The localization of motor cortex in tumor patients plays an important role in presurgical planning and risk assessment. Therefore, over the past few years, resting state fMRI and task-based fMRI have been used together to localize the motor cortex. However, it is worth noting that whether the RS-fMRI can serve as a promising alternative to the task-based fMRI in the mapping of motor cortex still remains pending due to the insufficient dataset of tumor patients. In this work,we aim to evaluate the possibility of employing the RS-fMRI as a proper and robust tool for mapping motor cortex in presurgical patients.
