Congenital prosopagnosia is a face recognition disorder that can not be associated with brain damage or birth complications. In such cases, based on parental reports, it can be stated that the disease is present from birth and the appearance of the problem can not be related to any obvious injury or changes of the central nervous system. It is known that infants are almost immediately interested in stimuli with facial configurations after birth, so it is suspected that the disturbance of this congenital facial preference is in the background of congenital prosopagnosia.

Since the disorder can be observed from birth, the role of hereditary factors cannot be excluded in these cases. Hereditary prosopagnosia is an appropriate term in cases (though often used incorrectly as a synonym for congenital) where at least one person with a facial recognition disorder is found among blood relatives. Results regarding the genetic background of the disorder is limited, but the succession pattern of prosopagnosia appearing in a single family can be deduced from the succession process.

Our research focuses on behavioral features and electrophysiological correlates of congenital prosopagnosia. We use behavioral tests and a 64-channel EEG system to measure and analyze electric signals of the brain while the subjects are taking tests.
