- Primary Outcome Measures
Name Time Method The neural activities during cognitive tasks and the behavioral performances of the cognitive tasks by stimulation of the cortex will be evaluated. The evaluation will be performed before epileptogenic focus resection surgery (~4 weeks).
- Secondary Outcome Measures
Name Time Method 1. The neural activities during cognitive tasks and the behavioral performances of the cognitive tasks by stimulation of subcortical areas will be evaluated. The evaluation will be performed before the implantation of the stimulation device used in deep brain stimulation therapy (~2 week). 2. In patients undergoing epileptic focal resection, device implantation for deep brain stimulation therapy, brain tumors, or cerebrovascular disease surgery, functional magnetic resonance imaging are used to assess the activity of cortical and subcortical areas during cognitive tasks and at rest. Evaluations will be performed before the surgery, and 1 month and 6 month after the surgery.
