Acupuncture Induces Reduction in Limbic-Cortical Feedback of a Neuralgia Rat Model: A Dynamic Causal Modeling Study

Figure 3

Group differences of activation in block-design scan. The three rows displayed the results of the group difference in right-forelimb stimulation task at the three time points, respectively (i.e., premodeling, postmodeling, after 3 months of treatment). The warm tone represented greater activation of the EA group than that of the model group, whereas the cold tone represented weaker activation of the EA group than the model group. The -value was the -axis coordinate along the anterior-posterior axis referenced to a stereotaxic rat brain MRI template which has been aligned with the coordinates of Paxinos and Watson’s.
