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

Figure 6

Group effective coupling differences of postulated cortically driven limbic network. (a) Schematic representation of the result of the winning family. (b) Schematic representation of interacting pain matrices. The red sphere represents the somatosensory cortex, the yellow one is the amygdala, and the blue one means the hypothalamus. (c) Results of group analysis of the effective connectivity between the model and EA groups. Each mini-graph represents the result of each connection in the winning model (i.e., h-S1, AMY-S1, S1-h, S1-AMY, h-AMY, and AMY-h).
