Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This ClincialTrials.gov record originally corresponded to the protocol approved under IRB # 202370. The study was expanded to include stimulation and recordings approved under new IRB #211037. The participant data originally acquired from IRB# 202370 will be included in this new record:

This study seeks to better understand the neural activity underlying neuro cognitive disorders. Resting state local field potential recordings will be collected from medically refractory epilepsy patients implanted with depth electrodes for seizure localization, and metrics of neural activity will be correlated with psychiatric symptoms as measured from questionnaires. Subjects will also participate in neuro cognitive tasks while neural recordings are performed, and/or receive neural stimulation through implanted depth electrodes. A better understanding of disordered neural activity underlying neuropsychiatric disorders may additionally contribute to novel methods for diagnosing, treating, and preventing these diseases.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Epilepsy patients

All participants will be patients with medically refractory epilepsy undergoing depth electrode placement for seizure localization. For this study, participants will complete psychiatric questionnaires measuring depression, anxiety, obsessive compulsive disorder, and impulsivity, and EEG recordings will be collected from the depth electrodes while subjects rest quietly. Some subjects will also participate in neuro cognitive tasks while neural recordings/stimulation are performed. Some subjects will also undergo macro-micro electrode implantation as a part of their SEEG implantation procedure for the purpose of EEG macro (local activity) and micro (single-unit) recordings.
