Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: People have 2 memory systems. One helps them learn skills and the other helps them learn facts. Repetitive transcranial magnetic stimulation (rTMS) uses electric currents to activate brain cells. This can make small changes in how brain systems operate. Researchers will use rTMS to change how memory systems work and to see if changing one system causes the other to change too. This could help find ways to improve learning and memory in people with memory disorders. Objective: To learn how different memory systems work with each other. Eligibility: Healthy adults ages 18-40 who are not pregnant Design: Potential participants will be screened with a neurological exam if they have not had one from NINDS in the past 2 years. They may have urine tests. Eligible participants will have 5-10 visits at NIH. Each visit will last 1-6 hours. Visits 1-4 will each take place 1 day apart. At visit 1, participants will have an MRI and take memory tests. For MRI, they will lie on a table that slides in and out of a cylinder that takes pictures of their brain. They will also have rTMS. For rTMS, a metal coil is held on their scalp. Brief electrical currents pass through the coil. At visits 2 and 3, participants will have rTMS. At visit 4, participants will have an MRI and do memory tests. About a week later, participants will have visit 5. They will have an MRI and do memory tests. Participants may be asked to have more visits if any technical problems occur. Participant involvement will last 2 weeks. ...
