Additional Evidence for the Sustained Effect of Acupuncture at the Vision-Related Acupuncture Point, Gb37

Abstract

Owing to the sustained effect of acupuncture, standard GLM analysis may be unsuitable for 'on-off' design acupuncture studies and lead to uncertain and contradictory results. The findings from this study suggest that acupuncture at GB37 can induce complex brain activity in the vision cortex. The state-related neural signal may reflect one of the significant characteristics underlying acupuncture.
