Characterizing electrical signals evoked by acupuncture through complex network mapping: A new perspective on acupuncture

The electrical signals are obtained in spinal dorsal root after different manipulations of acupuncture (MA) being taken at the ‘Zusanli’ point of the experiment rats. After combining the analysis of the data generated from neuronal network model and that evoked by acupuncture, it is found that features of neuronal chaotic rate time series induced by periodic stimuli can be characterized by complex network approach. The features of signals evoked by MA ‘nb’ ‘nx’ (twisting) and MA ‘tb’ ‘tx’ (lifting and thrusting) are shown to be different according to the topologies of the mapped networks. This study provides us a new perspective on the analysis of acupuncture and may give potential helps on clinical treatment.
