Eligibility criteria

Inclusion

Subjects are selected on the basis of intractability of their seizures to medical intervention by antiepileptic drugs and following a noninvasive workup that indicates the patient would be an excellent candidate for resective surgery.

Exclusion

Patient is under the age of 5
  • Decrease in seizure frequency after epilepsy surgical treatmentup to 4 weeks

    We are interested in identifying specific factors that predict the effects of epilepsy surgery on seizure control. We will start by assessing electrographic (seizure foci and spread), imaging (cortical volume, presence of structural pathology), and surgical (extent of surgical resection) factors.

  • Change in electrophysiological markers (local field potential power and phase) during cognitive tasksup to 4 weeks

    We will compare brain recordings during distinct cognitive functional states, as defined by performance and participation in cognitive tasks (typically task vs resting state). Power and phase measures isolated from local field potentials in implanted electrodes will be assessed. Neuronal firing rates will also be assessed.

  • Change in memory performanceup to 4 weeks

    We will measure the change in memory performance in memory tasks (percent of items correctly recalled).

  • Change in decision-making performanceup to 4 weeks

    We will measure the change in performance (reaction time and accuracy) in decision-making tasks.

  • Change in sensory perceptionup to 4 weeks

    We will measure the change in performance in auditory/visual perception tasks (percent of items correctly perceived).
