Eligibility

Inclusion Criteria:

• diagnosis of Epilepsy

• undergoing neuromodulation therapy with clinically implanted neuromodulation devices (DBS, RNS)

• followed in the outpatient epilepsy clinic

Exclusion Criteria:

• pregnant women

• active psychosis, major depression, or suicidal ideation in the preceding year

• Intelligence quotient (IQ) less than 70 as measured by clinical neuropsychological evaluation

• Do not agree to share their medical records for research purposes

Related Conditions & MeSH terms

• Drug Resistant Epilepsy
• Intractable Epilepsy

Intervention

Device:
• RNS/DBS activation
This will be performed to study the EEG responses to DBS/RNS stimulation electrical pulses. The stimulation frequencies will be sequentially increased and each stimulation will last for 2 minutes.There will be a 1-2 minute wash out period after each trial.

Primary	Change in amplitude of evoked potentials metrics as assessed by the scalp EEG		Baseline, Intra intervention (about 20 minutes after baseline)
Primary	Change in amplitude of evoked potentials metrics as assessed by the scalp EEG		Baseline, post intervention (about 2 hours after baseline )
Primary	Change in latencies of evoked potentials and phase synchronization metrics recorded as assessed by the scalp EEG		Baseline, Intra intervention (about 20 minutes after baseline)
Primary	Change in latencies of evoked potentials and phase synchronization metrics recorded as assessed by the scalp EEG		Baseline, post intervention (about 2 hours after baseline )
