Tai Chi Exercise Improving Resting-State Functional Connectivity between Prefrontal and Medial Temporal Lobes
The prefrontal cortex and medial temporal lobe are connected and collaborate in memory processes.Their connections are susceptible to aging and are an important cause of impaired memory function.METHODS:In this study,22 participants from the Yang's Tai Chi expert group and 15 participants from the Tai Chi novice group were selected to compare the functional plasticity of the two regions in the resting state between the expert group and the novice group by comparing the connectivity between the default network regions and the connectivity between the prefrontal lobe as the region of interest corresponding to the whole brain in the expert and novice groups,and then to investigate the effects of long-term Tai Chi training on these two brain regions.Results:(a)Compared with the Tai Chi novice group,the Tai Chi expert group performed better in situational memory;(b)long-term Tai Chi practice could effectively improve the functional connectivity between the prefrontal lobe and the medial temporal lobe;(c)the strength of the functional connectivity between the prefrontal lobe and the medial temporal lobe areas was correlated with situational memory performance.Conclusions:(a)Compared with the Tai Chi novice group,the Tai Chi expert group showed better performance in situational memory;(b)long-term Tai Chi practice was effective in improving resting-state functional connectivity between the prefrontal lobe and medial temporal lobe,and this effect was closely related to situational memory performance.
