Study Summary
Purpose: To investigate the electrophysiological correlates of human cognition and affective processing. Participants: Drug-resistant epilepsy patients undergoing epilepsy surgery cortical mapping with continuous electrocorticography (ECoG) with intracranial electrodes. Procedures (methods): Participants will perform computer-based cognitive and affective processing tasks during routine long-term monitoring. Intracranial EEG will be collected during the task
Primary Outcome
Spectral analysis of electrophysiology data will be performed using multi-taper fft and wavelet transforms. The measures will be compared between different epochs within the tasks to determine what oscillations are modulated by the task. The correlation between the measures described above and the task performance will also be estimated.
Interventions
- BEHAVIORAL Working Memory Task
- BEHAVIORAL Reward Learning Task
- BEHAVIORAL Facial Emotion Recognition Task
