Modularization of memory and reward-motivation related regions on MSTs. The MSTs of control rats at the ages of 4 (A) and 6 weeks (B), and of ADHD-model rats at the ages of 4 (C) and 6 weeks (D) were visualized. The modularization score was counted as the number of directly connected edges between nodes belonging to the memory-related (blue) or the reward-motivation-related (red) regions. Abbreviations: ACC, anterior cingulate cortex; ADH, anterodorsal hippocampus; CP, caudoputamen; INS, insular cortex; L (small), left; mPFC, medial prefrontal cortex; MST, minimum spanning tree; M, memory-related regions; PVH, posteroventral hippocampus; R, reward-motivation-related regions; R (small), right; RSC (retrosplenial cortex); w.o., weeks old.
