q3 i? From Time-1 to Time-2, children showed increased bilateral hippocampal activation and reduced dorsolateral prefrontal and parietal activation during addition problem solving. → Qin Shaozheng 2014

q3 · i? · associational · r2

Longitudinal block-design fMRI in 28 children; ROI analysis of anatomically defined hippocampus showed significant longitudinal increase in engagement, and 23 of 28 children showed increased hippocampal activation. No effect size is printed.

"Analysis of a priori anatomically-defined ROIs (Fig. 2c) spanning the entire long axis of the hippocampus also revealed a significant increase in hippocampal engagement (left: t(27)=2.39, P=0.02; right: (t(27)=3.26, P<0.01)"
