Adriana Galvan, PhD, studies the brain regions involved in movement planning and execution known as the basal ganglia. These structures are deeply affected in movement disorders, such as Parkinson’s disease. Dr. Galvan studies the basal ganglia functions and anatomy in rhesus macaques because the brain of these animals is closer to the human brain than other animal model and because macaques can provide a faithful model of the motor problems people who have Parkinson’s disease experience.
