Figure 7. Interactive specialization of parietal circuits in response to math training.
A. Math training increases performance efficiency in arithmetic problem solving in third grade children. B. Training increases functional connectivity of the IPS with the right VTOC, left hippocampus (HIPP), and right inferior frontal gyrus (IFG). C. Training-related performance gains are associated with increased connectivity between the IPS (but not angular gyrus [AG]) and right hippocampus. D. Training leads to differential functional connectivity patterns of IPS vs. AG. Post-training, compared to pre-training, IPS shows greater functional connectivity with the right frontal pole, left middle frontal gyrus (MFG), and left middle temporal gyrus (MTG), while AG shows greater connectivity with the right precentral gyrus and right occipital cortex. *p < .05.
