Study Summary
This study will gain information on methods of control of a prosthetic arm in stroke patients or traumatic brain inury patients through a technique called "brain-computer interface" (BCI). BCI allows for direct communication between man and machine. Brain cells communicate by producing electrical impulses that help to create such things as thoughts, memory, consciousness and emotions. In BCI, brain waves are recorded by an electroencephalogram (EEG) through electrodes (small wires) attached to the scalp. The electrodes measure the electrical signals of the brain. These signals are sent to the computer, which translates them into device control commands as messages that reflect a person's intention. This type of brain activity comes from the sensorimotor areas of the brain and can be controlled through voluntarily training to control the hand prosthesis through the BCI. Healthy normal volunteers and people who have had a stroke or traumatic brain injury more than 12 months ago and have paralysis in the right or left arm, hand or leg and who are between 18 and 80 years of age may be eligible for this study. Candidates are screened with a clinical and neurological examination and magnetic resonance imaging (MRI) of the brain. MRI uses a magnetic field and radio waves to obtain images of the brain. The scanner is a metal cylinder surrounded by a strong magnetic field. During the procedure, the subject lies in the scanner for about 45 minutes, wearing ear plugs to muffle loud knocking sounds that occur with the scanning. Participants undergo the following procedures: * Sessions 1-2: Participants are connected to an EEG machine and familiarized with the hand orthosis (training device used in the study) and the tasks required for the study. * Sessions 3-4: Participants receive baseline transcranial magnetic stimulation (TMS) and fMRI. For TMS, a wire coil is held on the scalp. A brief electrical current is passed through the coil, creating a magnetic pulse that stimulat
