Official title
Behavioral and Pharmacological Manipulation of Time Cell Activity in the Human Mesial Temporal Lobe
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to learn about the effects of scopolamine (an anticholinergic drug) on areas of the brain involved in memory, and changes it may have on brain activity. The investigators will do this by testing epileptic patients who are already undergoing intracranial surgery for seizure monitoring, and measuring the activity from the brain areas being assessed. The main questions it aims to answer are 1) whether scopolamine changes memory activity solely at encoding (the time when the person perceives and determines to remember an item or event) as has previously been found, or if it also can selectively impact retrieval (when the item or event which has been processed is recalled or remembered), and 2) what the nature of the brain activity changes is. Participants will complete two treatment arms. One of these will be with the drug, and the other will be with a saline solution, so that the participants are unaware which session the actual drug has been received. Patients will complete a verbal and/or spatial task each of the two days. An anesthesiologist will administer either the drug or the saline at a critical point which addresses both of the research questions. Researchers will compare the brain activity between the two treatment arms to determine what brain activity changes, and at what time point during memory formation.
