Clinical trials: Vascular Function in Healthy Volunteers
Aphasia, Cerebrovascular Accident
Role of the Right Brain in Recovery of Language Function in Chronic Stroke
This study will examine in healthy individuals and in patients with aphasia (a language disturbance that is usually caused by stroke, brain disease, or injury) which parts of the brain are involved in naming everyday objects.
