Fig. 7From: Spatiotemporal changes of optical signals in the somatosensory cortex of neuropathic rats after electroacupuncture stimulationEffects of the pre- and post-needle insertions on spatiotemporal fluorescence activities. a The peak activated fluorescence signals were not changed between pre- and post-needle insertions. b The maximal activated areas in S1 cortex were compared. Maximal activated areas between pre- and post-needle insertions were not significantly different (n = 4)Back to article page
