In current study, we analyzed resting-state fMRI data for the first time to evaluate the dysfunction of the sensorimotor network in migraineurs without aura by applying regional homogeneity (ReHo), amplitudes of low-frequency fluctuation (ALFF) and degree centrality (DC) analysis methods. The ReHo, DC and ALFF values were decreased in the S1 and PMC indicating the sensorimotor network dysfunction in migraineurs without aura. These changes may result in disruption of discrimination of sensory features of pain, thereby affecting nociception pathways. Non-invasive brain stimulation could be applied to sensorimotor network to modulate headache pain in future therapies.
