Fig. 3

Illustration of the abnormal thalamic-level Granger-causal model in MWCA compared with the two control groups. a Abnormal effective connectivity pathways associated with the Left PTH. b Abnormal effective connectivity pathways associated with the right PTH. The node size is represented by absolute T-value of corresponding cluster. The red and blue flags represent the positive and negative correlation between the strength of abnormal effective connectivity pathway and ASC (index of allodynia severity), respectively. DLPFC, dorsolateral prefrontal cortex; dmPFC, dorsal medial prefrontal cortex; HC, healthy control; L, left; MWCA, migraineurs with cutaneous allodynia; MWoCA, migraineurs without cutaneous allodynia; PTH, posterior thalamus; R, right; vmPFC, ventral medial prefrontal cortex
