Functional connectivity alteration during imagination after motor imagery learning using real-time fMRI based on graph theory

摘要：

　　Real-time functional magnetic resonance imaging technology(real-time fMRI)has attracted increasing attention in recent years due to its advantage that subjects can regulate their performance through feedback.Previous studies illustrated that subjects can improve their performance using real-time fMRI.However,the influence of real-time fMRI on human brain is not clear yet.Motor learning,including motor execution(ME)learning and motor imagery(MI)learning,is an important method for motor function rehabilitation and motor skill learning.Particularly MI learning has potential application for those movement disorders.So our study aimed to investigate the influence of MI learning that under real-time fMRI on the functional connectivity of imagination task by using graph theory.The results showed that the degree of right posterior parietal lobe(rPPL)and the function connectivity between rPPL and bilateral premotor area(PMA)have decreased in imagination task in the experimental group.These finding has provided new evidence that real-time fMRI is effective and can provide a multi-dimensional data support for the MI learning.
