Acupuncture is an important component of Traditional Chinese Medicine (TCM) with a long history. Although there are a number of different acupuncture manipulations, the relationship between the evoked electrical signals and manipulations is rarely investigated. So an experiment is performed that acupuncture at Zusanli acupoint by four acupuncture manipulations with different frequency to obtain the spike trains at spinal dorsal horn, and then study the correlation between manipulations via neural system outputs. Because the neural information transmission underlies the temporal spike timing, the concepts of interspike intervals (ISI) and firing rate (FR) are introduced. First, distinguish and correlation between different twirling frequencies is obtained through ISI sequences of the evoked electrical signals. Then the variation trend of the firing rate with the twirling frequency is discussed.

As well-known, the science of acupuncture and moxibustion is an important component of Traditional Chinese Medicine with a long history. Although there are a number of different acupuncture manipulations, the method for distinguishing them is rarely investigated. With the idea of the interspike interval (ISI), we study the electrical signal time series at the spinal dorsal horn produced by three different acupuncture manipulations in Zusanli point and present an effective way to distinguish them. Comparing with the traditional analysis methods, like phase space reconstruction and largest Lyapunov exponents, this new method is more efficiently and effective.
