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

Figure 1

Framing of dynamic casual model (DCM) structures. 16 dynamic causal modeling structures were defined as the common stimuli (i.e., driving input) but with different effective connectivity (i.e., propagation pathway); therefore, they were divided into 3 families. 3 ROIs (i.e., ROI S1 = somatosensory cortex, ROI AMY = amygdala, and ROI h = hypothalamus) were specified in the models from the left brain.
