About this trial
Adult epilepsy patients who are undergoing intracranial monitoring will participate in a simple behavioral task during the clinical recording period.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Epilepsy patients undergoing intracranial electrode monitoring for uncontrolled seizures.
no lesions identified in the participants' brains
capable of giving consent
Disqualifiers
seizure activity during task recording
electrodes in regions of interest are identified to be the seizure focus
task performance outside of the normal range as determined from online studies with healthy participants
Trial population
Epilepsy patients with intractable seizures who are undergoing clinical continuous intracranial recordings of the brain's electrical activity to assess the seizure focus location.

Treatments tested in this trial
Decision-making task
BehavioralPatients will be asked to play a decision-making game in which they hear a tone and must identify its source.
eye tracking
BehavioralPatients will have simultaneous eye-tracking performed while playing the decision-making game
Treatment groups
30 Participants
are divided into 1 treatment groupGroup A: Flexible Decision Making Task2 interventions
Trial outcomes
Primary outcomes
1
Pupil size changes with respect to task features
pupil size will be measured with a portable eye-tracking device and correlated with task features
Time frame
continuous recording during task, up to 30 minutes2
Behavioral Responses
Patient selects one of two choices on each trial using the computer keyboard
Time frame
Approximately 10 seconds per trial, up to 30 minutes total3
Intracranial electrode recordings to measure changes in brain activity during decision making
Intracranial neural recordings from patients who are implanted with electrodes for clinical purposes tha take place during the decision-making task
