Brain plasticity may take place during oncogenesis,Resting-state functional connectivity MRI (fc-MRI) is an effective method to study impaired brain plasticity. However, tumors in or adjacent to primary motor cortex without motor symptoms may disrupt the functional connectivity of the brain. The reason behind this is still unclear. To observe the changes in motor functional plasticity of patients with brain tumor, we compared the functional connectivity between bilateral primary motor cortex (PMC) and supplementary motor area (SMA) of healthy controls and patients with brain tumor. A significant linear correlation between LPMC-SMA and RPMC-SMA was presented in the normal control group. However, no significant correlation was observed between LPMC-SMA and PRMC-SMA in the patient group.
