Distribution maps of theta activity in both MENS and POV phases. (a) Theta activation map of one representative PDM subject. (b) Theta activation map of one representative CON subject. Color of each voxel denotes the activation index of theta activity. (c) Distribution maps of increased theta activity in PDM group compared to CON group (uncorrected p < 0.01, cluster size k > 50), superimposed on T1-weighted template images. Brain regions revealed in our results (red: MENS, blue: POV) include the parahippocampal gyrus, insula, sensorimotor cortex, middle cingulate cortex, and prefrontal cortex. PDM, primary dysmenorrhea; CON, healthy controls; MENS, menstruation; POV, periovulatory.
