4.2. Acupuncture Alters Brain's Dynamic Functional Network Connectivity
After treatment, the TATG group showed a reduced mean dwell time in state 3, as manifested sparse connections within and between brain functional networks. Previous studies demonstrated that such weakly connected state resembled stationary functional connectivity, representing the average of a great number of additional states that were infrequent to be separated or insufficiently distinct [In addition, we found attenuated connectivity between SMN and FPN in state 3 in the TATG group after treatment. SMN is involved in perceptual and motor function, and FPN participates in many cognitive tasks consisting of attention, working memory, and motor control [Besides, we found both fraction time and mean dwell time in state 1 that had an increasing tendency after In terms of sham acupuncture treatment, we found increased mean dwell time, as well as elevated FC within FPN in state 2 after treatment. FPN is mainly involved in the cognitive control process such as attention and memory [
