Acupuncture has been worldwide used to against many disorders. However, the neural mechanism underlying acupuncture is still unclear. Many studies have investigated to the sustained effects using short-time acupuncture (no more than 6 min) for healthy subjects, which may be not long enough to satisfy the treatment effects. This is the first study, to our knowledge, to investigate small-world properties of brain functional networks modulated by long-time acupuncture(30 minutes). A tendency of increasing local efficiency was demonstrated in TEAS(transcutaneous electric acupoint stimulation) when compared with MTEAS(minimal TEAS),which suggest higher fault-tolerance for brain network after long-time acupuncture.
