Timing of Acupuncture during LTP-Like Plasticity Induced by Paired-Associative Stimulation

Figure 3

(a, c) Amplitude modulation of MEPs in the left FDI muscle following acupuncture during the different phases of the experimental protocol and (b, d) amplitude modulation of MEPs in the left FDI muscle following sham acupuncture groups during the different phases of the experimental protocol. The “Before” panel indicates the baseline before acupuncture application, whereas the “In” panel denotes the average values across participants for the experiments in which the needle was in situ for 30 minutes. The “Off” panel refers to the data recorded after the needle removal within 20 minutes. Graphical illustration of the mean MEP amplitudes over the whole acupuncture is presented. The asterisks indicate the statistical significance compared with the baseline. The levels of significance are as indicated in the text.
