Validation of TMS motor mapping by CSM. Presurgical TMS-derived motor mapping in a 2.3-year-old female with tuberous sclerosis complex type 2. (A): TMS localized motor cortex in the right hemisphere in the precentral gyrus in the vicinity of a tuber. (B): The child underwent subdural grid placement, and the epileptogenic focus was localized to be anterior to the motor cortex. (C): The child underwent right anterior frontal lobectomy including the epileptogenic focus. Post-operatively, the child moves all extremities equally with normal bulk and strength and uses either hand to reach for an object.
