, (E) left VLPFC, and (F) left insula decreases with age during arithmetic problem solving. Target brain regions of left IPS circuits positively and negatively associated with age are shown in orange-yellow and light blue, respectively. Line plots show hierarchical linear modeling (HLM) fits for target brain regions from the left IPS to whole-brain connectivity analysis. Model fits and individual trajectories are shown in thick black and light gray lines, respectively. L: Left; R: Right. Other abbreviations are the same as in Figure 1. Adapted from Battista et al.
