Electrophysiologic Studies of Cognition in Epilepsy Patients

Computer-based tasks designed to evoke changes in interoceptive attention, arousal and anticipation will be completed. The first asks patients to attend to their heartbeat to manipulate interoceptive attention. The second asks patients to judge affective pictures to manipulate states of arousals. The third engages patients in a probabilistic reward-learning task, or gambling task, and anticipate the outcomes of risky decision-making. A final task guides patients to slow their breathing to 6 breaths per minute.
