An Examination of Cognitive and Sensorimotor Processes in Patients With Epilepsy

Subjects will perform cognitive tasks during MRI scanning sessions to gather data about cognitive functions.

Subjects will have a neuropsych evaluation as part of their standard of care for surgery. The research team is asking the subject to release their neuropsychological evaluations for analysis.

Subjects will typically have between 100-300 electrodes implanted as part of their surgery. Additional electrodes will be implanted that are able to record from smaller, more specific parts of the brain. This will allow for better understanding of how the brain is wired.

Intracranial or extracranial electrodes will be used to deliver electrical brain stimulation (amplitude 0.5-8.0mA) or sham stimulation of between 0.4 and 3000 milliseconds during cognitive task periods.
