Purpose

This ClinicalTrials.gov entry corresponds to the Neural Basis of Human Working Memory protocol approved under Vanderbilt University Medical Center IRB #251231. This study investigates the neural activity underlying human working memory, via local field potential changes (macro level) and/or single neuronal spiking changes (micro level) from depth electrodes placed for invasive seizure monitoring. Subjects will complete neurocognitive tasks while neural recordings are collected. Some patients will complete neurocognitive tasks while stimulation is applied via depth electrodes. Further understanding the neural activity changes underlying normal and impaired working memory may help to identify novel diagnostic methods and treatments for impaired working memory and may support the use of stimulation for treatment of memory disorders.

ArmDescriptionAssigned Intervention
Epilepsy patients All participants will be patients with medically refractory epilepsy who have undergone depth electrode placement for stereo EEG monitoring for seizure localization. Participants will complete working memory tasks and EEG recordings will be concurrently collected from their depth electrodes. Some subjects will 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. Some subjects will complete working memory tasks with stimulation applied during task completion.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
