Brain plasticity is a continuous process during slow-growing tumor formation, which remodels neural organization and optimizes brain network function. In this study, we aimed to investigate whether motor function plasticity exists in patients with slow-growing brain tumors located in or near to motor areas, and who exhibited no motor deficits. We use resting-state functional magnetic resonance (rs-fMRI) data in the frequency domain, and investigate the relationship between the low frequency band shift and motor functional plasticity changes in patients with brain tumor, and achieve a better understanding of underlying mechanisms.
