Dr. Perkel studies vocal learning in birds as a model for understanding speech learning in humans. Vocal learning involves learning new communication sounds, such as new words, by listening to others. Perkel and his team study neural circuits, including a major pathway involving the basal ganglia, which allow some songbirds to learn new songs. Since these circuits are similar to those in mammals, songbirds can serve as models of vocal learning in humans. A better understanding of vocal learning could contribute to therapies for persons with developmental disabilities that affect their ability to speak and learn language as well as to a broader understanding of developmental disorders that affect complex social behaviors.
Dr. Perkel also studies dopamine modulation of auditory responses in the inferior colliculus, a region of the auditory system that has specializations for processing complex sounds such as speech vocalizations.
