- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 80 Years
- Healthy Volunteers: f

Study Arms:
- Navigated TMS examination (Type: None): 20 patients with brain tumor in the vicinity of the central motor region scheduled for elective surgery will undergo pre-operative Navigated TMS examination to determine the localization of primary motor cortex and motor representation areas of specific muscles
