Study Summary
Background: * Direct current (DC) brain polarization is a technique in which very weak electricity is applied to the head. Doctors have used DC polarization for many years on patients and healthy people with no known serious side effects. Earlier, researchers found that DC polarization can temporarily improve the ability of healthy people to think of certain words. * A disadvantage of existing methods of DC polarization is that they use large electrodes and the current spreads over a large area of the brain. This makes it difficult to target particular brain areas. High-density DC polarization uses several small electrodes to focus the current in a small area of the brain. This study will test high-density DC polarization for the first time in humans. Objectives: * To see how well high-density direct current polarization works in the brain. * To test a new method of performing direct current brain polarization. Eligibility: \- Healthy, right-handed adults, ages 18 and older, who have no history of neurological or psychiatric illnesses. Design: * After an initial screening visit with clinical examination, participants may be assigned to one or both experiments of the study. * Experiment 1: Participants will have electrodes placed on the left side of their heads, and will be asked to say aloud as many words as they can think of that begin with certain letters. After the high-density DC polarization current is turned on and run for 10 minutes, participants will say words beginning with a different set of letters and perform reaction time and thinking speed tests. Some participants will receive real polarization and others will not, although all participants will be told that they are receiving the polarization. * Experiment 2: Participants will have DC brain polarization performed with transcranial magnetic stimulation (TMS), which uses magnetic pulses to activate nerve cells in the brain. We will use TMS to help us understand how far the effect of DC polarizati
