Default Mode Network Altered in Chronic Pain Caused by Cervical Spondylosis / 中国康复理论与实践

ABSTRACT

Objective To explore the changes of resting state default mode network (DMN) in patients with chronic pain caused by cer-vical spondylosis (CPCS). Methods 8 healthy controls and 10 patients accepted functional MRI scanning. Surface based DMN was extract-ed with independent component analysis (ICA). The functional connectivity of the components of DMN were discriminated with support vector machine (SVM) algorithm from the patients to the controls. Results The DMN connectivity was different in the patients from the con-trols in some of the component areas. Conclusion DMN of CPCS patients is disorder in multiple brain areas, which may be involved with dysfunction of perception processing, emotion and memory.
