Synopsis

Keywords: Brain Connectivity, fMRI (task based)The cross-modal plasticity was truly involved in theWorking memory (WM) that related to decision-making and memory processing after exercise intervention. However, we know little about the functional connectivity changes after the exercise intervention. The purpose of this study was to examine the cross modal plasticity and Granger causality connectivity among the internetwork in deaf children when performing a WM task before and after exercise intervention. Our results show that aerobic exercise intervention could improve working memory performance in reaction time and mean accuracy rate accompanied with increased internetwork casual flow connectivity.
