Study Summary
Background: * Individuals who have schizophrenia are significantly more likely to smoke than the general population, which leads to increased smoking-related illnesses and high rates of nicotine dependence. Research suggests that high rates of smoking and nicotine addiction in people with schizophrenia are related to the fact that nicotine temporally improves performance in several cognitive tasks, including sensory gating, long-term memory, and visual tracking-all of which are affected by schizophrenia. * Smoking among schizophrenia patients may be a form of self-medication, since nicotine may temporarily treat and improve cognitive deficits caused by schizophrenia. Researchers are interested in studying the effects of nicotine on the brain activity of individuals with schizophrenia to better understand how nicotine affects the brain regions connected to memory, visual tracking, and attention. Objectives: * To identify specific brain regions involved in the anticipatory learning deficits found in schizophrenia patients who smoke. * To determine whether and how nicotine enhances performance in these regions. Eligibility: \- Smokers (at least 10 cigarettes per day) between 18 and 50 years of age who either are healthy volunteers or have been diagnosed with schizophrenia/schizoaffective disorder. Design: * Participants will be asked to avoid consuming alcohol and restrict consuming caffeinated beverages for 24 hours before the study days. Participants will provide urine and breath samples at the start of the study to be tested for chemicals that may interfere with the study. * The study will require two to four visits, with two fMRI sessions and other visits for a clinical interview or training. Participants will have a training session with a possible mock MRI scan to learn how to do tasks that track eye movement and measure ability to pay attention. * During the fMRI scanning sessions, participants will receive either a nicotine patch or a placebo patch wit
