Assessment
Primary outcomes
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).

Interventions/Control_1
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 during cognitive tasks (visual, auditory, and tactile stimuli). Furthermore, evaluating the changes of cognitive performances by stimulating the cortical region. The parameters of stimulation are based on the conventional clinical functional mapping protocol.
