Background: When people have a stroke, they often have difficulty moving their arms and hands. Transcranial magnetic stimulation (TMS) can improve how well people with and without stroke can move their arms and hands. But the effects of TMS are minor, and it doesn t work for everyone. Researchers want to study how to time brain stimulation so that the effects are more consistent. Objective: To understand how the brain responds to transcranial magnetic stimulation so that treatments for people with stroke can be improved. Eligibility: Adults ages 18 and older who had a stroke at least 6 months ago Healthy volunteers ages 50 and older Design: Participants will have up to 5 visits. At visit 1, participants will be screened with medical history and physical exam. Participants with stroke will also have TMS and surface electromyography (sEMG). For TMS, a brief electrical current will pass through a wire coil on the scalp. Participants may hear a click and feel a pull. Muscles may twitch. Participants may be asked to do simple movements during TMS. For sEMG, small electrodes will be attached to the skin and muscle activity will be recorded. At visit 2, participants will have magnetic resonance imaging (MRI). They will lie on a table that slides into a metal cylinder in a strong magnetic field. They will get earplugs for the loud noise. At visit 3, participants will have TMS, sEMG, and electroencephalography (EEG). For EEG, small electrodes on the scalp will record brainwaves. Participants will sit still, watch a movie, or do TMS. Participants may be asked to have 2 extra visits to redo procedures.

Background: - Two ways to study the brain while people are moving are near-infrared spectroscopy (NIRS) and electroencephalography (EEG). NIRS uses light to look at blood flow in the brain when it is active. EEG records electrical activity in the brain. Both have been used safely for many years, even in very young children. NIRS or EEG can be used while a person is moving to show which parts of the brain are the most active. Researchers want to use NIRS and EEG to study brain activity during movement in people with cerebral palsy and healthy volunteers. Learning more about how people with and without cerebral palsy use their brain to control their muscles may lead to new ways of training people with cerebral palsy to move better. Objectives: - To study how the brain controls body movement in people with and without cerebral palsy. Eligibility: - Individuals at least 5 years of age who have cerebral palsy. - Healthy volunteers at least 5 years of age. Design: - This study has three parts. People with cerebral palsy will be selected for all three. Healthy volunteers will be asked to do only two of them. Everyone who participates will have NIRS and/or EEG exams during movement. People with cerebral palsy may also have biofeedback sessions to train coordination of movement and brain activity. - Participants will be screened with a physical exam and medical history. Urine samples may be collected. - All participants will have at least one session of NIRS and/or EEG imaging studies. Sessions may also include the following tests: - Magnetic resonance imaging to look at the brain - Electromyography to measure electrical activity of the muscles - Motion analysis of specific body parts - Ultrasound to measure activity of the muscles - Motorized, robotic, and electrical stimulation of the muscles - Other clinical tests of muscle movement as needed. - Participants with cerebral palsy will have biofeedback sessions. These sessions will help them learn to coordinate muscle movement and brain activity.

Background: - Researchers are interested in studying disorders that make individuals more susceptible to fungal infections, specifically infections with the Candida yeast. These disorders are often related to problems with the immune system and may have genetic factors, which suggests that researchers should study not only the individual with the disorder, but also his or her first- and second-degree relatives (such as parents, siblings, children, and first cousins). To provide material for future research, individuals with immune disorders and their first- and second-degree relatives will be asked to provide blood and other samples for testing and comparison with samples taken from healthy volunteers with no history of immune disorders. Objectives: - To collect blood and other biological samples to study immune disorders that make individuals more susceptible to fungal infections. Eligibility: - Individuals of any age who have abnormal immune function characterized by recurrent or unusual fungal infections, recurrent or chronic inflammation, or other types of immune dysfunction. - First- or second-degree genetically related family members (limited to mother, father, siblings, grandparents, children, aunts, uncles, and first cousins). - Healthy volunteers at least 18 years of age (for comparison purposes). Design: - Participants will provide blood samples and buccal (cells from the inside of the mouth near the cheek) samples. - Participants with immune disorders will also be asked to provide urine samples, saliva or mucosal samples, or skin tissue biopsies, and may also have imaging studies (such as x-rays) to collect information for research. - Samples may be collected at the National Institutes of Health or at other clinical locations for the samples to the sent to the National Institutes of Health. - No treatment will be provided as part of this protocol.

Background: Researchers have developed a new radioactive tracer (11C-ARMI). A tracer is a drug that attaches itself to other chemicals in the body and lights up so that the chemicals can be seen in imaging scans. The new tracer may be able to help them with many diseases, such as Alzheimer s disease and Parkinson s disease. Researchers want to test the new tracer in healthy people. Objective: To test a new tracer (11C-ARMI) during imaging scans of the brain and body in healthy people. Eligibility: Healthy people aged 18 years and older. They must have been screened under protocols 01-M-0254 or 17M0181. Design: All participants will have a positron emission tomography (PET)/computed tomography (CT) scan. Before the scan, they will have blood and urine tests and a test of their heart function. The tracer will be given through a tube attached to a needle inserted into a vein in the arm. They will lie on a padded bed that fits inside a doughnut-shaped machine; the machine uses x-rays to create images of the inside of the body. Some participants will have a PET/CT scan of their whole body. They will need only 1 visit. Some participants will have a PET/CT scan of only their brain. They will have up to 2 visits. On the second visit, they will have a magnetic resonance imaging (MRI) scan of the brain. For the MRI, they will lie on a table that slides into a cylinder. The MRI uses magnetic fields to create images of the inside of the body. Participants will receive a follow-up call to check on their well-being after their PET/CT scans.

Background: PDE4D is a protein in the body that plays a role in thinking and depression. This protein may play a major role in disorders such as Alzheimer disease or major depressive disorder. To learn more about these disorders, researchers want to be able to detect levels of PDE4D in the brain. 11C-JMJ-129 is a new radiotracer (a radioactive substance that highlights parts of the body during imaging scans) that was developed to attach only to PDE4D. However, early human studies showed that the tracer may break down in the body and create byproducts that interfere with the brain signal, making the results harder to interpret. This study will test whether a medication called disulfiram can improve PET imaging with 11C-JMJ-129. Disulfiram blocks an enzyme in the body that may be responsible for breaking down the tracer. By reducing this breakdown, the study aims to improve the quality and accuracy of brain images. The results may help researchers better measure PDE4D in the brain and support future studies of brain disorders. Objective: To test the new radiotracer 11C-JMJ-129, with and/or without disulfiram pretreatment during imaging scans in healthy volunteers. Eligibility: Healthy people aged 18 years and older who had a screening assessment under protocol 01-M-0254. Design: Participants will have 1 to 4 clinic visits. Participants will be screened. They will have a physical exam. They will have blood tests and a test of their heart function. Participants will undergo 1 or more of these scans: A positron emission tomography (PET) scan of the whole body. The radiotracer will be injected through a tube placed in a vein in the arm. Participants will lie on a table while a donut-shaped machine passes over them. Blood will be drawn from the arm during this scan. In Phase 5, disulfiram (500 mg orally) will be administered approximately 20 hours before the post-disulfiram PET scan A magnetic resonance imaging (MRI) scan of the brain. Participants will lie on a table that slides into a tube. A PET scan of the brain. These participants will be injected with the radiotracer. They will lie on a table with their head in the scanner. Participants will be called within 3 days after each PET scan for a check on their health.
