Study Summary
This study will examine the central regions and brain activation patterns associated with simple vocal behaviors under conditions of normal auditory feedback-when people hear themselves speak. Such feedback plays a major role in learning and maintaining human voice control. But voice control can be harmed by neurological injury or disease, reducing the ability of a person to orally communicate. Research has shown that auditory feedback is continuously monitored, brought about by both automatic and voluntary corrections in the amplitude (loudness) and frequency of (pitch) of the human voice. This study aims to determine which areas of the brain have activity dependent on the level of blood oxygen. It will provide new knowledge about basic vocal motor control and provide a basis for investigations into the integration of hearing and speaking in human vocal expression throughout life. Participants 18 to 45 years of age with normal hearing and voice function and with a steady heart rate may be eligible for this study. Participants will be evaluated by a speech-language specialist, regarding a history of voice health and measures of voice function. They will be tested on their ability to vary voice amplitude and frequency and tested on their hearing. Also, they will undergo an electrocardiogram to determine their heart rate. For the study, participants will undergo an MRI scan. During the MRI scan, patients will lie still on a table that can slide in and out of a metal cylinder surrounded by a strong magnetic field. Scanning time varies from 20 minutes to 3 hours, with most scans between 45 and 90 minutes. Patients may be asked to lie still for up to 90 minutes at a time. As the scanner takes pictures, there will be loud knocking noises, and patients will wear headphones to muffle the sound. The headphones will also enable patients to hear their voice. The patient's head will be positioned with a coil of 25 to 30 cm diameter and supported by a headrest. A microphone w
