The goal of the study is to explore the neural representations of sensory stimuli and cognitive processes by measuring neural activity and stimulating the cortex and subcorticalareas.
Efficacy
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).
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.

Participants: Patients with epilepsy implanted with chronic subdural or depth electrodes for epileptogenic focus surgery.
Duration: 2 ~ 4 weeks (1~3 hours / day)
Study: Measuring neural activities from the cortex and subcortical area during cognitive tasks (visual, auditory, and tactile stimuli). Furthermore, evaluating the changes of cognitive performances by using electric stimulation to the cortical and subcortical areas. The parameters of stimulation are based on the conventional clinical functional mapping protocol.
