Fig. 6From: Spatiotemporal changes of optical signals in the somatosensory cortex of neuropathic rats after electroacupuncture stimulationSpatiotemporal activities of sham EA stimulation in neuropathic rats. Sham EA stimulation was characterized by EA stimulation at nonacupoint locations (a) Each activated signal in pre- or post-sham EA stimulation was detected after electrical stimulation of the hind paw in nerve-injured rats. After sham EA stimulation, the enlarged and propagated activated area did not reduce. b The peak activated fluorescence signals did not change after sham EA stimulation. c The average of peak fluorescence has shown continuance activated pattern. d Time-dependent observed maximal activated area in S1 cortex is presented (n = 5)Back to article page
